<h3>Description</h3>
|
||||
|
||||
<p>A Collection is a <i>concept</i> similar to the STL <a href=
|
||||
"http://www.sgi.com/tech/stl/Container.html">Container</a> concept. A
|
||||
Collection provides iterators for accessing a range of elements and
|
||||
provides information about the number of elements in the Collection.
|
||||
However, a Collection has fewer requirements than a Container. The
|
||||
motivation for the Collection concept is that there are many useful
|
||||
Container-like types that do not meet the full requirements of Container,
|
||||
and many algorithms that can be written with this reduced set of
|
||||
requirements. To summarize the reduction in requirements:</p>
|
||||
|
||||
<ul>
|
||||
<li>It is not required to "own" its elements: the lifetime of an element
|
||||
in a Collection does not have to match the lifetime of the Collection
|
||||
object, though the lifetime of the element should cover the lifetime of
|
||||
the Collection object.</li>
|
||||
|
||||
<li>The semantics of copying a Collection object is not defined (it could
|
||||
be a deep or shallow copy or not even support copying).</li>
|
||||
|
||||
<li>The associated reference type of a Collection does not have to be a
|
||||
real C++ reference.</li>
|
||||
</ul>Because of the reduced requirements, some care must be taken when
|
||||
writing code that is meant to be generic for all Collection types. In
|
||||
particular, a Collection object should be passed by-reference since
|
||||
assumptions can not be made about the behaviour of the copy constructor.

<h3>Collection Refinements</h3>
|
||||
|
||||
<p>There are quite a few concepts that refine the Collection concept,
|
||||
similar to the concepts that refine the Container concept. Here is a brief
|
||||
overview of the refining concepts.</p>
|
||||
|
||||
<h4>ForwardCollection</h4>
|
||||
|
||||
<p>The elements are arranged in some order that does not change
|
||||
spontaneously from one iteration to the next. As a result, a
|
||||
ForwardCollection is <a href=
|
||||
"http://www.sgi.com/tech/stl/EqualityComparable.html">EqualityComparable</a>
|
||||
and <a href=
|
||||
"http://www.sgi.com/tech/stl/LessThanComparable.html">LessThanComparable</a>.
|
||||
In addition, the iterator type of a ForwardCollection is a
|
||||
MultiPassInputIterator which is just an InputIterator with the added
|
||||
requirements that the iterator can be used to make multiple passes through
|
||||
a range, and that if <tt>it1 == it2</tt> and <tt>it1</tt> is
|
||||
dereferenceable then <tt>++it1 == ++it2</tt>. The ForwardCollection also
|
||||
has a <tt>front()</tt> method.</p>

</tr>
|

</table>
|
||||
|
||||
<h4>ReversibleCollection</h4>
|
||||
|
||||
<p>The container provides access to iterators that traverse in both
|
||||
directions (forward and reverse). The iterator type must meet all of the
|
||||
requirements of <a href=
|
||||
"http://www.sgi.com/tech/stl/BidirectionalIterator.html">BidirectionalIterator</a>
|
||||
except that the reference type does not have to be a real C++ reference.
|

The ReversibleCollection adds the following requirements to those of
|
||||
ForwardCollection.</p>

<h3>Notes</h3>
|
||||
|
||||
<p><a name="n1" id="n1">[1]</a> The reference type does not have to be a
|
||||
real C++ reference. The requirements of the reference type depend on the
|
||||
context within which the Collection is being used. Specifically it depends
|
||||
on the requirements the context places on the value type of the Collection.
|
||||
The reference type of the Collection must meet the same requirements as the
|
||||
value type. In addition, the reference objects must be equivalent to the
|
||||
value type objects in the collection (which is trivially true if they are
|
||||
the same object). Also, in a mutable Collection, an assignment to the

<p>A type is LessThanComparable if it is ordered: it must be possible to

<h3>Definitions</h3>
|

|

<p>Consider the relation <tt>!(x < y) && !(y < x)</tt>. If
|
||||
this relation is transitive (that is, if <tt>!(x < y) && !(y
|
||||
< x) && !(y < z) && !(z < y)</tt> implies <tt>!(x
|
||||
< z) && !(z < x)</tt>), then it satisfies the mathematical
|
||||
definition of an equivalence relation. In this case, <tt>operator<</tt>
|
||||
is a <i>strict weak ordering</i>.</p>
|
||||
|
||||
<p>If <tt>operator<</tt> is a strict weak ordering, and if each
|
||||
equivalence class has only a single element, then <tt>operator<</tt> is
|
||||
a <i>total ordering</i>.</p>

<p> I think that introducing MultiPassInputIterator isn't the right
|
||||
solution. Do you also want to define MultiPassBidirectionnalIterator
|
||||
and MultiPassRandomAccessIterator ? I don't, definitly. It only
|
||||
confuses the issue. The problem lies into the existing hierarchy of
|
||||
iterators, which mixes movabillity, modifiabillity and lvalue-ness,
|
||||
and these are clearly independant.

<p> The terms Forward, Bidirectionnal and RandomAccess are about

movabillity and shouldn't be used to mean anything else. In a

completly orthogonal way, iterators can be immutable, mutable, or
|
||||
neither. Lvalueness of iterators is also orthogonal with
|
||||
immutabillity. With these clean concepts, your MultiPassInputIterator
|
||||
is just called a ForwardIterator.

The above analysis by Valentin is right on. Of course, there is
|
||||
the problem with backward compatibility. The current STL implementations
|
||||
are based on the old definition of ForwardIterator. The right course
|
||||
of action is to get ForwardIterator, etc. changed in the C++ standard.
|
||||
Once that is done we can drop MultiPassInputIterator.

<h3>Description</h3>
|
||||
A type is a model of <i>OptionalPointee</i> if it points to (or refers to) a value
|
||||
that may not exist. That is, if it has a <b>pointee</b> which might be <b>valid</b>
|
||||
(existent) or <b>invalid</b> (inexistent); and it is possible to test whether the
|
||||
pointee is valid or not.
|
||||
This model does <u>not</u> imply pointer semantics: i.e., it does not imply shallow copy nor
|
||||
aliasing.

<h3>OptionalPointee and relational operations</h3>
|
||||
<p>This concept does not define any particular semantic for relational operations, therefore,
|
||||
a type which models this concept might have either shallow or deep relational semantics.<br>
|
||||
For instance, pointers, which are models of OptionalPointee, have shallow relational operators:
|
||||
comparisons of pointers do not involve comparisons of pointees.
|
||||
This makes sense for pointers because they have shallow copy semantics.<br>
|
||||
But boost::optional<T>, on the other hand, which is also a model of OptionalPointee, has
|
||||
deep-copy and deep-relational semantics.<br>
|
||||
If generic code is written for this concept, it is important not to use relational
|
||||
operators directly because the semantics might be different depending on the actual type.<br>
|
||||
Still, the concept itsef can be used to define <i>deep</i> relational tests that can
|
||||
be used in generic code with any type which models OptionalPointee:</p>
|
||||
<a name="equal"></a>
|
||||
<p><u>Equivalence relation:</u></p>
|
||||
<pre>template<class OptionalPointee>
|
||||
inline
|
||||
bool equal_pointees ( OptionalPointee const& x, OptionalPointee const& y )
|
||||
{
|
||||
return (!x) != (!y) ? false : ( !x ? true : (*x) == (*y) ) ;
|
||||
}
|
||||
template<class OptionalPointee>
|
||||
struct equal_pointees_t : std::binary_function<OptionalPointee,OptionalPointee,bool>
|
||||
{
|
||||
bool operator() ( OptionalPointee const& x, OptionalPointee const& y ) const
|
||||
{ return equal_pointees(x,y) ; }
|
||||
} ;
|
||||
</pre>
|
||||
<p>The preceding generic function and function object have the following semantics:<br>
|
||||
If both <b>x</b> and <b>y</b> have valid pointees, it compares values via <code>(*x == *y)</code>.<br>
|
||||
If only one has a valid pointee, returns <code>false</code>.<br>
|
||||
If both have invalid pointees, returns <code>true</code>.</p>
|
||||
<a name="less"></a>
|
||||
<p><u>Less-than relation:</u></p>
|
||||
<pre>template<class OptionalPointee>
|
||||
inline
|
||||
bool less_pointees ( OptionalPointee const& x, OptionalPointee const& y )
|
||||
{
|
||||
return !y ? false : ( !x ? true : (*x) < (*y) ) ;
|
||||
}
|
||||
template<class OptionalPointee>
|
||||
struct less_pointees_t : std::binary_function<OptionalPointee,OptionalPointee,bool>
|
||||
{
|
||||
bool operator() ( OptionalPointee const& x, OptionalPointee const& y ) const
|
||||
{ return less_pointees(x,y) ; }
|
||||
} ;
|
||||
</pre>
|
||||
<p>The preceding generic function and function object have the following semantics:<br>
|
||||
If <b>y</b> has an invalid pointee, returns <code>false</code>.<br>
|
||||
Else, if <b>x</b> has an invalid pointee, returns <code>true</code>.<br>
|
||||
Else, ( <b>x</b> and <b>y</b> have valid pointees), compares values via <code>(*x <
|
||||
*y).</code></p>
|
||||
<p><br>
|
||||
All these functions and function
|
||||
objects are is implemented in <a href="../../boost/utility/compare_pointees.hpp">compare_pointees.hpp</a></p>
|
||||
<p>Notice that OptionalPointee does not imply aliasing (and optional<> for instance does not alias);
|
||||
so direct usage of relational operators with the implied aliasing of shallow semantics
|
||||
-as with pointers- should not be used with generic code written for this concept.</p>

Boost.Utility, part of collection of the [Boost C++ Libraries](https://github.com/boostorg), provides a number of smaller components, too small to be called libraries in their own right. See the documentation for the list of components.
|
||||
|
||||
### Directories
|
||||
|
||||
* **doc** - Documentation sources
|
||||
* **include** - Interface headers of Boost.Utility
|
||||
* **test** - Boost.Utility unit tests
|
||||
|
||||
### More information
|
||||
|
||||
* [Documentation](https://boost.org/libs/utility)
|
||||
* [Report bugs](https://github.com/boostorg/utility/issues/new). Be sure to mention Boost version, Boost.Utility component, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
|
||||
* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](https://www.boost.org/LICENSE_1_0.txt).

* opt::fill - optimised for trivial copy/small types (cf std::fill)
|

* opt::destroy_array - an example of optimisation based upon omitted destructor calls
|

* opt::iter_swap - uses type_traits to determine whether the iterator is a proxy
|

* in which case it uses a "safe" approach, otherwise calls swap
|

/* Release notes:
|
||||
23rd July 2000:
|
||||
Added explicit failure for broken compilers that don't support these examples.
|
||||
Fixed broken gcc support (broken using directive).
|
||||
Reordered tests slightly.

<p align="center"><em>by John Maddock and Steve Cleary</em></p>
|

<p align="center"><em>This is a draft of an article that will appear in a future
|
||||
issue of </em><a href="http://www.ddj.com"><em>Dr Dobb's Journal</em></a></p>
|
||||
<p>Generic programming (writing code which works with any data type meeting a
|
||||
set of requirements) has become the method of choice for providing reusable
|
||||
code. However, there are times in generic programming when "generic"
|
||||
just isn't good enough - sometimes the differences between types are too large
|
||||
for an efficient generic implementation. This is when the traits technique
|
||||
becomes important - by encapsulating those properties that need to be considered
|
||||
on a type by type basis inside a traits class, we can minimise the amount of
|
||||
code that has to differ from one type to another, and maximise the amount of
|
||||
generic code.</p>
|
||||
<p>Consider an example: when working with character strings, one common
|
||||
operation is to determine the length of a null terminated string. Clearly it's
|
||||
possible to write generic code that can do this, but it turns out that there are
|
||||
much more efficient methods available: for example, the C library functions <font size="2" face="Courier New">strlen</font>
|
||||
and <font size="2" face="Courier New">wcslen</font> are usually written in
|
||||
assembler, and with suitable hardware support can be considerably faster than a
|
||||
generic version written in C++. The authors of the C++ standard library realised
|
||||
this, and abstracted the properties of <font size="2" face="Courier New">char</font>
|
||||
and <font size="2" face="Courier New">wchar_t</font> into the class <font size="2" face="Courier New">char_traits</font>.
|
||||
Generic code that works with character strings can simply use <font size="2" face="Courier New">char_traits<>::length</font>
|
||||
to determine the length of a null terminated string, safe in the knowledge that
|
||||
specialisations of <font size="2" face="Courier New">char_traits</font> will use
|
||||
the most appropriate method available to them.</p>
|
||||
<h4>Type traits</h4>
|
||||
<p>Class <font size="2" face="Courier New">char_traits</font> is a classic
|
||||
example of a collection of type specific properties wrapped up in a single class
|
||||
- what Nathan Myers termed a <i>baggage class</i>[1]. In the Boost type-traits
|
||||
library, we[2] have written a set of very specific traits classes, each of which
|
||||
encapsulate a single trait from the C++ type system; for example, is a type a
|
||||
pointer or a reference type? Or does a type have a trivial constructor, or a
|
||||
const-qualifier? The type-traits classes share a unified design: each class has
|
||||
a single member <i>value</i>, a compile-time constant that is true if the type
|
||||
has the specified property, and false otherwise. As we will show, these classes
|
||||
can be used in generic programming to determine the properties of a given type
|
||||
and introduce optimisations that are appropriate for that case.</p>
|
||||
<p>The type-traits library also contains a set of classes that perform a
|
||||
specific transformation on a type; for example, they can remove a top-level
|
||||
const or volatile qualifier from a type. Each class that performs a
|
||||
transformation defines a single typedef-member <i>type</i> that is the result of
|
||||
the transformation. All of the type-traits classes are defined inside namespace <font size="2" face="Courier New">boost</font>;
|
||||
for brevity, namespace-qualification is omitted in most of the code samples
|
||||
given.</p>
|
||||
<h4>Implementation</h4>
|
||||
<p>There are far too many separate classes contained in the type-traits library
|
||||
to give a full implementation here - see the source code in the Boost library
|
||||
for the full details - however, most of the implementation is fairly repetitive
|
||||
anyway, so here we will just give you a flavour for how some of the classes are
|
||||
implemented. Beginning with possibly the simplest class in the library, is_void<T>
|
||||
has a member <i>value</i> that is true only if T is void.</p>
|
||||
<pre>template <typename T>
|
||||
struct is_void
|
||||
{ static const bool value = false; };
|
||||
|
||||
template <>
|
||||
struct is_void<void>
|
||||
{ static const bool value = true; };</pre>
|
||||
<p>Here we define a primary version of the template class <font size="2" face="Courier New">is_void</font>,
|
||||
and provide a full-specialisation when T is void. While full specialisation of a
|
||||
template class is an important technique, sometimes we need a solution that is
|
||||
halfway between a fully generic solution, and a full specialisation. This is
|
||||
exactly the situation for which the standards committee defined partial
|
||||
template-class specialisation. As an example, consider the class
|
||||
boost::is_pointer<T>: here we needed a primary version that handles all
|
||||
the cases where T is not a pointer, and a partial specialisation to handle all
|
||||
the cases where T is a pointer:</p>
|
||||
<pre>template <typename T>
|
||||
struct is_pointer
|
||||
{ static const bool value = false; };
|
||||
|
||||
template <typename T>
|
||||
struct is_pointer<T*>
|
||||
{ static const bool value = true; };</pre>
|
||||
<p>The syntax for partial specialisation is somewhat arcane and could easily
|
||||
occupy an article in its own right; like full specialisation, in order to write
|
||||
a partial specialisation for a class, you must first declare the primary
|
||||
template. The partial specialisation contains an extra <<EFBFBD>> after the
|
||||
class name that contains the partial specialisation parameters; these define the
|
||||
types that will bind to that partial specialisation rather than the default
|
||||
template. The rules for what can appear in a partial specialisation are somewhat
|
||||
convoluted, but as a rule of thumb if you can legally write two function
|
||||
overloads of the form:</p>
|
||||
<pre>void foo(T);
|
||||
void foo(U);</pre>
|
||||
<p>Then you can also write a partial specialisation of the form:</p>
|
||||
<pre>template <typename T>
|
||||
class c{ /*details*/ };
|
||||
|
||||
template <typename T>
|
||||
|
||||
class c<U>{ /*details*/ };</pre>
|
||||
<p>This rule is by no means foolproof, but it is reasonably simple to remember
|
||||
and close enough to the actual rule to be useful for everyday use.</p>
|
||||
<p>As a more complex example of partial specialisation consider the class
|
||||
remove_bounds<T>. This class defines a single typedef-member <i>type</i>
|
||||
that is the same type as T but with any top-level array bounds removed; this is
|
||||
an example of a traits class that performs a transformation on a type:</p>
|
||||
<pre>template <typename T>
|
||||
struct remove_bounds
|
||||
{ typedef T type; };
|
||||
|
||||
template <typename T, std::size_t N>
|
||||
struct remove_bounds<T[N]>
|
||||
{ typedef T type; };</pre>
|
||||
<p>The aim of remove_bounds is this: imagine a generic algorithm that is passed
|
||||
an array type as a template parameter, <font size="2" face="Courier New">remove_bounds</font>
|
||||
provides a means of determining the underlying type of the array. For example <code>remove_bounds<int[4][5]>::type</code>
|
||||
would evaluate to the type <code>int[5]</code>. This example also shows that the
|
||||
number of template parameters in a partial specialisation does not have to match
|
||||
the number in the default template. However, the number of parameters that
|
||||
appear after the class name do have to match the number and type of the
|
||||
parameters in the default template.</p>
|
||||
<h4>Optimised copy</h4>
|
||||
<p>As an example of how the type traits classes can be used, consider the
|
||||
standard library algorithm copy:</p>
|
||||
<pre>template<typename Iter1, typename Iter2>
|
||||
Iter2 copy(Iter1 first, Iter1 last, Iter2 out);</pre>
|
||||
<p>Obviously, there's no problem writing a generic version of copy that works
|
||||
for all iterator types Iter1 and Iter2; however, there are some circumstances
|
||||
when the copy operation can best be performed by a call to <font size="2" face="Courier New">memcpy</font>.
|
||||
In order to implement copy in terms of <font size="2" face="Courier New">memcpy</font>
|
||||
all of the following conditions need to be met:</p>
|
||||
<ul>
|
||||
<li>Both of the iterator types Iter1 and Iter2 must be pointers.</li>
|
||||
<li>Both Iter1 and Iter2 must point to the same type - excluding <font size="2" face="Courier New">const</font>
|
||||
and <font size="2" face="Courier New">volatile</font>-qualifiers.</li>
|
||||
<li>The type pointed to by Iter1 must have a trivial assignment operator.</li>
|
||||
</ul>
|
||||
<p>By trivial assignment operator we mean that the type is either a scalar
|
||||
type[3] or:</p>
|
||||
<ul>
|
||||
<li>The type has no user defined assignment operator.</li>
|
||||
<li>The type does not have any data members that are references.</li>
|
||||
<li>All base classes, and all data member objects must have trivial assignment
|
||||
operators.</li>
|
||||
</ul>
|
||||
<p>If all these conditions are met then a type can be copied using <font size="2" face="Courier New">memcpy</font>
|
||||
rather than using a compiler generated assignment operator. The type-traits
|
||||
library provides a class <i>has_trivial_assign</i>, such that <code>has_trivial_assign<T>::value</code>
|
||||
is true only if T has a trivial assignment operator. This class "just
|
||||
works" for scalar types, but has to be explicitly specialised for
|
||||
class/struct types that also happen to have a trivial assignment operator. In
|
||||
other words if <i>has_trivial_assign</i> gives the wrong answer, it will give
|
||||
the "safe" wrong answer - that trivial assignment is not allowable.</p>
|
||||
<p>The code for an optimised version of copy that uses <font size="2" face="Courier New">memcpy</font>
|
||||
where appropriate is given in listing 1. The code begins by defining a template
|
||||
class <i>copier</i>, that takes a single Boolean template parameter, and has a
|
||||
static template member function <font size="2" face="Courier New">do_copy</font>
|
||||
which performs the generic version of <font size="2">copy</font> (in other words
|
||||
the "slow but safe version"). Following that there is a specialisation
|
||||
for <i>copier<true></i>: again this defines a static template member
|
||||
function <font size="2" face="Courier New">do_copy</font>, but this version uses
|
||||
memcpy to perform an "optimised" copy.</p>
|
||||
<p>In order to complete the implementation, what we need now is a version of
|
||||
copy, that calls <code>copier<true>::do_copy</code> if it is safe to use <font size="2" face="Courier New">memcpy</font>,
|
||||
and otherwise calls <code>copier<false>::do_copy</code> to do a
|
||||
"generic" copy. This is what the version in listing 1 does. To
|
||||
understand how the code works look at the code for <font size="2" face="Courier New">copy</font>
|
||||
and consider first the two typedefs <i>v1_t</i> and <i>v2_t</i>. These use <code>std::iterator_traits<Iter1>::value_type</code>
|
||||
to determine what type the two iterators point to, and then feed the result into
|
||||
another type-traits class <i>remove_cv</i> that removes the top-level
|
||||
const-volatile-qualifiers: this will allow copy to compare the two types without
|
||||
regard to const- or volatile-qualifiers. Next, <font size="2" face="Courier New">copy</font>
|
||||
declares an enumerated value <i>can_opt</i> that will become the template
|
||||
parameter to copier - declaring this here as a constant is really just a
|
||||
convenience - the value could be passed directly to class <font size="2" face="Courier New">copier</font>.
|
||||
The value of <i>can_opt</i> is computed by verifying that all of the following
|
||||
are true:</p>
|
||||
<ul>
|
||||
<li>first that the two iterators point to the same type by using a type-traits
|
||||
class <i>is_same</i>.</li>
|
||||
<li>Then that both iterators are real pointers - using the class <i>is_pointer</i>
|
||||
described above.</li>
|
||||
<li>Finally that the pointed-to types have a trivial assignment operator using
|
||||
<i>has_trivial_assign</i>.</li>
|
||||
</ul>
|
||||
<p>Finally we can use the value of <i>can_opt</i> as the template argument to
|
||||
copier - this version of copy will now adapt to whatever parameters are passed
|
||||
to it, if its possible to use <font size="2" face="Courier New">memcpy</font>,
|
||||
then it will do so, otherwise it will use a generic copy.</p>
|
||||
<h4>Was it worth it?</h4>
|
||||
<p>It has often been repeated in these columns that "premature optimisation
|
||||
is the root of all evil" [4]. So the question must be asked: was our
|
||||
optimisation premature? To put this in perspective the timings for our version
|
||||
of copy compared a conventional generic copy[5] are shown in table 1.</p>
|
||||
<p>Clearly the optimisation makes a difference in this case; but, to be fair,
|
||||
the timings are loaded to exclude cache miss effects - without this accurate
|
||||
comparison between algorithms becomes difficult. However, perhaps we can add a
|
||||
couple of caveats to the premature optimisation rule:</p>
|
||||
<ul>
|
||||
<li>If you use the right algorithm for the job in the first place then
|
||||
optimisation will not be required; in some cases, <font size="2" face="Courier New">memcpy</font>
|
||||
is the right algorithm.</li>
|
||||
<li>If a component is going to be reused in many places by many people then
|
||||
optimisations may well be worthwhile where they would not be so for a single
|
||||
case - in other words, the likelihood that the optimisation will be
|
||||
absolutely necessary somewhere, sometime is that much higher. Just as
|
||||
importantly the perceived value of the stock implementation will be higher:
|
||||
there is no point standardising an algorithm if users reject it on the
|
||||
grounds that there are better, more heavily optimised versions available.</li>
|
||||
</ul>

<h4>Pair of References</h4>
|
||||
<p>The optimised copy example shows how type traits may be used to perform
|
||||
optimisation decisions at compile-time. Another important usage of type traits
|
||||
is to allow code to compile that otherwise would not do so unless excessive
|
||||
partial specialization is used. This is possible by delegating partial
|
||||
specialization to the type traits classes. Our example for this form of usage is
|
||||
a pair that can hold references [6].</p>
|
||||
<p>First, let us examine the definition of "std::pair", omitting the
|
||||
comparision operators, default constructor, and template copy constructor for
|
||||
simplicity:</p>
|
||||
<pre>template <typename T1, typename T2>
|
||||
struct pair
|
||||
{
|
||||
typedef T1 first_type;
|
||||
typedef T2 second_type;
|
||||
|
||||
T1 first;
|
||||
T2 second;
|
||||
|
||||
pair(const T1 & nfirst, const T2 & nsecond)
|
||||
:first(nfirst), second(nsecond) { }
|
||||
};</pre>
|
||||
<p>Now, this "pair" cannot hold references as it currently stands,
|
||||
because the constructor would require taking a reference to a reference, which
|
||||
is currently illegal [7]. Let us consider what the constructor's parameters
|
||||
would have to be in order to allow "pair" to hold non-reference types,
|
||||
references, and constant references:</p>
|
||||
<table border="1" cellpadding="7" cellspacing="1" width="638">
|
||||
<tr>
|
||||
<td valign="top" width="50%">Type of "T1"</td>
|
||||

</td>
|
||||
</tr>
|
||||
</table>
|
||||
<p>A little familiarity with the type traits classes allows us to construct a
|
||||
single mapping that allows us to determine the type of parameter from the type
|
||||
of the contained class. The type traits classes provide a transformation "add_reference",
|
||||
which adds a reference to its type, unless it is already a reference.</p>

<p>This allows us to build a primary template definition for "pair"
|
||||
that can contain non-reference types, reference types, and constant reference
|
||||
types:</p>
|
||||
<pre>template <typename T1, typename T2>
|
||||
struct pair
|
||||
{
|
||||
typedef T1 first_type;
|
||||
typedef T2 second_type;
|
||||
|
||||
T1 first;
|
||||
T2 second;
|
||||
|
||||
pair(boost::add_reference<const T1>::type nfirst,
|
||||
boost::add_reference<const T2>::type nsecond)
|
||||
:first(nfirst), second(nsecond) { }
|
||||
};</pre>
|
||||
<p>Add back in the standard comparision operators, default constructor, and
|
||||
template copy constructor (which are all the same), and you have a std::pair
|
||||
that can hold reference types!</p>
|
||||
<p>This same extension <i>could</i> have been done using partial template
|
||||
specialization of "pair", but to specialize "pair" in this
|
||||
way would require three partial specializations, plus the primary template. Type
|
||||
traits allows us to define a single primary template that adjusts itself
|
||||
auto-magically to any of these partial specializations, instead of a brute-force
|
||||
partial specialization approach. Using type traits in this fashion allows
|
||||
programmers to delegate partial specialization to the type traits classes,
|
||||
resulting in code that is easier to maintain and easier to understand.</p>
|
||||
<h4>Conclusion</h4>
|
||||
<p>We hope that in this article we have been able to give you some idea of what
|
||||
type-traits are all about. A more complete listing of the available classes are
|
||||
in the boost documentation, along with further examples using type traits.
|
||||
Templates have enabled C++ uses to take the advantage of the code reuse that
|
||||
generic programming brings; hopefully this article has shown that generic
|
||||
programming does not have to sink to the lowest common denominator, and that
|
||||
templates can be optimal as well as generic.</p>

a "reference to a reference to T" to mean the same thing as a

"reference to T", but only in template instantiation, in a method

remember that references are always implicitly constant (for example, you

can't re-assign a reference). Remember also that "const T &"
|

is something completely different. For this reason, cv-qualifiers on
|

template type arguments that are references are ignored.</li>

<h3>Namespace synopsis</h3>
|
||||
<blockquote>
|
||||
<pre>namespace boost {
|
||||
namespace cast {
|
||||
// all synopsis below included here
|
||||
}
|
||||
using ::boost::cast::polymorphic_cast;
|
||||
using ::boost::cast::polymorphic_downcast;
|
||||
using ::boost::cast::bad_numeric_cast;
|
||||
using ::boost::cast::numeric_cast;

</blockquote>
|
||||
<h3><a name="Polymorphic_cast">Polymorphic casts</a></h3>
|
||||
<p>Pointers to polymorphic objects (objects of classes which define at least one
|
||||
virtual function) are sometimes downcast or crosscast. Downcasting means
|
||||
casting from a base class to a derived class. Crosscasting means casting
|
||||
across an inheritance hierarchy diagram, such as from one base to the other in a
|
||||
<b>Y</b> diagram hierarchy.</p>
|
||||
<p>Such casts can be done with old-style casts, but this approach is never to be
|
||||
recommended. Old-style casts are sorely lacking in type safety, suffer
|
||||
poor readability, and are difficult to locate with search tools.</p>
|
||||
<p>The C++ built-in <b>static_cast</b> can be used for efficiently downcasting
|
||||
pointers to polymorphic objects, but provides no error detection for the case
|
||||
where the pointer being cast actually points to the wrong derived class. The <b>polymorphic_downcast</b>
|
||||
template retains the efficiency of <b>static_cast</b> for non-debug
|
||||
compilations, but for debug compilations adds safety via an assert() that a <b>dynamic_cast</b>
|
||||
succeeds. <b> </b></p>
|
||||
<p>The C++ built-in <b>dynamic_cast</b> can be used for downcasts and crosscasts
|
||||
of pointers to polymorphic objects, but error notification in the form of a
|
||||
returned value of 0 is inconvenient to test, or worse yet, easy to forget to
|
||||
test. The <b>polymorphic_cast</b> template performs a <b>dynamic_cast</b>,
|
||||
and throws an exception if the <b>dynamic_cast</b> returns 0.</p>
|
||||
<p>A <b>polymorphic_downcast</b> is preferred when debug-mode tests will cover
|
||||
100% of the object types possibly cast and when non-debug-mode efficiency is an
|
||||
issue. If these two conditions are not present, <b>polymorphic_cast</b> is
|
||||
preferred. It must also be used for crosscasts. It does an assert(
|
||||
dynamic_cast<Derived>(x) == x ) where x is the base pointer, ensuring that
|
||||
not only is a non-zero pointer returned, but also that it correct in the
|
||||
presence of multiple inheritance. .<b> Warning:</b>: Because <b>polymorphic_downcast</b>
|
||||
uses assert(), it violates the One Definition Rule if NDEBUG is inconsistently
|
||||
defined across translation units.</p>
|
||||
<p>The C++ built-in <b>dynamic_cast</b> must be used to cast references rather
|
||||
than pointers. It is also the only cast that can be used to check whether
|
||||
a given interface is supported; in that case a return of 0 isn't an error
|
||||
condition.</p>

||||
<h3>polymorphic_cast and polymorphic_downcast synopsis</h3>
|
||||
<blockquote>
|
||||
<pre>template <class Derived, class Base>
|
||||
inline Derived polymorphic_cast(Base* x);
|
||||
// Throws: std::bad_cast if ( dynamic_cast<Derived>(x) == 0 )
|
||||
// Returns: dynamic_cast<Derived>(x)
|
||||
|
||||
template <class Derived, class Base>
|
||||
inline Derived polymorphic_downcast(Base* x);
|
||||
// Effects: assert( dynamic_cast<Derived>(x) == x );
|
||||
// Returns: static_cast<Derived>(x)</pre>
|
||||
</blockquote>
|
||||
<h3>polymorphic_downcast example</h3>
|
||||
<blockquote>
|
||||
<pre>#include <boost/cast.hpp>
|
||||
...
|
||||
class Fruit { public: virtual ~Fruit(){}; ... };
|
||||
class Banana : public Fruit { ... };
|
||||
...
|
||||
void f( Fruit * fruit ) {
|
||||
// ... logic which leads us to believe it is a Banana
|
||||
Banana * banana = boost::polymorphic_downcast<Banana*>(fruit);
|
||||
...</pre>
|
||||
</blockquote>
|
||||
<h3><a name="numeric_cast">numeric_cast</a></h3>
|
||||
<p>A <b>static_cast</b>, <b>implicit_cast</b> or implicit conversion will not
|
||||
detect failure to preserve range for numeric casts. The <b>numeric_cast</b>
|
||||
template function are similar to <b>static_cast</b> and certain (dubious)
|
||||
implicit conversions in this respect, except that they detect loss of numeric
|
||||
range. An exception is thrown when a runtime value preservation check fails.</p>
|
||||
<p>The requirements on the argument and result types are:</p>
|
||||
<blockquote>
|
||||
<ul>
|
||||
<li>Both argument and result types are CopyConstructible [20.1.3].</li>
|
||||
<li>Both argument and result types are Numeric, defined by <code>std::numeric_limits<>::is_specialized</code>
|
||||
being true.</li>
|
||||
<li>The argument can be converted to the result type using <b>static_cast</b>.</li>
|
||||
</ul>
|
||||
</blockquote>
|
||||
<h3>numeric_cast synopsis</h3>
|
||||
<blockquote>
|
||||
<pre>class bad_numeric_cast : public std::bad_cast {...};
|
||||
|
||||
template<typename Target, typename Source>
|
||||
inline Target numeric_cast(Source arg);
|
||||
// Throws: bad_numeric_cast unless, in converting arg from Source to Target,
|
||||
// there is no loss of negative range, and no underflow, and no
|
||||
// overflow, as determined by std::numeric_limits
|
||||
// Returns: static_cast<Target>(arg)</pre>
|
||||
</blockquote>
|
||||
<h3>numeric_cast example</h3>
|
||||
<blockquote>
|
||||
<pre>#include <boost/cast.hpp>
|
||||
using namespace boost::cast;
|
||||
|
||||
void ariane(double vx)
|
||||
{
|
||||
...
|
||||
unsigned short dx = numeric_cast<unsigned short>(vx);
|
||||
...
|
||||
}</pre>
|
||||
</blockquote>
|
||||
<h3>numeric_cast rationale</h3>
|
||||
<p>The form of the throws condition is specified so that != is not a required
|
||||
operation.</p>

<p>The class compressed pair is very similar to std::pair, but if

typedef typename call_traits<first_type>::const_reference first_const_reference;
|

typedef typename call_traits<second_type>::const_reference second_const_reference;
|

compressed_pair() : base() {}
|

compressed_pair(first_param_type x, second_param_type y);

explicit compressed_pair(first_param_type x);

explicit compressed_pair(second_param_type y);

|
||||
|

void swap(compressed_pair& y);
|
||||
};</pre>
|
||||
|
||||
<p>The two members of the pair can be accessed using the member
|
||||
functions first() and second(). Note that not all member
|
||||
functions can be instantiated for all template parameter types.
|
||||
In particular compressed_pair can be instantiated for reference
|
||||
and array types, however in these cases the range of constructors
|
||||
that can be used are limited. If types T1 and T2 are the same
|
||||
type, then there is only one version of the single-argument
|
||||
constructor, and this constructor initialises both values in the
|
||||
pair to the passed value.</p>
|
||||
|
||||
<p>Note that compressed_pair can not be instantiated if either of
|
||||
the template arguments is an enumerator type, unless there is
|
||||
compiler support for boost::is_enum, or if boost::is_enum is
|
||||
specialised for the enumerator type.</p>
|
||||
|
||||
<p>Finally, compressed_pair requires compiler support for partial
|
||||
specialisation of class templates - without that support
|
||||
compressed_pair behaves just like std::pair.</p>

[section Rationale]
|
||||
|
||||
When developing a class, sometimes a base class needs to be initialized
|
||||
with a member of the current class. As a na\u00EFve example:
|
||||
|
||||
#include <streambuf> /* for std::streambuf */
|
||||
#include <ostream> /* for std::ostream */
|
||||
|
||||
class fdoutbuf
|
||||
: public std::streambuf
|
||||
{
|
||||
public:
|
||||
explicit fdoutbuf( int fd );
|
||||
//...
|
||||
};
|
||||
|
||||
class fdostream
|
||||
: public std::ostream
|
||||
{
|
||||
protected:
|
||||
fdoutbuf buf;
|
||||
public:
|
||||
explicit fdostream( int fd )
|
||||
: buf( fd ), std::ostream( &buf ) {}
|
||||
//...
|
||||
};
|
||||
|
||||
This is undefined because C++'s initialization order mandates that the base
|
||||
class is initialized before the member it uses. [@http://www.moocat.org R.
|
||||
Samuel Klatchko] developed a way around this by using the initialization
|
||||
order in his favor. Base classes are intialized in order of declaration, so
|
||||
moving the desired member to another base class, that is initialized before
|
||||
the desired base class, can ensure proper initialization.
|
||||
|
||||
A custom base class can be made for this idiom:
|
||||
|
||||
#include <streambuf> /* for std::streambuf */
|
||||
#include <ostream> /* for std::ostream */
|
||||
|
||||
class fdoutbuf
|
||||
: public std::streambuf
|
||||
{
|
||||
public:
|
||||
explicit fdoutbuf( int fd );
|
||||
//...
|
||||
};
|
||||
|
||||
struct fdostream_pbase
|
||||
{
|
||||
fdoutbuf sbuffer;
|
||||
|
||||
explicit fdostream_pbase( int fd )
|
||||
: sbuffer( fd ) {}
|
||||
};
|
||||
|
||||
class fdostream
|
||||
: private fdostream_pbase
|
||||
, public std::ostream
|
||||
{
|
||||
typedef fdostream_pbase pbase_type;
|
||||
typedef std::ostream base_type;
|
||||
|
||||
public:
|
||||
explicit fdostream( int fd )
|
||||
: pbase_type( fd ), base_type( &sbuffer ) {}
|
||||
//...
|
||||
};
|
||||
|
||||
Other projects can use similar custom base classes. The technique is basic
|
||||
enough to make a template, with a sample template class in this library.
|
||||
The main template parameter is the type of the enclosed member. The
|
||||
template class has several (explicit) constructor member templates, which
|
||||
implicitly type the constructor arguments and pass them to the member. The
|
||||
template class uses implicit copy construction and assignment, cancelling
|
||||
them if the enclosed member is non-copyable.
|
||||
|
||||
Manually coding a base class may be better if the construction and/or
|
||||
copying needs are too complex for the supplied template class, or if the
|
||||
compiler is not advanced enough to use it.
|
||||
|
||||
Since base classes are unnamed, a class cannot have multiple (direct) base
|
||||
classes of the same type. The supplied template class has an extra template
|
||||
parameter, an integer, that exists solely to provide type differentiation.
|
||||
This parameter has a default value so a single use of a particular member
|
||||
type does not need to concern itself with the integer.

protected:
|
||||
MemberType& member;
|
||||
|
||||
explicit constexpr base_from_member( MemberType& x )
|
||||
noexcept;
|
||||
};
|
||||
|
||||
The class template has a first template parameter `MemberType` representing
|
||||
the type of the based-member. It has a last template parameter `UniqueID`,
|
||||
that is an `int`, to differentiate between multiple base classes that use
|
||||
the same based-member type. The last template parameter has a default value
|
||||
of zero if it is omitted. The class template has a protected data member
|
||||
called `member` that the derived class can use for later base classes (or
|
||||
itself).
|
||||
|
||||
If the appropriate features of C++11 are present, there will be a single
|
||||
constructor template. It implements ['perfect forwarding] to the best
|
||||
constructor call of `member` (if any). The constructor template is marked
|
||||
both `constexpr` and `explicit`. The former will be ignored if the
|
||||
corresponding inner constructor call (of `member`) does not have the marker.
|
||||
The latter binds the other way; always taking effect, even when the inner
|
||||
constructor call does not have the marker. The constructor template
|
||||
propagates the `noexcept` status of the inner constructor call. (The
|
||||
constructor template has a trailing parameter with a default value that
|
||||
disables the template when its signature is too close to the signatures of
|
||||
the automatically-defined non-template copy- and/or move-constructors of
|
||||
`base_from_member`.)
|
||||
|
||||
On earlier-standard compilers, there is a default constructor and several
|
||||
constructor member templates. These constructor templates can take as many
|
||||
arguments (currently up to ten) as possible and pass them to a constructor
|
||||
of the data member.
|
||||
|
||||
A specialization for member references offers a single constructor taking
|
||||
a `MemberType&`, which is the only way to initialize a reference.
|
||||
|
||||
Since C++ does not allow any way to explicitly state the template parameters
|
||||
of a templated constructor, make sure that the arguments are already close
|
||||
as possible to the actual type used in the data member's desired constructor.
|
||||
Explicit conversions may be necessary.
|
||||
|
||||
The `BOOST_BASE_FROM_MEMBER_MAX_ARITY` macro constant specifies the maximum
|
||||
argument length for the constructor templates. The constant may be overridden
|
||||
if more (or less) argument configurations are needed. The constant may be
|
||||
read for code that is expandable like the class template and needs to
|
||||
maintain the same maximum size. (Example code would be a class that uses
|
||||
this class template as a base class for a member with a flexible set of
|
||||
constructors.) This constant is ignored when C++11 features are present.

[section Usage]
|
||||
|
||||
With the starting example, the `fdoutbuf` sub-object needs to be
|
||||
encapsulated in a base class that is inheirited before `std::ostream`.
|
||||
|
||||
#include <boost/utility/base_from_member.hpp>
|
||||
|
||||
#include <streambuf> // for std::streambuf
|
||||
#include <ostream> // for std::ostream
|
||||
|
||||
class fdoutbuf
|
||||
: public std::streambuf
|
||||
{
|
||||
public:
|
||||
explicit fdoutbuf( int fd );
|
||||
//...
|
||||
};
|
||||
|
||||
class fdostream
|
||||
: private boost::base_from_member<fdoutbuf>
|
||||
, public std::ostream
|
||||
{
|
||||
// Helper typedef's
|
||||
typedef boost::base_from_member<fdoutbuf> pbase_type;
|
||||
typedef std::ostream base_type;
|
||||
|
||||
public:
|
||||
explicit fdostream( int fd )
|
||||
: pbase_type( fd ), base_type( &member ){}
|
||||
//...
|
||||
};
|
||||
|
||||
The base-from-member idiom is an implementation detail, so it should not
|
||||
be visible to the clients (or any derived classes) of `fdostream`. Due to
|
||||
the initialization order, the `fdoutbuf` sub-object will get initialized
|
||||
before the `std::ostream` sub-object does, making the former sub-object
|
||||
safe to use in the latter sub-object's construction. Since the `fdoutbuf`
|
||||
sub-object of the final type is the only sub-object with the name `member`
|
||||
that name can be used unqualified within the final class.
|
||||
|
||||
[endsect]
|
||||
|
||||
[section Example]
|
||||
|
||||
The base-from-member class templates should commonly involve only one
|
||||
base-from-member sub-object, usually for attaching a stream-buffer to an
|
||||
I/O stream. The next example demonstrates how to use multiple
|
||||
base-from-member sub-objects and the resulting qualification issues.
|
||||
|
||||
#include <boost/utility/base_from_member.hpp>
|
||||
|
||||
#include <cstddef> /* for NULL */
|
||||
|
||||
struct an_int
|
||||
{
|
||||
int y;
|
||||
|
||||
an_int( float yf );
|
||||
};
|
||||
|
||||
class switcher
|
||||
{
|
||||
public:
|
||||
switcher();
|
||||
switcher( double, int * );
|
||||
//...
|
||||
};
|
||||
|
||||
class flow_regulator
|
||||
{
|
||||
public:
|
||||
flow_regulator( switcher &, switcher & );
|
||||
//...
|
||||
};
|
||||
|
||||
template < unsigned Size >
|
||||
class fan
|
||||
{
|
||||
public:
|
||||
explicit fan( switcher );
|
||||
//...
|
||||
};
|
||||
|
||||
class system
|
||||
: private boost::base_from_member<an_int>
|
||||
, private boost::base_from_member<switcher>
|
||||
, private boost::base_from_member<switcher, 1>
|
||||
, private boost::base_from_member<switcher, 2>
|
||||
, protected flow_regulator
|
||||
, public fan<6>
|
||||
{
|
||||
// Helper typedef's
|
||||
typedef boost::base_from_member<an_int> pbase0_type;
|
||||
typedef boost::base_from_member<switcher> pbase1_type;
|
||||
typedef boost::base_from_member<switcher, 1> pbase2_type;
|
||||
typedef boost::base_from_member<switcher, 2> pbase3_type;
|
||||
|
||||
typedef flow_regulator base1_type;
|
||||
typedef fan<6> base2_type;
|
||||
|
||||
public:
|
||||
system( double x );
|
||||
//...
|
||||
};
|
||||
|
||||
system::system( double x )
|
||||
: pbase0_type( 0.2 )
|
||||
, pbase1_type()
|
||||
, pbase2_type( -16, &this->pbase0_type::member.y )
|
||||
, pbase3_type( x, static_cast<int *>(NULL) )
|
||||
, base1_type( pbase3_type::member, pbase1_type::member )
|
||||
, base2_type( pbase2_type::member )
|
||||
{
|
||||
//...
|
||||
}
|
||||
|
||||
The final class has multiple sub-objects with the name `member`, so any
|
||||
use of that name needs qualification by a name of the appropriate base
|
||||
type. (Using `typedef`s ease mentioning the base types.) However, the fix
|
||||
introduces a new problem when a pointer is needed. Using the address
|
||||
operator with a sub-object qualified with its class's name results in a
|
||||
pointer-to-member (here, having a type of `an_int boost::base_from_member<
|
||||
an_int, 0> :: *`) instead of a pointer to the member (having a type of
|
||||
`an_int *`). The new problem is fixed by qualifying the sub-object with
|
||||
`this->` and is needed just for pointers, and not for references or values.
|
||||
|
||||
There are some argument conversions in the initialization. The constructor
|
||||
argument for `pbase0_type` is converted from `double` to `float`. The first
|
||||
constructor argument for `pbase2_type` is converted from `int` to `double`.
|
||||
The second constructor argument for `pbase3_type` is a special case of
|
||||
necessary conversion; all forms of the null-pointer literal in C++ (except
|
||||
`nullptr` from C++11) also look like compile-time integral expressions, so
|
||||
C++ always interprets such code as an integer when it has overloads that can
|
||||
take either an integer or a pointer. The last conversion is necessary for the
|
||||
compiler to call a constructor form with the exact pointer type used in
|
||||
`switcher`'s constructor. (If C++11's `nullptr` is used, it still needs a
|
||||
conversion if multiple pointer types can be accepted in a constructor call
|
||||
but `std::nullptr_t` cannot.)

[section Overview]
|
||||
|
||||
All of the contents of `<boost/compressed_pair.hpp>` are defined inside
|
||||
`namespace boost`.
|
||||
|
||||
The class `compressed_pair` is very similar to `std::pair`, but if either of
|
||||
the template arguments are empty classes, then the ['empty base-class
|
||||
optimisation] is applied to compress the size of the pair.
|
||||
|
||||
[endsect]

||||
|
||||
[section Synopsis]
|
||||
|
||||
template <class T1, class T2>
|
||||
class compressed_pair
|
||||
{
|
||||
public:
|
||||
typedef T1 first_type;
|
||||
typedef T2 second_type;
|
||||
typedef typename call_traits<first_type>::param_type first_param_type;
|
||||
typedef typename call_traits<second_type>::param_type second_param_type;
|
||||
typedef typename call_traits<first_type>::reference first_reference;
|
||||
typedef typename call_traits<second_type>::reference second_reference;
|
||||
typedef typename call_traits<first_type>::const_reference first_const_reference;
|
||||
typedef typename call_traits<second_type>::const_reference second_const_reference;
|
||||
|
||||
compressed_pair() : base() {}
|
||||
compressed_pair(first_param_type x, second_param_type y);
|
||||
explicit compressed_pair(first_param_type x);
|
||||
explicit compressed_pair(second_param_type y);
|
||||
|
||||
compressed_pair& operator=(const compressed_pair&);
|
||||
|
||||
first_reference first();
|
||||
first_const_reference first() const;
|
||||
|
||||
second_reference second();
|
||||
second_const_reference second() const;
|
||||
|
||||
void swap(compressed_pair& y);
|
||||
};
|
||||
|
||||
The two members of the pair can be accessed using the member functions
|
||||
`first()` and `second()`. Note that not all member functions can be
|
||||
instantiated for all template parameter types. In particular
|
||||
`compressed_pair` can be instantiated for reference and array types,
|
||||
however in these cases the range of constructors that can be used are
|
||||
limited. If types `T1` and `T2` are the same type, then there is only
|
||||
one version of the single-argument constructor, and this constructor
|
||||
initialises both values in the pair to the passed value.
|
||||
|
||||
Note that if either member is a POD type, then that member is not
|
||||
zero-initialized by the `compressed_pair` default constructor: it's up
|
||||
to you to supply an initial value for these types if you want them to have
|
||||
a default value.
|
||||
|
||||
Note that `compressed_pair` can not be instantiated if either of the
|
||||
template arguments is a union type, unless there is compiler support for
|
||||
`boost::is_union`, or if `boost::is_union` is specialised for the union
|
||||
type.
|
||||
|
||||
Finally, a word of caution for Visual C++ 6 users: if either argument is an
|
||||
empty type, then assigning to that member will produce memory corruption,
|
||||
unless the empty type has a "do nothing" assignment operator defined. This
|
||||
is due to a bug in the way VC6 generates implicit assignment operators.

[section Overview]
|
||||
[/===============]
|
||||
|
||||
The motivation for `declval` was introduced in [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2958.html#Value N2958:
|
||||
Moving Swap Forward]. Here follows a rewording of this chapter.
|
||||
|
||||
With the provision of decltype, late-specified return types, and default template-arguments for function templates a
|
||||
new generation of SFINAE patterns will emerge to at least partially compensate the lack of concepts on the C++0x timescale.
|
||||
Using this technique, it is sometimes necessary to obtain an object of a known type in a non-using context, e.g. given the declaration
|
||||
|
||||
template<class T>
|
||||
T&& declval(); // not used
|
||||
|
||||
as part of the function template declaration
|
||||
|
||||
template<class To, class From>
|
||||
decltype(static_cast<To>(declval<From>())) convert(From&&);
|
||||
|
||||
or as part of a class template definition
|
||||
|
||||
template<class> class result_of;
|
||||
|
||||
template<class Fn, class... ArgTypes>
|
||||
struct result_of<Fn(ArgTypes...)>
|
||||
{
|
||||
typedef decltype(declval<Fn>()(declval<ArgTypes>()...)) type;
|
||||
};
|
||||
|
||||
The role of the function template declval() is a transformation of a type T into a value without using or evaluating this function.
|
||||
The name is supposed to direct the reader's attention to the fact that the expression `declval<T>()` is an lvalue if and only if
|
||||
T is an lvalue-reference, otherwise an rvalue. To extend the domain of this function we can do a bit better by changing its declaration to
|
||||
|
||||
template<class T>
|
||||
typename std::add_rvalue_reference<T>::type declval(); // not used
|
||||
|
||||
which ensures that we can also use cv void as template parameter. The careful reader might have noticed that `declval()`
|
||||
already exists under the name create() as part of the definition of the semantics of the type trait is_convertible in the C++0x standard.
|
||||
|
||||
The provision of a new library component that allows the production of values in unevaluated expressions is considered
|
||||
important to realize constrained templates in C++0x where concepts are not available.
|
||||
This extremely light-weight function is expected to be part of the daily tool-box of the C++0x programmer.

`#include <boost/utility/declval.hpp>`
|
||||
|
||||
namespace boost {
|
||||
|
||||
template <typename T>
|
||||
typename add_rvalue_reference<T>::type declval() noexcept; // as unevaluated operand
|
||||
|
||||
} // namespace boost
|
||||
|
||||
|
||||
The library provides the function template declval to simplify the definition of expressions which occur as unevaluated operands.
|
||||
|
||||
template <typename T>
|
||||
typename add_rvalue_reference<T>::type declval();
|
||||
|
||||
[*Remarks:] If this function is used, the program is ill-formed.
|
||||
|
||||
[*Remarks:] The template parameter T of declval may be an incomplete type.
|
||||
|
||||
[*Example:]
|
||||
|
||||
template <class To, class From>
|
||||
decltype(static_cast<To>(declval<From>())) convert(From&&);
|
||||
|
||||
Declares a function template convert which only participates in overloading if the type From can be explicitly converted to type To.

[section Overview]
|
||||
[/===============]
|
||||
|
||||
Boost.StringRef is an implementation of Jeffrey Yaskin's [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3442.html N3442:
|
||||
string_ref: a non-owning reference to a string].
|
||||
|
||||
When you are parsing/processing strings from some external source, frequently you want to pass a piece of text to a procedure for specialized processing. The canonical way to do this is as a `std::string`, but that has certain drawbacks:
|
||||
|
||||
1) If you are processing a buffer of text (say a HTTP response or the contents of a file), then you have to create the string from the text you want to pass, which involves memory allocation and copying of data.
|
||||
|
||||
2) if a routine receives a constant `std::string` and wants to pass a portion of that string to another routine, then it must create a new string of that substring.
|
||||
|
||||
3) A routine receives a constant `std::string` and wants to return a portion of the string, then it must create a new string to return.
|
||||
|
||||
`string_ref` is designed to solve these efficiency problems. A `string_ref` is a read-only reference to a contiguous sequence of characters, and provides much of the functionality of `std::string`. A `string_ref` is cheap to create, copy and pass by value, because it does not actually own the storage that it points to.
|
||||
|
||||
A `string_ref` is implemented as a small struct that contains a pointer to the start of the character data and a count. A `string_ref` is cheap to create and cheap to copy.
|
||||
|
||||
`string_ref` acts as a container; it includes all the methods that you would expect in a container, including iteration support, `operator []`, `at` and `size`. It can be used with any of the iterator-based algorithms in the STL - as long as you don't need to change the underlying data (`sort` and `remove`, for example, will not work)
|
||||
|
||||
Besides generic container functionality, `string_ref` provides a subset of the interface of `std::string`. This makes it easy to replace parameters of type `const std::string &` with `boost::string_ref`. Like `std::string`, `string_ref` has a static member variable named `npos` to denote the result of failed searches, and to mean "the end".
|
||||
|
||||
Because a `string_ref` does not own the data that it "points to", it introduces lifetime issues into code that uses it. The programmer must ensure that the data that a `string_ref` refers to exists as long as the `string_ref` does.

|
||||
[section Examples]
|
||||
[/===============]
|
||||
|
||||
Integrating `string_ref` into your code is fairly simple. Wherever you pass a `const std::string &` or `std::string` as a parameter, that's a candidate for passing a `boost::string_ref`.
|
||||
|
||||
std::string extract_part ( const std::string &bar ) {
|
||||
return bar.substr ( 2, 3 );
|
||||
}
|
||||
|
||||
if ( extract_part ( "ABCDEFG" ).front() == 'C' ) { /* do something */ }
|
||||
|
||||
Let's figure out what happens in this (contrived) example.
|
||||
|
||||
First, a temporary string is created from the string literal `"ABCDEFG"`, and it is passed (by reference) to the routine `extract_part`. Then a second string is created in the call `std::string::substr` and returned to `extract_part` (this copy may be elided by RVO). Then `extract_part` returns that string back to the caller (again this copy may be elided). The first temporary string is deallocated, and `front` is called on the second string, and then it is deallocated as well.
|
||||
|
||||
Two `std::string`s are created, and two copy operations. That's (potentially) four memory allocations and deallocations, and the associated copying of data.
|
||||
|
||||
Now let's look at the same code with `string_ref`:
|
||||
|
||||
boost::string_ref extract_part ( boost::string_ref bar ) {
|
||||
return bar.substr ( 2, 3 );
|
||||
}
|
||||
|
||||
if ( extract_part ( "ABCDEFG" ).front() == "C" ) { /* do something */ }
|
||||
|
||||
No memory allocations. No copying of character data. No changes to the code other than the types. There are two `string_ref`s created, and two `string_ref`s copied, but those are cheap operations.

[section:reference Reference ]
|
||||
[/=================]
|
||||
|
||||
The header file "string_ref.hpp" defines a template `boost::basic_string_ref`, and four specializations - for `char` / `wchar_t` / `char16_t` / `char32_t` .
|
||||
|
||||
`#include <boost/utility/string_ref.hpp>`
|
||||
|
||||
Construction and copying:
|
||||
|
||||
BOOST_CONSTEXPR basic_string_ref (); // Constructs an empty string_ref
|
||||
BOOST_CONSTEXPR basic_string_ref(const charT* str); // Constructs from a NULL-terminated string
|
||||
BOOST_CONSTEXPR basic_string_ref(const charT* str, size_type len); // Constructs from a pointer, length pair
|
||||
template<typename Allocator>
|
||||
basic_string_ref(const std::basic_string<charT, traits, Allocator>& str); // Constructs from a std::string
|
||||
basic_string_ref (const basic_string_ref &rhs);
|
||||
basic_string_ref& operator=(const basic_string_ref &rhs);
|
||||
|
||||
`string_ref` does not define a move constructor nor a move-assignment operator because copying a `string_ref` is just a cheap as moving one.
|
||||
|
||||
Basic container-like functions:
|
||||
|
||||
BOOST_CONSTEXPR size_type size() const ;
|
||||
BOOST_CONSTEXPR size_type length() const ;
|
||||
BOOST_CONSTEXPR size_type max_size() const ;
|
||||
BOOST_CONSTEXPR bool empty() const ;
|
||||
|
||||
// All iterators are const_iterators
|
||||
BOOST_CONSTEXPR const_iterator begin() const ;
|
||||
BOOST_CONSTEXPR const_iterator cbegin() const ;
|
||||
BOOST_CONSTEXPR const_iterator end() const ;
|
||||
BOOST_CONSTEXPR const_iterator cend() const ;
|
||||
const_reverse_iterator rbegin() const ;
|
||||
const_reverse_iterator crbegin() const ;
|
||||
const_reverse_iterator rend() const ;
|
||||
const_reverse_iterator crend() const ;
|
||||
|
||||
Access to the individual elements (all of which are const):
|
||||
|
||||
BOOST_CONSTEXPR const charT& operator[](size_type pos) const ;
|
||||
const charT& at(size_t pos) const ;
|
||||
BOOST_CONSTEXPR const charT& front() const ;
|
||||
BOOST_CONSTEXPR const charT& back() const ;
|
||||
BOOST_CONSTEXPR const charT* data() const ;
|
||||
|
||||
Modifying the `string_ref` (but not the underlying data):
|
||||
|
||||
void clear();
|
||||
void remove_prefix(size_type n);
|
||||
void remove_suffix(size_type n);
|
||||
|
||||
Searching:
|
||||
|
||||
size_type find(basic_string_ref s) const ;
|
||||
size_type find(charT c) const ;
|
||||
size_type rfind(basic_string_ref s) const ;
|
||||
size_type rfind(charT c) const ;
|
||||
size_type find_first_of(charT c) const ;
|
||||
size_type find_last_of (charT c) const ;
|
||||
|
||||
size_type find_first_of(basic_string_ref s) const ;
|
||||
size_type find_last_of(basic_string_ref s) const ;
|
||||
size_type find_first_not_of(basic_string_ref s) const ;
|
||||
size_type find_first_not_of(charT c) const ;
|
||||
size_type find_last_not_of(basic_string_ref s) const ;
|
||||
size_type find_last_not_of(charT c) const ;
|
||||
|
||||
String-like operations:
|
||||
|
||||
BOOST_CONSTEXPR basic_string_ref substr(size_type pos, size_type n=npos) const ; // Creates a new string_ref
|
||||
bool starts_with(charT c) const ;
|
||||
bool starts_with(basic_string_ref x) const ;
|
||||
bool ends_with(charT c) const ;
|
||||
bool ends_with(basic_string_ref x) const ;

This library allows to wrap types within round parenthesis so they can always

be passed as macro parameters.

Consider the following macro which declares a variable named <code class="computeroutput"><span class="identifier">var</span></code><code class="literal"><span class="emphasis"><em>n</em></span></code>
|

with the specified <code class="literal"><span class="emphasis"><em>type</em></span></code> (see also

</p><p>
|
||||
The first macro invocation works correctly declaring a variable named <code class="computeroutput"><span class="identifier">var1</span></code> of type <code class="computeroutput"><span class="keyword">int</span></code>.
|
||||
However, the second macro invocation fails generating a preprocessor error
|
||||
similar to the following:
|
||||
</p><pre class="programlisting">error: macro "VAR" passed 3 arguments, but takes just 2
|
||||
</pre><p>
|
||||
That is because the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span></code> type passed as the first macro parameter
|
||||
contains a comma <code class="computeroutput"><span class="special">,</span></code> not wrapped
|
||||
by round parenthesis <code class="computeroutput"><span class="special">()</span></code>. The preprocessor
|
||||
interprets that unwrapped comma as a separation between macro parameters concluding
|
||||
that a total of three (and not two) parameters are passed to the macro in the
|
||||
following order:
|
||||
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
|
||||
<code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span><span class="special"><</span><span class="keyword">int</span></code>
|
||||
</li><li class="listitem">
|
||||
<code class="computeroutput"><span class="keyword">char</span><span class="special">></span></code>
|
||||
</li><li class="listitem">
|
||||
<code class="computeroutput"><span class="number">2</span></code>
|
||||
</li></ol></div><p>
|
||||
Note that, differently from the compiler, the preprocessor only recognizes
|
||||
round parenthesis <code class="computeroutput"><span class="special">()</span></code>. Angular
|
||||
<code class="computeroutput"><span class="special"><></span></code> and squared <code class="computeroutput"><span class="special">[]</span></code> parenthesis are not recognized by the preprocessor
|
||||
when parsing macro parameters.

|
||||
In some cases, it might be possible to workaround this issue by avoiding to
|
||||
pass the type expression to the macro all together. For example, in the case
|
||||
above a <code class="computeroutput"><span class="keyword">typedef</span></code> could have been
|
||||
used to specify the type expression with the commas outside the macro (see
|
||||
also <a href="../../test/var.cpp" target="_top"><code class="literal">var.cpp</code></a>):
|
||||
</p><p>
|
||||
</p><pre class="programlisting"><span class="keyword">typedef</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span><span class="special"><</span><span class="keyword">int</span><span class="special">,</span> <span class="keyword">char</span><span class="special">></span> <span class="identifier">map_type</span><span class="special">;</span>
|

<span class="identifier">VAR</span><span class="special">(</span><span class="identifier">map_type</span><span class="special">,</span> <span class="number">3</span><span class="special">);</span> <span class="comment">// OK.</span>

</p><p>
|

When this is neither possible nor desired (e.g., see the function template
|
||||
<code class="computeroutput"><span class="identifier">f</span></code> in the section below), this
|
||||
library header <code class="computeroutput"><a class="link" href="#header.boost.utility.identity_type_hpp" title="Header <boost/utility/identity_type.hpp>">boost/utility/identity_type.hpp</a></code>

defines a macro <code class="computeroutput"><a class="link" href="#BOOST_IDENTITY_TYPE" title="Macro BOOST_IDENTITY_TYPE">BOOST_IDENTITY_TYPE</a></code>
|
||||
which can be used to workaround the issue while keeping the type expression
|

as one of the macro parameters (see also <a href="../../test/var.cpp" target="_top"><code class="literal">var.cpp</code></a>).

The <code class="computeroutput"><a class="link" href="#BOOST_IDENTITY_TYPE" title="Macro BOOST_IDENTITY_TYPE">BOOST_IDENTITY_TYPE</a></code> macro
|
||||
expands to an expression that evaluates (at compile-time) to the specified
|
||||
type. The specified type is never split into multiple macro parameters because
|
||||
it is always wrapped by a set of extra round parenthesis <code class="computeroutput"><span class="special">()</span></code>.
|
||||
In fact, a total of two sets of round parenthesis must be used: The parenthesis
|
||||
to invoke the macro <code class="computeroutput"><span class="identifier">BOOST_IDENTITY_TYPE</span><span class="special">(...)</span></code> plus the inner parenthesis to wrap the
|

type passed to the macro <code class="computeroutput"><span class="identifier">BOOST_IDENTITY_TYPE</span><span class="special">((...))</span></code>.

when the <code class="computeroutput"><a class="link" href="#BOOST_IDENTITY_TYPE" title="Macro BOOST_IDENTITY_TYPE">BOOST_IDENTITY_TYPE</a></code>

On some compilers (e.g., GCC), using this macro on abstract types (i.e., classes

with one or more pure virtual functions) generates a compiler error. This can

be avoided by manipulating the type adding and removing a reference to it.

Let's program a macro that performs a static assertion on a <a href="http://en.wikipedia.org/wiki/Template_metaprogramming" target="_top">Template

to pass a meta-function with multiple template parameters to the assert macro
|

(so to handle the commas separating the template parameters). In this case,

if the meta-function is an abstract type, it needs to be manipulated adding

Essentially, the type is wrapped between round parenthesis <code class="computeroutput"><span class="special">(</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span><span class="special"><</span><span class="keyword">int</span><span class="special">,</span>

|

so it can be passed as a single macro parameter even if it contains commas.
|
||||
Then the parenthesized type is transformed into the type of a function returning
|
||||
<code class="computeroutput"><span class="keyword">void</span></code> and with the specified type
|
||||
as the type of the first and only argument <code class="computeroutput"><span class="keyword">void</span>

Finally, the type of the first argument
|

<code class="computeroutput"><span class="identifier">arg1_type</span></code> is extracted at compile-time
|

using the <code class="computeroutput"><span class="identifier">function_traits</span></code> meta-function
|

therefore obtaining the original type from the parenthesized type (effectively

stripping the extra parenthesis from around the specified type).

This library allows to wrap types within round parenthesis so they can always be passed as macro parameters.
|
||||
|
||||
[import ../test/var_error.cpp]
|
||||
[import ../test/var.cpp]
|
||||
[import ../test/template.cpp]
|
||||
[import ../test/abstract.cpp]
|
||||
[import ../test/paren.cpp]
|
||||
|
||||
[section Motivation]
|
||||
|
||||
Consider the following macro which declares a variable named `var`[^['n]] with the specified [^['type]] (see also [@../../test/var_error.cpp =var_error.cpp=]):
|
||||
|
||||
[var_error]
|
||||
|
||||
The first macro invocation works correctly declaring a variable named `var1` of type `int`.
|
||||
However, the second macro invocation fails generating a preprocessor error similar to the following:
|
||||
|
||||
[pre
|
||||
error: macro "VAR" passed 3 arguments, but takes just 2
|
||||
]
|
||||
|
||||
That is because the `std::map` type passed as the first macro parameter contains a comma `,` not wrapped by round parenthesis `()`.
|
||||
The preprocessor interprets that unwrapped comma as a separation between macro parameters concluding that a total of three (and not two) parameters are passed to the macro in the following order:
|
||||
|
||||
# `std::map<int`
|
||||
# `char>`
|
||||
# `2`
|
||||
|
||||
Note that, differently from the compiler, the preprocessor only recognizes round parenthesis `()`.
|
||||
Angular `<>` and squared `[]` parenthesis are not recognized by the preprocessor when parsing macro parameters.
|
||||
|
||||
[endsect]
|
||||
|
||||
[section Solution]
|
||||
|
||||
In some cases, it might be possible to workaround this issue by avoiding to pass the type expression to the macro all together.
|
||||
For example, in the case above a `typedef` could have been used to specify the type expression with the commas outside the macro (see also [@../../test/var.cpp =var.cpp=]):
|
||||
|
||||
[var_typedef]
|
||||
|
||||
When this is neither possible nor desired (e.g., see the function template `f` in the section below), this library header [headerref boost/utility/identity_type.hpp] defines a macro [macroref BOOST_IDENTITY_TYPE] which can be used to workaround the issue while keeping the type expression as one of the macro parameters (see also [@../../test/var.cpp =var.cpp=]).
|
||||
|
||||
[var_ok]
|
||||
|
||||
The [macroref BOOST_IDENTITY_TYPE] macro expands to an expression that evaluates (at compile-time) to the specified type.
|
||||
The specified type is never split into multiple macro parameters because it is always wrapped by a set of extra round parenthesis `()`.
|
||||
In fact, a total of two sets of round parenthesis must be used: The parenthesis to invoke the macro `BOOST_IDENTITY_TYPE(...)` plus the inner parenthesis to wrap the type passed to the macro `BOOST_IDENTITY_TYPE((...))`.
|
||||
|
||||
This macro works on any [@http://www.open-std.org/JTC1/SC22/WG21/docs/standards C++03] compiler (and it does not use [@http://en.wikipedia.org/wiki/Variadic_macro variadic macros]).
|
||||
[footnote
|
||||
Using variadic macros, it would be possible to require a single set of extra parenthesis `BOOST_IDENTITY_TYPE(`[^['type]]`)` instead of two `BOOST_IDENTITY_TYPE((`[^['type]]`))` but variadic macros are not part of C++03 (even if nowadays they are supported by most modern compilers and they are also part of C++11).
|
||||

|
||||
The authors originally developed and tested this library using GNU Compiler Collection (GCC) C++ 4.5.3 (with and without C++11 features enabled `-std=c++0x`) on Cygwin and Miscrosoft Visual C++ (MSVC) 8.0 on Windows 7.
|
||||
See the library [@http://www.boost.org/development/tests/release/developer/utility-identity_type.html regressions test results] for more information on supported compilers and platforms.
|
||||
|
||||
[endsect]
|
||||
|
||||
[section Templates]
|
||||
|
||||
This macro must be prefixed by `typename` when used within templates.
|
||||
For example, let's program a macro that declares a function parameter named `arg`[^['n]] with the specified [^['type]] (see also [@../../test/template.cpp =template.cpp=]):
|
||||
|
||||
[template_f_decl]
|
||||
[template_f_call]
|
||||
|
||||
However, note that the template parameter `char` must be manually specified when invoking the function as in `f<char>(a)`.
|
||||
In fact, when the [macroref BOOST_IDENTITY_TYPE] macro is used to wrap a function template parameter, the template parameter can no longer be automatically deduced by the compiler form the function call as `f(a)` would have done.
|
||||
[footnote
|
||||
This is because the implementation of [macroref BOOST_IDENTITY_TYPE] wraps the specified type within a meta-function.
|
||||
]
|
||||
(This limitation does not apply to class templates because class template parameters must always be explicitly specified.)
|
||||
In other words, without using the [macroref BOOST_IDENTITY_TYPE] macro, C++ would normally be able to automatically deduce the function template parameter as shown below:
|
||||
|
||||
[template_g_decl]
|
||||
[template_g_call]
|
||||
|
||||
[endsect]
|
||||
|
||||
[section Abstract Types]
|
||||
|
||||
On some compilers (e.g., GCC), using this macro on abstract types (i.e., classes with one or more pure virtual functions) generates a compiler error.
|
||||
This can be avoided by manipulating the type adding and removing a reference to it.
|
||||
|
||||
Let's program a macro that performs a static assertion on a [@http://en.wikipedia.org/wiki/Template_metaprogramming Template Meta-Programming] (TMP) meta-function (similarly to Boost.MPL [@http://www.boost.org/doc/libs/1_36_0/libs/mpl/doc/refmanual/assert.html `BOOST_MPL_ASSERT`]).
|
||||
The [macroref BOOST_IDENTITY_TYPE] macro can be used to pass a meta-function with multiple template parameters to the assert macro (so to handle the commas separating the template parameters).
|
||||
In this case, if the meta-function is an abstract type, it needs to be manipulated adding and removing a reference to it (see also [@../../test/abstract.cpp =abstract.cpp=]):
|
||||
|
||||
[abstract]
|
||||
|
||||
[endsect]
|
||||
|
||||
[section Annex: Usage]
|
||||
|
||||
The [macroref BOOST_IDENTITY_TYPE] macro can be used either when calling a user-defined macro (as shown by the examples so far), or internally when implementing a user-defined macro (as shown below).
|
||||
When [macroref BOOST_IDENTITY_TYPE] is used in the implementation of the user-defined macro, the caller of the user macro will have to specify the extra parenthesis (see also [@../../test/paren.cpp =paren.cpp=]):
|
||||
|
||||
[paren]
|
||||
|
||||
However, note that the caller will /always/ have to specify the extra parenthesis even when the macro parameters contain no comma:
|
||||
|
||||
[paren_always]
|
||||
|
||||
In some cases, using [macroref BOOST_IDENTITY_TYPE] in the implementation of the user-defined macro might provide the best syntax for the caller.
|
||||
For example, this is the case for `BOOST_MPL_ASSERT` because the majority of template meta-programming expressions contain unwrapped commas so it is less confusing for the user to always specify the extra parenthesis `((...))` instead of using [macroref BOOST_IDENTITY_TYPE]:
|
||||
|
||||
BOOST_MPL_ASSERT(( // Natural syntax.
|
||||
boost::mpl::and_<
|
||||
boost::is_const<T>
|
||||
, boost::is_reference<T>
|
||||
>
|
||||
));
|
||||
|
||||
However, in other situations it might be preferable to not require the extra parenthesis in the common cases and handle commas as special cases using [macroref BOOST_IDENTITY_TYPE].
|
||||
For example, this is the case for [@http://www.boost.org/libs/local_function `BOOST_LOCAL_FUNCTION`] for which always requiring the extra parenthesis `((...))` around the types would lead to an unnatural syntax for the local function signature:
|
||||
|
||||
int BOOST_LOCAL_FUNCTION( ((int&)) x, ((int&)) y ) { // Unnatural syntax.
|
||||
return x + y;
|
||||
} BOOST_LOCAL_FUNCTION_NAME(add)
|
||||
|
||||
Instead requiring the user to specify [macroref BOOST_IDENTITY_TYPE] only when needed allows for the more natural syntax `BOOST_LOCAL_FUNCTION(int& x, int& y)` in the common cases when the parameter types contain no comma (while still allowing to specify parameter types with commas as special cases using `BOOST_LOCAL_FUNCTION(BOOST_IDENTITY_TYPE((std::map<int, char>))& x, int& y)`).

|
||||
The implementation of this library macro is equivalent to the following:
|
||||
[footnote
|
||||
There is absolutely no guarantee that the macro is actually implemented using the code listed in this documentation.
|
||||
The listed code is for explanatory purposes only.

#include <boost/type_traits/function_traits.hpp>
|
||||
|
||||
#define BOOST_IDENTITY_TYPE(parenthesized_type) \
|
||||
boost::function_traits<void parenthesized_type>::arg1_type
|
||||
|
||||
Essentially, the type is wrapped between round parenthesis `(std::map<int, char>)` so it can be passed as a single macro parameter even if it contains commas.
|
||||
Then the parenthesized type is transformed into the type of a function returning `void` and with the specified type as the type of the first and only argument `void (std::map<int, char>)`.
|
||||
Finally, the type of the first argument `arg1_type` is extracted at compile-time using the `function_traits` meta-function therefore obtaining the original type from the parenthesized type (effectively stripping the extra parenthesis from around the specified type).

<p>Suppose we have a class</p>
|
||||
<pre>struct X
|
||||
{
|
||||
X ( int, std::string ) ;
|
||||
} ;</pre>
|
||||
<p>And a container for it which supports an empty state (that is, which can contain zero objects):</p>
|
||||
<pre>struct C
|
||||
{
|
||||
C() : contained_(0) {}
|
||||
~C() { delete contained_ ; }
|
||||
X* contained_ ;
|
||||
} ;</pre>
|
||||
<p>A container designed to support an empty state typically doesn't require the contained type to be DefaultConstructible,
|
||||
but it typically requires it to be CopyConstructible as a mechanism to
|
||||
initialize the object to store:</p>
|
||||
<pre>struct C
|
||||
{
|
||||
C() : contained_(0) {}
|
||||
C ( X const& v ) : contained_ ( new X(v) ) {}
|
||||
~C() { delete contained_ ; }
|
||||
X* contained_ ;
|
||||
} ;</pre>
|
||||
<p>There is a subtle problem with this: since the mechanism used to initialize the stored object is copy construction,
|
||||
there must exist a previously constructed source object to copy from. This
|
||||
object is likely to be temporary and serve no purpose besides being the source</p>
|
||||
<pre>void foo()
|
||||
{
|
||||
// Temporary object created.
|
||||
C c( X(123,"hello") ) ;
|
||||
}
|
||||
</pre>
|
||||
<p>A solution to this problem is to support direct construction of the contained
|
||||
object right in the container's storage.<br>
|
||||
In this scheme, the user supplies the arguments for the X constructor
|
||||
directly to the container:</p>
|
||||
<pre>struct C
|
||||
{
|
||||
C() : contained_(0) {}
|
||||
C ( X const& v ) : contained_ ( new X(v) ) {}
|
||||
C ( int a0, std::string a1 ) : contained_ ( new X(a0,a1) ) {}
|
||||
~C() { delete contained_ ; }
|
||||
X* contained_ ;
|
||||
} ;</pre>
|
||||
<pre>void foo()
|
||||
{
|
||||
// Wrapped object constructed in-place
|
||||
// No temporary created.
|
||||
C c(123,"hello") ;
|
||||
}
|
||||
</pre>
|
||||
<p>Clearly, this solution doesn't scale well since the container must duplicate all the constructor overloads from the contained type
|
||||
(at least all those which are to be supported directly in the container).</p>
|
||||
|
||||
<H2><A NAME="framework"></A>Framework</H2>
|
||||
<p>
|
||||
This library proposes a framework to allow some containers to directly contruct contained objects in-place without requiring
|
||||
the entire set of constructor overloads from the contained type. It also allows the container to remove the CopyConstuctible
|
||||
requirement from the contained type since objects can be directly constructed in-place without need of a copy.<br>
|
||||
The only requirement on the container is that it must provide proper storage (that is, correctly aligned and sized).
|
||||
Naturally, the container will typically support uninitialized storage to avoid the in-place construction to override
|
||||
a fully-constructed object (as this would defeat the purpose of in-place construction)
|
||||
</p>
|
||||
<p>For this purpose, the framework provides two families of classes collectively called: InPlaceFactories and TypedInPlaceFactories.<br>
|
||||
Essentially, these classes hold a sequence of actual parameters and a method to contruct an object in place using these parameters.
|
||||
Each member of the family differs only in the number (and type) of the parameter list. The first family
|
||||
takes the type of the object to construct directly in method provided for that
|
||||
purpose, whereas the second family incorporates that type in the factory class
|
||||
itself..</p>
|
||||
<p>From the container POV, using the framework amounts to calling the factory's method to contruct the object in place.
|
||||
From the user POV, it amounts to creating the right factory object to hold the parameters and pass it to the container.<br>
|
||||
The following simplified example shows the basic idea. A complete example follows the formal specification of the framework:</p>
|
||||
<pre>struct C
|
||||
{
|
||||
template<class InPlaceFactory>
|
||||
C ( InPlaceFactory const& aFactory )
|
||||
:
|
||||
contained_ ( uninitialized_storage() )
|
||||
{
|
||||
aFactory.template apply<X>(contained_);
|
||||
}
|
||||
|
||||
~C()
|
||||
{
|
||||
contained_ -> X::~X();
|
||||
delete[] contained_ ;
|
||||
}
|
||||
|
||||
char* uninitialized_storage() { return new char[sizeof(X)] ; }
|
||||
|
||||
char* contained_ ;
|
||||
} ;
|
||||
|
||||
void foo()
|
||||
{
|
||||
C c( in_place(123,"hello") ) ;
|
||||
}

|

|
||||
<p>The following is the first member of the family of 'in_place_factory' classes, along with its corresponding helper template function.
|
||||
The rest of the family varies only in the number and type of template (and constructor) parameters.</p>
|
||||
<PRE>namespace boost {
|
||||
|
||||
struct in_place_factory_base {} ;
|

}

</PRE>
|
||||
|
||||
<p>Similarly, the following is the first member of the family of 'typed_in_place_factory' classes, along with its corresponding
|
||||
helper template function. The rest of the family varies only in the number and type of template (and constructor) parameters.</p>
|
||||
<PRE>namespace boost {
|
||||
|
||||
struct typed_in_place_factory_base {} ;
|
||||
|
||||
template<class T, class A0>
|
||||
class typed_in_place_factory : public typed_in_place_factory_base
|

{

public:</PRE>

return typed_in_place_factory<T,A0>(a0);

}</PRE>

<PRE>}
|

</PRE>
|
||||
|
||||
<p>As you can see, the 'in_place_factory' and 'typed_in_place_factory' template classes varies only in the way they specify
|
||||
the target type: in the first family, the type is given as a template argument to the apply member function while in the
|
||||
second it is given directly as part of the factory class.<br>
|
||||
When the container holds a unique non-polymorphic type (such as the case of Boost.Optional), it knows the exact dynamic-type
|
||||
of the contained object and can pass it to the apply() method of a (non-typed) factory.
|
||||
In this case, end users can use an 'in_place_factory' instance which can be constructed without the type of the object to construct.<br>
|
||||
However, if the container holds heterogeneous or polymorphic objects (such as the case of Boost.Variant), the dynamic-type
|
||||
of the object to be constructed must be known by the factory itslef. In this case, end users must use a 'typed_in_place_factory'
|
||||
instead.</p>

<p>As shown in the introductory simplified example, the container class must
|
||||
contain methods that accept an instance of
|
||||
these factories and pass the object's storage to the factory's apply method.<br>
|
||||
However, the type of the factory class cannot be completly specified in the container class because that would
|
||||
defeat the whole purpose of the factories which is to allow the container to accept a variadic argument list
|
||||
for the constructor of its contained object.<br>
|
||||
The correct function overload must be based on the only distinctive and common
|
||||
characteristic of all the classes in each family, the base class.<br>
|
||||
Depending on the container class, you can use 'enable_if' to generate the right overload, or use the following
|
||||
dispatch technique (used in the Boost.Optional class):
|
||||
</p>
|
||||
<pre>struct C
|
||||
{
|
||||
C() : contained_(0) {}
|
||||
C ( X const& v ) : contained_ ( new X(v) ) {}
|
||||
|
||||
template<class Expr>
|
||||
C ( Expr const& expr )
|
||||
:
|
||||
contained_ ( uninitialized_storage() )
|
||||
{
|
||||
construct(expr,&expr)
|
||||
}
|
||||
|
||||
~C() { delete contained_ ; }
|
||||
|
||||
template<class InPlaceFactory>
|
||||
void construct ( InPlaceFactory const& aFactory, boost::in_place_factory_base* )
|
||||
{
|
||||
aFactory.template apply<X>(contained_);
|
||||
}
|
||||
|
||||
template<class TypedInPlaceFactory>
|
||||
void construct ( TypedInPlaceFactory const& aFactory, boost::typed_in_place_factory_base* )
|
||||
{
|
||||
aFactory.apply(contained_);
|
||||
}
|
||||
|
||||
X* uninitialized_storage() { return static_cast<X*>(new char[sizeof(X)]) ; }
|
||||
|
||||
X* contained_ ;
|
||||
} ;
|
||||
</pre>

|

|
||||
<h2><A NAME="user-usage">User-side Usage</a></h2>
|
||||
|
||||
<p>End users pass to the container an instance of a factory object holding the actual parameters needed to construct the
|
||||
contained object directly within the container. For this, the helper template function 'in_place' is used.<br>
|
||||
The call 'in_place(a0,a1,a2,...,an)' constructs a (non-typed) 'in_place_factory' instance with the given argument list.<br>
|
||||
The call 'in_place<T>(a0,a1,a2,...,an)' constructs a 'typed_in_place_factory' instance with the given argument list for the
|
||||
type 'T'.</p>
|
||||
<pre>void foo()
|
||||
{
|
||||
C a( in_place(123,"hello") ) ; // in_place_factory passed
|
||||
C b( in_place<X>(456,"world") ) ; // typed_in_place_factory passed
|
||||
}

// (Matthew Bradbury, fixes #4432)
|

// 03 Apr 08 Make sure "convertible to bool" is sufficient
|

// for T::operator<, etc. (Daniel Frey)
|

// 24 May 07 Changed empty_base to depend on T, see
|
||||
// http://svn.boost.org/trac/boost/ticket/979
|
||||
// 21 Oct 02 Modified implementation of operators to allow compilers with a
|

// correct named return value optimization (NRVO) to produce optimal
|
||||
// code. (Daniel Frey)
|
||||
// 02 Dec 01 Bug fixed in random_access_iteratable. (Helmut Zeisel)
|
||||
// 28 Sep 01 Factored out iterator operator groups. (Daryle Walker)
|

// workaround for empty base class optimization
|

// parameters, added support for self-proxying, additional
|
||||
// documentation and tests (Aleksey Gurtovoy)
|
||||
// 29 May 01 Added operator classes for << and >>. Added input and output
|
||||
// iterator helper classes. Added classes to connect equality and
|
||||
// relational operators. Added classes for groups of related

// operators. Reimplemented example operator and iterator helper
|

// 12 Nov 99 Add operators templates (Ed Brey)
|
||||
// 11 Nov 99 Add single template parameter version for compilers without
|
||||
// partial specialization (Beman Dawes)
|
||||
// 10 Nov 99 Initial version
|
||||
|
||||
// 10 Jun 00:
|
||||
// An additional optional template parameter was added to most of
|
||||
// operator templates to support the base class chaining technique (see
|
||||
// documentation for the details). Unfortunately, a straightforward
|
||||
// implementation of this change would have broken compatibility with the
|
||||
// previous version of the library by making it impossible to use the same
|
||||
// template name (e.g. 'addable') for both the 1- and 2-argument versions of
|
||||
// an operator template. This implementation solves the backward-compatibility
|
||||
// issue at the cost of some simplicity.
|
||||
//
|
||||
// One of the complications is an existence of special auxiliary class template
|
||||
// 'is_chained_base<>' (see 'detail' namespace below), which is used
|
||||
// to determine whether its template parameter is a library's operator template
|
||||
// or not. You have to specialize 'is_chained_base<>' for each new
|
||||
// operator template you add to the library.
|
||||
//
|
||||
// However, most of the non-trivial implementation details are hidden behind
|
||||
// several local macros defined below, and as soon as you understand them,
|
||||
// you understand the whole library implementation.

The following code works by converting the input bit pattern into a
|
||||
Boost.Preprocessor sequence, then converting groupings of 3 bits each into
|
||||
the corresponding octal digit, and finally concatenating all of the digits
|
||||
together along with a leading zero. This yields a standard octal literal
|
||||
with the desired value as specified in bits.

/**

@brief This macro allows to wrap the specified type expression within extra
|

round parenthesis so the type can be passed as a single macro parameter even if
|
||||
it contains commas (not already wrapped within round parenthesis).
|
||||
|
||||
@Params
|
||||
@Param{parenthesized_type,
|
||||
The type expression to be passed as macro parameter wrapped by a single set
|
||||
of round parenthesis <c>(...)</c>.
|
||||
This type expression can contain an arbitrary number of commas.
|
||||
}
|
||||
@EndParams
|
||||
|
||||
This macro works on any C++03 compiler (it does not use variadic macros).
|
||||
|
||||
This macro must be prefixed by <c>typename</c> when used within templates.
|
||||
Note that the compiler will not be able to automatically determine function
|
||||
template parameters when they are wrapped with this macro (these parameters
|
||||
need to be explicitly specified when calling the function template).
|
||||
|
||||
On some compilers (like GCC), using this macro on abstract types requires to
|
||||
add and remove a reference to the specified type.

<h3><a name="iterator_adaptors">The Iterator Adaptors Class</a></h3>
|
||||
|
||||
Implementing standard conforming iterators is a non-trivial task.
|
||||
There are some fine-points such as iterator/const_iterator
|
||||
interactions and there are the myriad of operators that should be
|
||||
implemented but are easily forgotten such as
|
||||
<tt>operator->()</tt>. The purpose of the
|
||||
<tt>iterator_adaptors</tt> class is to make it easier to implement an
|
||||
iterator class, and even easier to extend and adapt existing iterator
|
||||
types. The <tt>iterator_adaptors</tt> class itself is not an adaptor
|
||||
class but a <i>type generator</i>. It generates a pair of adaptor classes,
|
||||
one class for the mutable iterator and one class for the const
|
||||
iterator. The definition of the <tt>iterator_adaptors</tt> class is as
|
||||
follows:

||||
|
||||

||||

class Policies = default_iterator_policies>
|
||||
struct iterator_adaptors
|
||||
{
|

typedef ... iterator;
|
||||
typedef ... const_iterator;
|
||||
};
|
||||
</PRE></TD></TABLE>
|
||||
|
||||
<p>The <tt>Iterator</tt> and <tt>ConstIterator</tt> template parameters
|
||||
are the iterator types that you want to adapt. The <tt>Traits</tt> and
|
||||
<tt>ConstTraits</tt> must be iterator traits classes. The traits
|
||||
parameters default to the specialization of the
|
||||
<tt>std::iterator_traits</tt> class for the adapted iterators. If you
|
||||
want the traits for your new iterator adaptor (<tt>value_type</tt>,
|
||||
<tt>iterator_category</tt>, etc.) to be the same as the adapted
|
||||
iterator then use the default, otherwise create your own traits
|
||||
classes and pass them in <a href="#1">[1]</a>.
|
||||
|
||||
|
||||
<p>The <tt>Policies</tt> class that you pass in will become the heart of
|
||||
the iterator adaptor. The policy class determines how your new adaptor
|
||||
class will behave. The <tt>Policies</tt> class must implement 3, 4, or
|
||||
7 of the core iterator operations depending on whether you wish the
|
||||
new iterator adaptor class to be a
|
||||
<a href="http://www.sgi.com/Technology/STL/ForwardIterator.html">
|
||||
ForwardIterator</a>,
|
||||
<a href="http://www.sgi.com/Technology/STL/BidirectionalIterator.html">
|
||||
BidirectionalIterator</a>, or <a
|
||||
href="http://www.sgi.com/Technology/STL/RandomAccessIterator.html">
|
||||
RandomAccessIterator</a>. Make sure that the
|
||||
<tt>iterator_category</tt> type of the traits class you pass in
|
||||
matches the category of iterator that you want to create. The default
|
||||
policy class, <tt>default_iterator_policies</tt>, implements all 7 of
|
||||
the core operations in the usual way. If you wish to create an
|
||||
iterator adaptor that only changes a few of the iterator's behaviors,
|
||||
then you can have your new policy class inherit from
|
||||
<tt>default_iterator_policies</tt> to avoid retyping the usual
|
||||
behaviours. You should also look at <tt>default_iterator_policies</tt>
|
||||
as the "boiler-plate" for your own policy classes. The

||||
following is definition of the <tt>default_iterator_policies</tt>

<h3><a name="iterator_adaptor">The Iterator Adaptor Class</a></h3>
|
||||
|
||||
This is the class used inside of the <tt>iterator_adaptors</tt> type
|
||||
generator. Use this class directly (instead of using
|
||||
<tt>iterator_adaptors</tt>) when there is no difference between the
|
||||
const and non-const versions of the iterator type. Often this is
|
||||
because there is only a const (read-only) version of the iterator, as
|
||||
is the case for <tt>std::set</tt>'s iterators. Use the same type for
|
||||
the <tt>Iterator</tt> and <tt>NonconstIterator</tt> template
|
||||
arguments.

<p>
|

Next we will look at some iterator adaptors that are examples of how
|
||||
to use the iterator adaptors class, and that are useful iterator
|
||||
adaptors in their own right.
|
||||
|
||||
<h3><a name="transform_iterator">The Transform Iterator Class</a></h3>
|
||||
|
||||
It is often useful to automatically apply some function to the value
|
||||
returned by dereferencing (<tt>operator*()</tt>) an iterator. The
|
||||
<tt>transform_iterators</tt> class makes it easy to create an iterator
|
||||
adaptor that does just that.
|
||||
|
||||
First let us consider what the <tt>Policies</tt> class for the transform
|
||||
iterator should look like. We are only changing one of the iterator
|
||||
behaviours, so we will inherit from
|
||||
<tt>default_iterator_policies</tt>. In addition, we will need a
|
||||
function object to apply, so we will have a template parameter and a
|
||||
data member for the function object. The function will take one
|
||||
argument (the dereferenced value) and we will need to know the
|
||||
<tt>result_type</tt> of the function, so <a
|
||||
href="http://www.sgi.com/Technology/STL/AdaptableUnaryFunction.html">
|
||||
AdaptableUnaryFunction</a> is the corrent concept to choose for the
|
||||
function object type. Now for the heart of our iterator adaptor, we
|
||||
implement the <tt>dereference</tt> method, applying the function
|
||||
object to <tt>*i</tt>. The <tt>type<Reference></tt> class is
|
||||
there to tell you what the reference type of the iterator is, which is
|
||||
handy when writing generic iterator adaptors such as this one <a
|
||||
href="#2">[2]</a>.
|
||||
|
||||

||||

||||
<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>

<PRE>
|
||||
template <class AdaptableUnaryFunction>
|
||||
struct transform_iterator_policies : public default_iterator_policies
|
||||
{
|
||||
transform_iterator_policies(const AdaptableUnaryFunction& f) : m_f(f) { }
|
||||
|
||||
template <class Reference, class Iterator>
|
||||
Reference dereference(type<Reference>, const Iterator& i) const
|
||||
{ return m_f(*i); }
|
||||
|
||||
AdaptableUnaryFunction m_f;
|
||||
};
|
||||
</PRE></TD></TABLE>
|
||||
|
||||
Next we need to create the traits class for our new iterator. In some
|
||||
situations you may need to create a separate traits class for the
|
||||
const and non-const iterator types, but here a single traits class
|
||||
will do. The <tt>value_type</tt> and <tt>reference</tt> type of our
|
||||
transform iterator will be the <tt>result_type</tt> of the function
|
||||
object. The <tt>difference_type</tt> and <tt>iterator_category</tt>
|
||||
will be the same as the adapted iterator.
|
||||

||||

template <class AdaptableUnaryFunction, class IteratorTraits>
|
||||
struct transform_iterator_traits {
|

typedef typename AdaptableUnaryFunction::result_type value_type;
|
||||
typedef value_type reference;
|
||||
typedef value_type* pointer;
|
||||
typedef typename IteratorTraits::difference_type difference_type;
|
||||
typedef typename IteratorTraits::iterator_category iterator_category;
|
||||
};
|
||||
</PRE></TD></TABLE>
|
||||
|
||||
The final step is to use the <tt>iterator_adaptor</tt> class to
|
||||
construct our transform iterator. We will use the single iterator
|
||||
adaptor version because we will not need to create both a mutable and
|
||||
const version of the transform iterator. The transform iterator is
|
||||
inherently a read-only iterator. The nicest way to package up our new
|
||||
transform iterator is to create a type generator similar to
|
||||
<tt>iterator_adaptor</tt>. The first template parameter will be the
|
||||
type of the function object. The second parameter will be the adapted
|
||||
iterator type. The third parameter is the trait class for
|
||||
the adapted iterator. Inside the <tt>transform_iterators</tt> class
|
||||
we use the <tt>transform_iterator_traits</tt> class defined above to
|
||||
create the traits class for the new transform iterator. We then use
|
||||
the <tt>iterator_adaptor</tt> class to extract the generated
|
||||
iterator adaptor type.

<h3><a name="indirect_iterators">The Indirect Iterators Class</a></h3>
|

|

It is not all that uncommon to create data structures that consist of
|
||||
pointers to pointers. For such a structure it might be nice to have an
|
||||
iterator that applies a double-dereference inside the
|
||||
<tt>operator*()</tt>. The implementation of this is similar to the
|
||||
<tt>transform_iterators</tt><a href="#3">[3]</a>. We first create a
|
||||
policies class which does a double-dereference in the
|
||||
<tt>dereference()</tt> method. We then create a traits class, this
|
||||
time also including a template parameter for the traits of the second
|
||||
level iterators as well as the first. Lastly we wrap this up in the
|
||||
type generator <tt>indirect_iterators</tt>, using
|
||||
<tt>iterator_adaptors</tt> to do most of the work.

<h3><a name="reverse_iterators">The Reverse Iterators Class</a></h3>

Yes, there is already a <tt>reverse_iterator</tt> adaptor class

defined in the C++ Standard, but using the <tt>iterator_adaptors</tt>
|

class we can re-implement this classic adaptor in a more succinct and

elegant fashion. Also, this makes for a good example of using

<p>
|

The first step is to create the <tt>Policies</tt> class. As in the
|
||||
<tt>std::reverse_iterator</tt> class, we need to flip all the
|
||||
operations of the iterator. Increment will become decrement, advancing
|
||||
by <tt>n</tt> will become retreating by <tt>n</tt>, etc.

Since the traits of the reverse iterator adaptor will be the same as
|

the adapted iterator's traits, we do not need to create new traits
|

classes as was the case for <tt>transform_iterator</tt>. We can skip to
|

the final stage of creating a type generator class for our reverse
|

iterators using the <tt>iterator_adaptor</tt> class.

<h3><a name="integer_range">The Integer Range Class</a></h3>
|
||||
|
||||
The <tt>iterator_adaptors</tt> class can not only be used for adapting
|
||||
iterators, but it can also be used to take a non-iterator type and use
|
||||
it to build an iterator. An especially simple example of this is
|
||||
turning an integer type into an iterator, a counting iterator. The
|
||||
builtin integer types of C++ are almost iterators. They have
|
||||
<tt>operator++()</tt>, <tt>operator--()</tt>, etc. The one operator
|
||||
they are lacking is the <tt>operator*()</tt>, which we will want to
|
||||
simply return the current value of the integer. The following few
|
||||
lines of code implement the policy and traits class for the counting
|
||||
iterator.

Typically we will want to count the integers in some range, so a nice
|
||||
interface would be to have a fake container that represents the range
|
||||
of integers. The following is the definition of such a class called
|
||||
<tt>integer_range</tt>.

<h3>Challenge</h3>
|
||||
|
||||
<p>
|
||||
There is an unlimited number of ways the the
|
||||
<tt>iterator_adaptors</tt> class can be used to create iterators. One
|
||||
interesting exercise would be to re-implement the iterators of
|
||||
<tt>std::list</tt> and <tt>std::slist</tt> using
|
||||
<tt>iterator_adaptors</tt>, where the adapted <tt>Iterator</tt> types
|
||||
would be node pointers.
|
||||
|
||||
|
||||
<h3>Notes</h3>
|
||||
|
||||
<p>
|
||||
<a name="1">[1]</a>
|
||||
If your compiler does not support partial specialization and hence
|
||||
does not have a working <tt>std::iterator_traits</tt> class, you will
|
||||
not be able to use the defaults and will need to supply your own
|
||||
<tt>Traits</tt> and <tt>ConstTraits</tt> classes.
|
||||
|
||||
<p>
|
||||
<a name="2">[2]</a>
|
||||
The reference type could also be obtained from
|
||||
<tt>std::iterator_traits</tt>, but that is not portable on compilers
|
||||
that do not support partial specialization.
|
||||
|
||||
<p>
|
||||
<a name="3">[3]</a>
|
||||
It would have been more elegant to implement <tt>indirect_iterators</tt>
|
||||
using <tt>transform_iterators</tt>, but for subtle reasons that would require
|
||||
the use of <tt>boost::remove_cv</tt> which is not portable.
|
||||
|
||||
<h3>Implementation Notes</h3>
|
||||
|
||||
The code is somewhat complicated because there are three iterator
|
||||
adaptor class: <tt>forward_iterator_adaptor</tt>,
|
||||
<tt>bidirectional_iterator_adaptor</tt>, and
|
||||
<tt>random_access_iterator_adaptor</tt>. The alternative would be to
|
||||
just have one iterator adaptor equivalent to the
|
||||
<tt>random_access_iterator_adaptor</tt>. The reason for going with
|
||||
the three adaptors is that according to 14.5.3p5 in the C++ Standard,
|
||||
friend functions defined inside a template class body are instantiated
|
||||
when the template class is instantiated. This means that if we only
|
||||
used the one iterator adaptor, then if the adapted iterator did not
|
||||
meet all of the requirements for a
|
||||
<a href="http://www.sgi.com/Technology/STL/RandomAccessIterator.html">
|
||||
RandomAccessIterator</a> then a compiler error should occur. Many
|
||||
current compilers in fact do not instantiate the friend functions
|
||||
unless used, so we could get away with the one iterator adaptor in
|
||||
most cases. However, out of respect for the standard this implementation
|
||||
uses the three adaptors.

// 03 Apr 08 Added convertible_to_bool (Daniel Frey)
|

// 01 Oct 01 Added tests for "left" operators
|
||||
// and new grouped operators. (Helmut Zeisel)
|
||||
// 20 May 01 Output progress messages. Added tests for new operator
|
||||
// templates. Updated random number generator. Changed tests to
|
||||
// use Boost Test Tools library. (Daryle Walker)
|
||||
// 04 Jun 00 Added regression test for a bug I found (David Abrahams)
|
||||
// 17 Jun 00 Fix for broken compilers (Aleksey Gurtovoy)
|
||||
// ?? ??? 00 Major update to randomly test all one- and two- argument forms by
|
||||
// wrapping integral types and comparing the results of operations
|
||||
// to the results for the raw types (David Abrahams)
|
