  Fixed intel-darwin unresolved symbols by changing the 
  wide integer type from unsigned int (which managles as
  a 'j') to an int (which mangles as an 'i').  This
  change makes intel-darwin generated code match the 
  darwin toolset generated code.
  
  Intel reports this won't be fixed in 10.1 because it's
  an ABI breanking chanage so we won't see this patched 
  until the 10.2 compilers.

    get_allocator wasn't compiling when the allocator workaround is used because it

    use value_alloc_ when it's available (it's only unavailable on compilers with
    C++0x support, which don't require the workaround).

Collection</h1>
<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>
<table border summary="">
<tr>
<th>Name</th>
<th>Expression</th>
<th>Return type</th>
<th>Semantics</th>
</tr>
<tr>
<td valign="top">Front</td>
<td valign="top"><tt>a.front()</tt></td>
<td valign="top"><tt>reference</tt> if <tt>a</tt> is mutable,<br>
<tt>const_reference</tt> otherwise.</td>
<td valign="top">Equivalent to <tt>*(a.begin())</tt>.</td>
</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>
<table border summary="">
<tr>
<th>Name</th>
<th>Expression</th>
<th>Return type</th>
<th>Semantics</th>
</tr>
<tr>
<td valign="top">Beginning of range</td>
<td valign="top"><tt>a.rbegin()</tt></td>
<td valign="top"><tt>reverse_iterator</tt> if <tt>a</tt> is mutable,
<tt>const_reverse_iterator</tt> otherwise.</td>
<td valign="top">Equivalent to
<tt>X::reverse_iterator(a.end())</tt>.</td>
</tr>
<tr>
<td valign="top">End of range</td>
<td valign="top"><tt>a.rend()</tt></td>
<td valign="top"><tt>reverse_iterator</tt> if <tt>a</tt> is mutable,
<tt>const_reverse_iterator</tt> otherwise.</td>
<td valign="top">Equivalent to
<tt>X::reverse_iterator(a.begin())</tt>.</td>
</tr>
<tr>
<td valign="top">Back</td>
<td valign="top"><tt>a.back()</tt></td>
<td valign="top"><tt>reference</tt> if <tt>a</tt> is mutable,<br>
<tt>const_reference</tt> otherwise.</td>
<td valign="top">Equivalent to <tt>*(--a.end())</tt>.</td>
</tr>
</table>
<h4>SequentialCollection</h4>
<p>The elements are arranged in a strict linear order. No extra methods are
required.</p>
<h4>RandomAccessCollection</h4>
<p>The iterators of a RandomAccessCollection satisfy all of the
requirements of <a href=
"http://www.sgi.com/tech/stl/RandomAccessIterator.html">RandomAccessIterator</a>
except that the reference type does not have to be a real C++ reference. In
addition, a RandomAccessCollection provides an element access operator.</p>
<table border summary="">
<tr>
<th>Name</th>
<th>Expression</th>
<th>Return type</th>
<th>Semantics</th>
</tr>
<tr>
<td valign="top">Element Access</td>
<td valign="top"><tt>a[n]</tt></td>
<td valign="top"><tt>reference</tt> if <tt>a</tt> is mutable,
<tt>const_reference</tt> otherwise.</td>
<td valign="top">Returns the nth element of the Collection. <tt>n</tt>
must be convertible to <tt>size_type</tt>. Precondition: <tt>0 &lt;= n
&lt; a.size()</tt>.</td>
</tr>
</table>
<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
reference object must result in an assignment to the object in the
Collection (again, which is trivially true if they are the same object, but
non-trivial if the reference type is a proxy class).</p>

<h2><a name="concept:MultiPassInputIterator" id=
"concept:MultiPassInputIterator"></a> Multi-Pass Input Iterator</h2>
<p>This concept is a refinement of <a href=
"http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>, adding
the 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 Multi-Pass Input Iterator
is very similar to the <a href=
"http://www.sgi.com/tech/stl/ForwardIterator.html">Forward Iterator</a>.
The only difference is that a <a href=
"http://www.sgi.com/tech/stl/ForwardIterator.html">Forward Iterator</a>
requires the <tt>reference</tt> type to be <tt>value_type&amp;</tt>,
whereas MultiPassInputIterator is like <a href=
"http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a> in that
the <tt>reference</tt> type merely has to be convertible to
<tt>value_type</tt>.</p>
<h3>Design Notes</h3>
<p>comments by Valentin Bonnard:</p>
<p>I think that introducing Multi-Pass Input Iterator isn't the right
solution. Do you also want to define Multi-Pass Bidirectionnal Iterator and
Multi-Pass Random Access Iterator ? 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>
<p>The terms Forward, Bidirectionnal and Random Access 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 Multi-Pass Input Iterator is just called a Forward
Iterator.</p>
<p>Other translations are:<br>
std::Forward Iterator -&gt; ForwardIterator &amp; Lvalue Iterator<br>
std::Bidirectionnal Iterator -&gt; Bidirectionnal Iterator &amp; Lvalue
Iterator<br>
std::Random Access Iterator -&gt; Random Access Iterator &amp; Lvalue
Iterator<br></p>
<p>Note that in practice the only operation not allowed on my Forward
Iterator which is allowed on std::Forward Iterator is <tt>&amp;*it</tt>. I
think that <tt>&amp;*</tt> is rarely needed in generic code.</p>
<p>reply by Jeremy Siek:</p>
<p>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 Forward Iterator. The right course of action
is to get Forward Iterator, etc. changed in the C++ standard. Once that is
done we can drop Multi-Pass Input Iterator.<br></p>

<H1>Concept: OptionalPointee</H1>
<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&lt;T&gt;, 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&lt;class OptionalPointee&gt;
inline
bool equal_pointees ( OptionalPointee const&amp; x, OptionalPointee const&amp; y )
{
return (!x) != (!y) ? false : ( !x ? true : (*x) == (*y) ) ;
}
template&lt;class OptionalPointee&gt;
struct equal_pointees_t : std::binary_function&lt;OptionalPointee,OptionalPointee,bool&gt;
{
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&lt;class OptionalPointee&gt;
inline
bool less_pointees ( OptionalPointee const&amp; x, OptionalPointee const&amp; y )
{
return !y ? false : ( !x ? true : (*x) < (*y) ) ;
}
template&lt;class OptionalPointee&gt;
struct less_pointees_t : std::binary_function&lt;OptionalPointee,OptionalPointee,bool&gt;
{
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 &lt;
*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&lt;&gt; 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>

<p>The class template <code>boost::base_from_member</code> provides
a workaround for a class that needs to initialize a base class with a
member. The class template is in <cite><a
href="../../boost/utility/base_from_member.hpp">boost/utility/base_from_member.hpp</a></cite>
which is included in <i><a href="../../boost/utility.hpp">boost/utility.hpp</a></i>.</p>
<p>There is test/example code in <cite><a
href="base_from_member_test.cpp">base_from_member_test.cpp</a></cite>.</p>

</ul></li>
</ul>
<h2><a name="rationale">Rationale</a></h2>
<p>When developing a class, sometimes a base class needs to be
initialized with a member of the current class. As a na&iuml;ve
example:</p>
<blockquote><pre>
#include &lt;streambuf&gt; <i>// for std::streambuf</i>
#include &lt;ostream&gt; <i>// for std::ostream</i>
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( &amp;buf )
{}
//...
};
</pre></blockquote>
<p>This is undefined because C++'s initialization order mandates that
the base class is initialized before the member it uses. <a
href="http://www.moocat.org">R. Samuel Klatchko</a> 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.</p>
<p>A custom base class can be made for this idiom:</p>
<blockquote><pre>
#include &lt;streambuf&gt; <i>// for std::streambuf</i>
#include &lt;ostream&gt; <i>// for std::ostream</i>
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( &amp;sbuffer )
{}
//...
};
</pre></blockquote>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<h2><a name="synopsis">Synopsis</a></h2>
<blockquote><pre>
#ifndef BOOST_BASE_FROM_MEMBER_MAX_ARITY
#define BOOST_BASE_FROM_MEMBER_MAX_ARITY 10
#endif
template &lt; typename MemberType, int UniqueID = 0 &gt;
class boost::base_from_member
{
protected:
MemberType member;
base_from_member();
template&lt; typename T1 &gt;
explicit base_from_member( T1 x1 );
template&lt; typename T1, typename T2 &gt;
base_from_member( T1 x1, T2 x2 );
//...
template&lt; typename T1, typename T2, typename T3, typename T4,
typename T5, typename T6, typename T7, typename T8, typename T9,
typename T10 &gt;
base_from_member( T1 x1, T2 x2, T3 x3, T4 x4, T5 x5, T6 x6, T7 x7,
T8 x8, T9 x9, T10 x10 );
};
</pre></blockquote>
<p>The class template has a first template parameter
<var>MemberType</var> representing the type of the based-member.
It has a last template parameter <var>UniqueID</var>, that is an
<code>int</code>, 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 <var>member</var> that the derived class can use
for later base classes (or itself).</p>
<p>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. 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.</p>
<p>The <var>BOOST_BASE_FROM_MEMBER_MAX_ARITY</var> 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.)</p>
<h2><a name="usage">Usage</a></h2>
<p>With the starting example, the <code>fdoutbuf</code> sub-object needs
to be encapsulated in a base class that is inheirited before
<code>std::ostream</code>.</p>
<blockquote><pre>
#include &lt;boost/utility/base_from_member.hpp&gt;
#include &lt;streambuf&gt; <i>// for std::streambuf</i>
#include &lt;ostream&gt; <i>// for std::ostream</i>
class fdoutbuf
: public std::streambuf
{
public:
explicit fdoutbuf( int fd );
//...
};
class fdostream
: private boost::base_from_member&lt;fdoutbuf&gt;
, public std::ostream
{
// Helper typedef's
typedef boost::base_from_member&lt;fdoutbuf&gt; pbase_type;
typedef std::ostream base_type;
public:
explicit fdostream( int fd )
: pbase_type( fd ), base_type( &amp;member )
{}
//...
};
</pre></blockquote>
<p>The base-from-member idiom is an implementation detail, so it
should not be visible to the clients (or any derived classes) of
<code>fdostream</code>. Due to the initialization order, the
<code>fdoutbuf</code> sub-object will get initialized before the
<code>std::ostream</code> sub-object does, making the former
sub-object safe to use in the latter sub-object's construction. Since the
<code>fdoutbuf</code> sub-object of the final type is the only sub-object
with the name &quot;member,&quot; that name can be used
unqualified within the final class.</p>
<h2><a name="example">Example</a></h2>
<p>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.</p>
<blockquote><pre>
#include &lt;boost/utility/base_from_member.hpp&gt;
#include &lt;cstddef&gt; <i>// for NULL</i>
struct an_int
{
int y;
an_int( float yf );
};
class switcher
{
public:
switcher();
switcher( double, int * );
//...
};
class flow_regulator
{
public:
flow_regulator( switcher &amp;, switcher &amp; );
//...
};
template &lt; unsigned Size &gt;
class fan
{
public:
explicit fan( switcher );
//...
};
class system
: private boost::base_from_member&lt;an_int&gt;
, private boost::base_from_member&lt;switcher&gt;
, private boost::base_from_member&lt;switcher, 1&gt;
, private boost::base_from_member&lt;switcher, 2&gt;
, protected flow_regulator
, public fan&lt;6&gt;
{
// Helper typedef's
typedef boost::base_from_member&lt;an_int&gt; pbase0_type;
typedef boost::base_from_member&lt;switcher&gt; pbase1_type;
typedef boost::base_from_member&lt;switcher, 1&gt; pbase2_type;
typedef boost::base_from_member&lt;switcher, 2&gt; pbase3_type;
typedef flow_regulator base1_type;
typedef fan&lt;6&gt; base2_type;
public:
system( double x );
//...
};
system::system( double x )
: pbase0_type( 0.2 )
, pbase1_type()
, pbase2_type( -16, &amp;this-&gt;pbase0_type::member )
, pbase3_type( x, static_cast&lt;int *&gt;(NULL) )
, base1_type( pbase3_type::member, pbase1_type::member )
, base2_type( pbase2_type::member )
{
//...
}
</pre></blockquote>
<p>The final class has multiple sub-objects with the name
&quot;member,&quot; so any use of that name needs qualification by
a name of the appropriate base type. (Using <code>typedef</code>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 <code>an_int boost::base_from_member&lt;an_int,
0&gt; :: *</code>) instead of a pointer to the member (having a type of
<code>an_int *</code>). The new problem is fixed by qualifying the
sub-object with &quot;<code>this-&gt;</code>,&quot; and is needed just
for pointers, and not for references or values.</p>
<p>There are some argument conversions in the initialization. The
constructor argument for <code>pbase0_type</code> is converted from
<code>double</code> to <code>float</code>. The first constructor
argument for <code>pbase2_type</code> is converted from <code>int</code>
to <code>double</code>. The second constructor argument for
<code>pbase3_type</code> is a special case of necessary conversion; all
forms of the null-pointer literal in C++ 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 <code>switcher</code>'s constructor.</p>

&lt;<a href="../../boost/detail/call_traits.hpp">boost/call_traits.hpp</a>&gt;</h1>
<p>All of the contents of &lt;boost/call_traits.hpp&gt; are
defined inside namespace boost.</p>
<p>The template class call_traits&lt;T&gt; encapsulates the
&quot;best&quot; method to pass a parameter of some type T to or
from a function, and consists of a collection of typedefs defined
as in the table below. The purpose of call_traits is to ensure
that problems like &quot;<a href="#refs">references to references</a>&quot;
never occur, and that parameters are passed in the most efficient
manner possible (see <a href="#examples">examples</a>). In each
case if your existing practice is to use the type defined on the
left, then replace it with the call_traits defined type on the
right. </p>
<p>Note that for compilers that do not support either partial
specialization or member templates, no benefit will occur from
using call_traits: the call_traits defined types will always be
the same as the existing practice in this case. In addition if
only member templates and not partial template specialisation is
support by the compiler (for example Visual C++ 6) then
call_traits can not be used with array types (although it can be
used to solve the reference to reference problem).</p>

<p>Notes:</p>
<ol>
<li>If T is already reference type, then call_traits is
defined such that <a href="#refs">references to
references</a> do not occur (requires partial
specialization).</li>
<li>If T is an array type, then call_traits defines <code>value_type</code>
as a &quot;constant pointer to type&quot; rather than an
&quot;array of type&quot; (requires partial
specialization). Note that if you are using value_type as
a stored value then this will result in storing a &quot;constant
pointer to an array&quot; rather than the array itself.
This may or may not be a good thing depending upon what
you actually need (in other words take care!).</li>
<li>If T is a small built in type or a pointer, then <code>param_type</code>
is defined as <code>T const</code>, instead of <code>T
const&amp;</code>. This can improve the ability of the
compiler to optimize loops in the body of the function if
they depend upon the passed parameter, the semantics of
the passed parameter is otherwise unchanged (requires
partial specialization).</li>
</ol>
<p>&nbsp;</p>
<h3>Copy constructibility</h3>
<p>The following table defines which call_traits types can always
be copy-constructed from which other types, those entries marked
with a '?' are true only if and only if T is copy constructible:</p>

<h4>Example 1:</h4>
<p>The following class is a trivial class that stores some type T
by value (see the <a href="call_traits_test.cpp">call_traits_test.cpp</a>
file), the aim is to illustrate how each of the available
call_traits typedefs may be used:</p>
<pre>template &lt;class T&gt;
struct contained
{
// define our typedefs first, arrays are stored by value
// so value_type is not the same as result_type:
typedef typename boost::call_traits&lt;T&gt;::param_type param_type;
typedef typename boost::call_traits&lt;T&gt;::reference reference;
typedef typename boost::call_traits&lt;T&gt;::const_reference const_reference;
typedef T value_type;
typedef typename boost::call_traits&lt;T&gt;::value_type result_type;
// stored value:
value_type v_;
// constructors:
contained() {}
contained(param_type p) : v_(p){}
// return byval:
result_type value() { return v_; }
// return by_ref:
reference get() { return v_; }
const_reference const_get()const { return v_; }
// pass value:
void call(param_type p){}
};</pre>
<h4><a name="refs"></a>Example 2 (the reference to reference

binder1st(const Operation&amp; x, const typename Operation::first_argument_type&amp; y);
typename Operation::result_type operator()(const typename Operation::second_argument_type&amp; x) const;
}; </pre>
<p>Now consider what happens in the relatively common case that
the functor takes its second argument as a reference, that
implies that <code>Operation::second_argument_type</code> is a
reference type, <code>operator()</code> will now end up taking a
reference to a reference as an argument, and that is not
currently legal. The solution here is to modify <code>operator()</code>
to use call_traits:</p>
<pre>typename Operation::result_type operator()(typename call_traits&lt;typename Operation::second_argument_type&gt;::param_type x) const;</pre>
<p>Now in the case that <code>Operation::second_argument_type</code>
is a reference type, the argument is passed as a reference, and
the no &quot;reference to reference&quot; occurs.</p>
<h4><a name="ex3"></a>Example 3 (the make_pair problem):</h4>
<p>If we pass the name of an array as one (or both) arguments to <code>std::make_pair</code>,
then template argument deduction deduces the passed parameter as
&quot;const reference to array of T&quot;, this also applies to
string literals (which are really array literals). Consequently
instead of returning a pair of pointers, it tries to return a
pair of arrays, and since an array type is not copy-constructible
the code fails to compile. One solution is to explicitly cast the
arguments to make_pair to pointers, but call_traits provides a
better (i.e. automatic) solution (and one that works safely even
in generic code where the cast might do the wrong thing):</p>
<pre>template &lt;class T1, class T2&gt;
std::pair&lt;
typename boost::call_traits&lt;T1&gt;::value_type,
typename boost::call_traits&lt;T2&gt;::value_type&gt;
make_pair(const T1&amp; t1, const T2&amp; t2)
{
return std::pair&lt;
typename boost::call_traits&lt;T1&gt;::value_type,
typename boost::call_traits&lt;T2&gt;::value_type&gt;(t1, t2);
}</pre>
<p>Here, the deduced argument types will be automatically
degraded to pointers if the deduced types are arrays, similar
situations occur in the standard binders and adapters: in
principle in any function that &quot;wraps&quot; a temporary
whose type is deduced. Note that the function arguments to
make_pair are not expressed in terms of call_traits: doing so
would prevent template argument deduction from functioning.</p>
<h4><a name="ex4"></a>Example 4 (optimising fill):</h4>
<p>The call_traits template will &quot;optimize&quot; the passing
of a small built-in type as a function parameter, this mainly has
an effect when the parameter is used within a loop body. In the
following example (see <a
href="../type_traits/examples/fill_example.cpp">fill_example.cpp</a>),
a version of std::fill is optimized in two ways: if the type
passed is a single byte built-in type then std::memset is used to
effect the fill, otherwise a conventional C++ implemention is
used, but with the passed parameter &quot;optimized&quot; using
call_traits:</p>
<pre>namespace detail{
template &lt;bool opt&gt;
struct filler
{
template &lt;typename I, typename T&gt;
static void do_fill(I first, I last, typename boost::call_traits&lt;T&gt;::param_type val)
{
while(first != last)
{
*first = val;
++first;
}
}
};
template &lt;&gt;
struct filler&lt;true&gt;
{
template &lt;typename I, typename T&gt;
static void do_fill(I first, I last, T val)
{
memset(first, val, last-first);
}
};
}
template &lt;class I, class T&gt;
inline void fill(I first, I last, const T&amp; val)
{
enum{ can_opt = boost::is_pointer&lt;I&gt;::value
&amp;&amp; boost::is_arithmetic&lt;T&gt;::value
&amp;&amp; (sizeof(T) == 1) };
typedef detail::filler&lt;can_opt&gt; filler_t;
filler_t::template do_fill&lt;I,T&gt;(first, last, val);
}</pre>
<p>Footnote: the reason that this is &quot;optimal&quot; for
small built-in types is that with the value passed as &quot;T
const&quot; instead of &quot;const T&amp;&quot; the compiler is
able to tell both that the value is constant and that it is free
of aliases. With this information the compiler is able to cache
the passed value in a register, unroll the loop, or use
explicitly parallel instructions: if any of these are supported.
Exactly how much mileage you will get from this depends upon your
compiler - we could really use some accurate benchmarking
software as part of boost for cases like this.</p>
<p>Note that the function arguments to fill are not expressed in
terms of call_traits: doing so would prevent template argument
deduction from functioning. Instead fill acts as a &quot;thin
wrapper&quot; that is there to perform template argument
deduction, the compiler will optimise away the call to fill all
together, replacing it with the call to filler&lt;&gt;::do_fill,
which does use call_traits.</p>
<h3>Rationale</h3>
<p>The following notes are intended to briefly describe the
rational behind choices made in call_traits.</p>
<p>All user-defined types follow &quot;existing practice&quot;
and need no comment.</p>
<p>Small built-in types (what the standard calls fundamental
types [3.9.1]) differ from existing practice only in the <i>param_type</i>
typedef. In this case passing &quot;T const&quot; is compatible
with existing practice, but may improve performance in some cases
(see <a href="#ex4">Example 4</a>), in any case this should never
be any worse than existing practice.</p>
<p>Pointers follow the same rational as small built-in types.</p>
<p>For reference types the rational follows <a href="#refs">Example
2</a> - references to references are not allowed, so the
call_traits members must be defined such that these problems do
not occur. There is a proposal to modify the language such that
&quot;a reference to a reference is a reference&quot; (issue #106,
submitted by Bjarne Stroustrup), call_traits&lt;T&gt;::value_type
and call_traits&lt;T&gt;::param_type both provide the same effect
as that proposal, without the need for a language change (in
other words it's a workaround).</p>
<p>For array types, a function that takes an array as an argument
will degrade the array type to a pointer type: this means that
the type of the actual parameter is different from its declared
type, something that can cause endless problems in template code
that relies on the declared type of a parameter. For example:</p>
<pre>template &lt;class T&gt;
struct A
{
void foo(T t);
};</pre>
<p><font face="Times New Roman">In this case if we instantiate
A&lt;int[2]&gt; then the declared type of the parameter passed to
member function foo is int[2], but it's actual type is const int*,
if we try to use the type T within the function body, then there
is a strong likelyhood that our code will not compile:</font></p>
<pre>template &lt;class T&gt;
void A&lt;T&gt;::foo(T t)
{
T dup(t); // doesn't compile for case that T is an array.
}</pre>
<p>By using call_traits the degradation from array to pointer is
explicit, and the type of the parameter is the same as it's
declared type:</p>
<pre>template &lt;class T&gt;
struct A
{
void foo(typename call_traits&lt;T&gt;::value_type t);
};
template &lt;class T&gt;
void A&lt;T&gt;::foo(typename call_traits&lt;T&gt;::value_type t)
{
typename call_traits&lt;T&gt;::value_type dup(t); // OK even if T is an array type.
}</pre>
<p>For value_type (return by value), again only a pointer may be
returned, not a copy of the whole array, and again call_traits
makes the degradation explicit. The value_type member is useful
whenever an array must be explicitly degraded to a pointer - <a
href="#ex3">Example 3</a> provides the test case (Footnote: the
array specialisation for call_traits is the least well understood
of all the call_traits specialisations, if the given semantics
cause specific problems for you, or don't solve a particular
array-related problem, then I would be interested to hear about
it. Most people though will probably never need to use this
specialisation).</p>

The header <STRONG>&lt;boost/checked_delete.hpp&gt;</STRONG> defines two

and two class templates, <STRONG>checked_deleter</STRONG> and <STRONG>checked_array_deleter</STRONG>.
</p>
<P>The C++ Standard allows, in 5.3.5/5, pointers to incomplete class types to be
deleted with a <EM>delete-expression</EM>. When the class has a non-trivial
destructor, or a class-specific operator delete, the behavior is undefined.
Some compilers issue a warning when an incomplete type is deleted, but
unfortunately, not all do, and programmers sometimes ignore or disable
warnings.</P>
<P>A particularly troublesome case is when a smart pointer's destructor, such as <STRONG>
boost::scoped_ptr&lt;T&gt;::~scoped_ptr</STRONG>, is instantiated with an
incomplete type. This can often lead to silent, hard to track failures.</P>
<P>The supplied function and class templates can be used to prevent these problems,
as they require a complete type, and cause a compilation error otherwise.</P>

<p>All of the contents of &lt;boost/compressed_pair.hpp&gt; are defined inside
namespace boost.</p>
<p>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.</p>
<pre>template &lt;class T1, class T2&gt;
class compressed_pair
{
public:
typedef T1 first_type;
typedef T2 second_type;
typedef typename call_traits&lt;first_type&gt;::param_type first_param_type;
typedef typename call_traits&lt;second_type&gt;::param_type second_param_type;
typedef typename call_traits&lt;first_type&gt;::reference first_reference;
typedef typename call_traits&lt;second_type&gt;::reference second_reference;
typedef typename call_traits&lt;first_type&gt;::const_reference first_const_reference;
typedef typename call_traits&lt;second_type&gt;::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&amp; operator=(const compressed_pair&amp;);
first_reference first();
first_const_reference first() const;
second_reference second();
second_const_reference second() const;
void swap(compressed_pair&amp; 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 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.</P>
<p>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.</p>
<p>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.</p>

<A NAME="introduction"></A>
The <TT>enable_if</TT> family of templates is a set of tools to allow a function template or a class template specialization
to include or exclude itself from a set of matching functions or specializations
based on properties of its template arguments.
For example, one can define function templates that
are only enabled for, and thus only match, an arbitrary set of types
defined by a traits class. The <TT>enable_if</TT> templates can also be
applied to enable class template specializations. Applications of
<TT>enable_if</TT> are discussed in length
in&nbsp;[<A HREF="#jarvi:03:cuj_arbitrary_overloading"><CITE>1</CITE></A>] and&nbsp;[<A HREF="#jarvi:03:c++typeclasses"><CITE>2</CITE></A>].<BR>

<A NAME="sec:background"></A>
Sensible operation of template function overloading in C++ relies
on the <EM>SFINAE</EM> (substitution-failure-is-not-an-error)
principle&nbsp;[<A HREF="#vandevoorde2002:templates"><CITE>3</CITE></A>]: if an invalid argument
or return type is formed during the instantiation of a function
template, the instantiation is removed from the overload resolution
set instead of causing a compilation error. The following example,
taken from&nbsp;[<A HREF="#jarvi:03:cuj_arbitrary_overloading"><CITE>1</CITE></A>],
demonstrates why this is important:
<PRE>int negate(int i) { return -i; }
template &lt;class F&gt;
typename F::result_type negate(const F&amp; f) { return -f(); }
</PRE>
Suppose the compiler encounters the call <TT>negate(1)</TT>. The first
definition is obviously a better match, but the compiler must
nevertheless consider (and instantiate the prototypes) of both
definitions to find this out. Instantiating the latter definition with
<TT>F</TT> as <TT>int</TT> would result in:
<PRE>int::result_type negate(const int&amp;);
</PRE>
where the return type is invalid. If this was an error, adding an unrelated function template
(that was never called) could break otherwise valid code.
Due to the SFINAE principle the above example is not, however, erroneous.
The latter definition of <TT>negate</TT> is simply removed from the overload resolution set.<BR>
<BR>
The <TT>enable_if</TT> templates are tools for controlled creation of the SFINAE
conditions.<BR>
<BR>
<!--TOC section The <TT>enable_if</TT> templates-->
<H2><A NAME="htoc4">2</A>&nbsp;&nbsp;The <TT>enable_if</TT> templates</H2><!--SEC END -->
<A NAME="enable_if"></A>
The names of the <TT>enable_if</TT> templates have three parts: an optional <TT>lazy_</TT> tag,
either <TT>enable_if</TT> or <TT>disable_if</TT>, and an optional <TT>_c</TT> tag.
All eight combinations of these parts are supported.
The meaning of the <TT>lazy_</TT> tag is described in Section&nbsp;<A HREF="#sec:enable_if_lazy">3.3</A>.
The second part of the name indicates whether a true condition argument should
enable or disable the current overload.
The third part of the name indicates whether the condition argument is a <TT>bool</TT> value
(<TT>_c</TT> suffix), or a type containing a static <TT>bool</TT> constant named <TT>value</TT> (no suffix).
The latter version interoperates with Boost.MPL. <BR>
<BR>
The definitions of <TT>enable_if_c</TT> and <TT>enable_if</TT> are as follows (we use <TT>enable_if</TT> templates
unqualified but they are in the <TT>boost</TT> namespace).
<PRE>template &lt;bool B, class T = void&gt;
struct enable_if_c {
typedef T type;
};
template &lt;class T&gt;
struct enable_if_c&lt;false, T&gt; {};
template &lt;class Cond, class T = void&gt;
struct enable_if : public enable_if_c&lt;Cond::value, T&gt; {};
</PRE>
An instantiation of the <TT>enable_if_c</TT> template with the parameter
<TT>B</TT> as <TT>true</TT> contains a member type <TT>type</TT>, defined
to be <TT>T</TT>. If <TT>B</TT> is
<TT>false</TT>, no such member is defined. Thus
<TT>enable_if_c&lt;B, T&gt;::type</TT> is either a valid or an invalid type
expression, depending on the value of <TT>B</TT>.
When valid, <TT>enable_if_c&lt;B, T&gt;::type</TT> equals <TT>T</TT>.
The <TT>enable_if_c</TT> template can thus be used for controlling when functions are considered for
overload resolution and when they are not.
For example, the following function is defined for all arithmetic types (according to the
classification of the <A HREF="../type_traits/index.html">Boost type_traits library</A>):
<PRE>template &lt;class T&gt;
typename enable_if_c&lt;boost::is_arithmetic&lt;T&gt;::value, T&gt;::type
foo(T t) { return t; }
</PRE>
The <TT>disable_if_c</TT> template is provided as well, and has the
same functionality as <TT>enable_if_c</TT> except for the negated condition. The following
function is enabled for all non-arithmetic types.
<PRE>template &lt;class T&gt;
typename disable_if_c&lt;boost::is_arithmetic&lt;T&gt;::value, T&gt;::type
bar(T t) { return t; }
</PRE>
For easier syntax in some cases and interoperation with Boost.MPL we provide versions of
the <TT>enable_if</TT> templates taking any type with a <TT>bool</TT> member constant named
<TT>value</TT> as the condition argument.
The MPL <TT>bool_</TT>, <TT>and_</TT>, <TT>or_</TT>, and <TT>not_</TT> templates are likely to be
useful for creating such types. Also, the traits classes in the Boost.Type_traits library
follow this convention.
For example, the above example function <TT>foo</TT> can be alternatively written as:
<PRE>template &lt;class T&gt;
typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type
foo(T t) { return t; }
</PRE>
<!--TOC section Using <TT>enable_if</TT>-->
<H2><A NAME="htoc5">3</A>&nbsp;&nbsp;Using <TT>enable_if</TT></H2><!--SEC END -->
<A NAME="sec:using_enable_if"></A>
The <TT>enable_if</TT> templates are defined in
<TT>boost/utility/enable_if.hpp</TT>, which is included by <TT>boost/utility.hpp</TT>.<BR>
<BR>
The <TT>enable_if</TT> template can be used either as the return type, or as an
extra argument. For example, the <TT>foo</TT> function in the previous section could also be written
as:
<PRE>template &lt;class T&gt;
T foo(T t, typename enable_if&lt;boost::is_arithmetic&lt;T&gt; &gt;::type* dummy = 0);
</PRE>Hence, an extra parameter of type <TT>void*</TT> is added, but it is given
a default value to keep the parameter hidden from client code.
Note that the second template argument was not given to <TT>enable_if</TT>, as the default
<TT>void</TT> gives the desired behavior.<BR>
<BR>
Whether to write the enabler as an argument or within the return type is
largely a matter of taste, but for certain functions, only one
alternative is possible:
<UL><LI>
Operators have a fixed number of arguments, thus <TT>enable_if</TT> must be used in the return type.
<LI>Constructors and destructors do not have a return type; an extra argument is the only option.
<LI>There does not seem to be a way to specify an enabler for a conversion operator. Converting constructors,
however, can have enablers as extra default arguments.
</UL>
<!--TOC subsection Enabling template class specializations-->
<H3><A NAME="htoc6">3.1</A>&nbsp;&nbsp;Enabling template class specializations</H3><!--SEC END -->
<A NAME="sec:enable_if_classes"></A>
Class template specializations can be enabled or disabled with <TT>enable_if</TT>.
One extra template parameter needs to be added for the enabler expressions.
This parameter has the default value <TT>void</TT>.
For example:
<PRE>template &lt;class T, class Enable = void&gt;
class A { ... };
template &lt;class T&gt;
class A&lt;T, typename enable_if&lt;is_integral&lt;T&gt; &gt;::type&gt; { ... };
template &lt;class T&gt;
class A&lt;T, typename enable_if&lt;is_float&lt;T&gt; &gt;::type&gt; { ... };
</PRE>Instantiating <TT>A</TT> with any integral type matches the first specialization,
whereas any floating point type matches the second one. All other types
match the primary template.
The condition can be any compile-time boolean expression that depends on the
template arguments of the class.
Note that again, the second argument to <TT>enable_if</TT> is not needed; the default (<TT>void</TT>)
is the correct value.<BR>
<BR>
<!--TOC subsection Overlapping enabler conditions-->
<H3><A NAME="htoc7">3.2</A>&nbsp;&nbsp;Overlapping enabler conditions</H3><!--SEC END -->
<A NAME="sec:overlapping_conditions"></A>
Once the compiler has examined the enabling conditions and included the
function into the overload resolution set, normal C++ overload resolution
rules are used to select the best matching function.
In particular, there is no ordering between enabling conditions.
Function templates with enabling conditions that are not mutually exclusive can
lead to ambiguities. For example:
<PRE>template &lt;class T&gt;
typename enable_if&lt;boost::is_integral&lt;T&gt;, void&gt;::type
foo(T t) {}
template &lt;class T&gt;
typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, void&gt;::type
foo(T t) {}
</PRE>
All integral types are also arithmetic. Therefore, say, for the call <TT>foo(1)</TT>,
both conditions are true and both functions are thus in the overload resolution set.
They are both equally good matches and thus ambiguous.
Of course, more than one enabling condition can be simultaneously true as long as
other arguments disambiguate the functions.<BR>
<BR>
The above discussion applies to using <TT>enable_if</TT> in class template
partial specializations as well.<BR>
<BR>
<!--TOC subsection Lazy <TT>enable_if</TT>-->
<H3><A NAME="htoc8">3.3</A>&nbsp;&nbsp;Lazy <TT>enable_if</TT></H3><!--SEC END -->
<A NAME="sec:enable_if_lazy"></A>
In some cases it is necessary to avoid instantiating part of a
function signature unless an enabling condition is true. For example:
<PRE>template &lt;class T, class U&gt; class mult_traits;
template &lt;class T, class U&gt;
typename enable_if&lt;is_multipliable&lt;T, U&gt;, typename mult_traits&lt;T, U&gt;::type&gt;::type
operator*(const T&amp; t, const U&amp; u) { ... }
</PRE>Assume the class template <TT>mult_traits</TT> is a traits class defining
the resulting type of a multiplication operator. The <TT>is_multipliable</TT> traits
class specifies for which types to enable the operator. Whenever
<TT>is_multipliable&lt;A, B&gt;::value</TT> is <TT>true</TT> for some types <TT>A</TT> and <TT>B</TT>,
then <TT>mult_traits&lt;A, B&gt;::type</TT> is defined.<BR>
<BR>
Now, trying to invoke (some other overload) of <TT>operator*</TT> with, say, operand types <TT>C</TT> and <TT>D</TT>
for which <TT>is_multipliable&lt;C, D&gt;::value</TT> is <TT>false</TT>
and <TT>mult_traits&lt;C, D&gt;::type</TT> is not defined is an error on some compilers.
The SFINAE principle is not applied because
the invalid type occurs as an argument to another template. The <TT>lazy_enable_if</TT>
and <TT>lazy_disable_if</TT> templates (and their <TT>_c</TT> versions) can be used in such
situations:
<PRE>template&lt;class T, class U&gt;
typename lazy_enable_if&lt;is_multipliable&lt;T, U&gt;, mult_traits&lt;T, U&gt; &gt;::type
operator*(const T&amp; t, const U&amp; u) { ... }
</PRE>The second argument of <TT>lazy_enable_if</TT> must be a class type
that defines a nested type named <TT>type</TT> whenever the first
parameter (the condition) is true.<BR>
<BR>
<!--TOC paragraph Note-->
<H5>Note</H5><!--SEC END -->
Referring to one member type or static constant in a traits class
causes all of the members (type and static constant) of that
specialization to be instantiated. Therefore, if your traits classes
can sometimes contain invalid types, you should use two distinct
templates for describing the conditions and the type mappings. In the
above example, <TT>is_multipliable&lt;T, U&gt;::value</TT> defines when
<TT>mult_traits&lt;T, U&gt;::type</TT> is valid.<BR>
<BR>
<!--TOC subsection Compiler workarounds-->
<H3><A NAME="htoc9">3.4</A>&nbsp;&nbsp;Compiler workarounds</H3><!--SEC END -->
<A NAME="sec:workarounds"></A>
Some compilers flag functions as ambiguous if the only distinguishing factor is a different
condition in an enabler (even though the functions could never be ambiguous). For example,
some compilers (e.g. GCC 3.2) diagnose the following two functions as ambiguous:
<PRE>template &lt;class T&gt;
typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type
foo(T t);
template &lt;class T&gt;
typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type
foo(T t);
</PRE>Two workarounds can be applied:
<UL><LI>
Use an extra dummy parameter which disambiguates the functions. Use a default value for
it to hide the parameter from the caller. For example:
<PRE>template &lt;int&gt; struct dummy { dummy(int) {} };
template &lt;class T&gt;
typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type
foo(T t, dummy&lt;0&gt; = 0);
template &lt;class T&gt;
typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type
foo(T t, dummy&lt;1&gt; = 0);
</PRE><BR>
<BR>
<LI>Define the functions in different namespaces and bring them into a common
namespace with <TT>using</TT> declarations:
<PRE>namespace A {
template &lt;class T&gt;
typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type
foo(T t);
}
namespace B {
template &lt;class T&gt;
typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type
foo(T t);
}
using A::foo;
using B::foo;
</PRE>
Note that the second workaround above cannot be used for member
templates. On the other hand, operators do not accept extra arguments,
which makes the first workaround unusable. As the net effect,
neither of the workarounds are of assistance for templated operators that
need to be defined as member functions (assignment and
subscript operators).

<h1>Generator Iterator Adaptor</h1>
<p>Defined in header <a href=
"../../boost/generator_iterator.hpp">boost/generator_iterator.hpp</a></p>
<p>The generator iterator adaptor makes it easier to create custom input
iterators from 0-ary functions and function objects. The adaptor takes a
<a href="http://www.sgi.com/tech/stl/Generator.html">Generator</a> and
creates a model of <a href=
"http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>. Each
increment retrieves an item from the generator and makes it available to be
retrieved by dereferencing. The motivation for this iterator is that some
concepts can be more naturally expressed as a generator, while most STL
algorithms expect an iterator. An example is the <a href=
"../random/index.html">Random Number</a> library.</p>
<h2>Synopsis</h2>
<blockquote>
<pre>
namespace boost {
template &lt;class Generator&gt;
class generator_iterator_policies;
template &lt;class Generator&gt;
class generator_iterator_generator;
template &lt;class Generator&gt;
typename generator_iterator_generator&lt;Generator&gt;::type
make_generator_iterator(Generator &amp; gen);
}
</pre>
</blockquote>
<hr>
<h2>The Generator Iterator Generator Class</h2>
<p>The class generator_iterator_generator is a helper class whose purpose
is to construct a generator iterator type. The template parameter for this
class is the Generator function object type that is being wrapped. The
generator iterator adaptor only holds a reference (or pointer) to the
function object, therefore the function object must outlive the generator
iterator adaptor constructed from it.</p>
<pre>
template &lt;class Generator&gt;
class generator_iterator_generator
{
public:
typedef <i>unspecified</i> type; // the resulting generator iterator type
}
</pre>
<h3>Template Parameters</h3>
<table border summary="">
<tr>
<th>Parameter</th>
<th>Description</th>
</tr>
<tr>
<td><tt><a href=
"http://www.sgi.com/tech/stl/Generator.html">Generator</a></tt></td>
<td>The generator (0-ary function object) type being wrapped. The
return type of the function must be defined as
<tt>Generator::result_type</tt>. The function object must be a model of

</tr>
</table>
<h3>Concept Model</h3>
<p>The generator iterator class is a model of <a href=
"http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>.</p>
<h3>Members</h3>
<p>The generator iterator implements the member functions and operators
required of the <a href=

concept.<br></p>
<hr>
<h2><a name="make_generator_iterator" id="make_generator_iterator">The
Generator Iterator Object Generator</a></h2>
<p>The <tt>make_generator_iterator()</tt> function provides a convenient
way to create generator iterator objects. The function saves the user the
trouble of explicitly writing out the iterator types.</p>
<blockquote>
<pre>
template &lt;class Generator&gt;
typename generator_iterator_generator&lt;Generator&gt;::type
make_generator_iterator(Generator &amp; gen);
</pre>

<h3>Example</h3>
<p>The following program shows how <code>generator_iterator</code>
transforms a generator into an input iterator.</p>
<blockquote>
<pre>
#include &lt;iostream&gt;
#include &lt;boost/generator_iterator.hpp&gt;
class my_generator
{
public:
typedef int result_type;
my_generator() : state(0) { }
int operator()() { return ++state; }
private:
int state;
};
int main()
{
my_generator gen;
boost::generator_iterator_generator&lt;my_generator&gt;::type it = boost::make_generator_iterator(gen);
for(int i = 0; i &lt; 10; ++i, ++it)
std::cout &lt;&lt; *it &lt;&lt; std::endl;
}

<H2><A NAME="mot"></A>Motivation</H2>
<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 ftom 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&lt;class InPlaceFactory&gt;
C ( InPlaceFactory const& aFactoty )
:
contained_ ( uninitialized_storage() )
{
aFactory.template apply&lt;X&gt;(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") ) ;
}
</pre>
<HR>
<H2><A NAME="specification">Specification</A></H2>
<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 {} ;
template&lt;class A0&gt;
class in_place_factory : public in_place_factory_base
{
public:</PRE>
<PRE> in_place_factory ( A0 const& a0 ) : m_a0(a0) {}
template&lt; class T &gt;
void apply ( void* address ) const
{
new (address) T(m_a0);
}
private:</PRE>
<PRE> A0 const& m_a0 ;
} ;
template&lt;class A0&gt;
in_place_factory&lt;A0&gt; in_place ( A0 const& a0 )
{
return in_place_factory&lt;A0&gt;(a0);
}
</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&lt;class T, class A0&gt;
class typed_in_place_factory : public typed_in_place_factory_base
{
public:</PRE>
<PRE> typed_in_place_factory ( A0 const& a0 ) : m_a0(a0) {}
void apply ( void* address ) const
{
new (address) T(m_a0);
}
private:</PRE>
<PRE> A0 const& m_a0 ;
} ;
template&lt;class T, class A0&gt;
typed_in_place_factory&lt;A0&gt; in_place ( A0 const& a0 )
{
return typed_in_place_factory&lt;T,A0&gt;(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>
<HR>
<h2><A NAME="container-usage">Container-side Usage</a></h2>
<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&lt;class Expr&gt
C ( Expr const& expr )
:
contained_ ( uninitialized_storage() )
{
construct(expr,&expr)
}
~C() { delete contained_ ; }
template&lt;class InPlaceFactory&gt;
void construct ( InPlaceFactory const& aFactory, boost::in_place_factory_base* )
{
aFactory.template apply&lt;X&gt;(contained_);
}
template&lt;class TypedInPlaceFactory&gt;
void construct ( TypedInPlaceFactory const& aFactory, boost::typed_in_place_factory_base* )
{
aFactory.apply(contained_);
}
X* uninitialized_storage() { return static_cast&lt;X*&gt;(new char[sizeof(X)]) ; }
X* contained_ ;
} ;
</pre>
<hr>
<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&lt;T&gt;(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&lt;X&gt;(456,"world") ) ; // typed_in_place_factory passed
}

Binary Literal Utility
______________________
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.

<h1>Shared Container Iterator</h1>
Defined in header
<a href="../../boost/shared_container_iterator.hpp">boost/shared_container_iterator.hpp</a>
<p>
The purpose of the shared container iterator is to attach the lifetime
of a container to the lifetime of its iterators. In other words, the
container will not be deleted until after all its iterators are
destroyed. The shared container iterator is typically used to
implement functions that return iterators over a range of objects that
only need to exist for the lifetime of the iterators. By returning a
pair of shared iterators from a function, the callee can return a
heap-allocated range of objects whose lifetime is automatically managed.
<p>
The shared container iterator augments an iterator over a shared
container. It maintains a reference count on the shared
container. If only shared container iterators hold references to
the container, the container's lifetime will end when the last shared
container iterator over it is destroyed. In any case, the shared
container is guaranteed to persist beyond the lifetime of all
the iterators. In all other ways, the
shared container iterator behaves the same as its base iterator.
<h2>Synopsis</h2>
<pre>
namespace boost {
template &lt;typename <a href="http://www.sgi.com/tech/stl/Container.html">Container</a>&gt;

<h2><a name="generator">The Shared Container Iterator Type</a></h2>
<pre>
template &lt;typename Container&gt; class shared_container_iterator;
</pre>
The class template <tt>shared_container_iterator</tt>
is the shared container iterator type. The <tt>Container</tt> template
type argument must model the
<a href="http://www.sgi.com/tech/stl/Container.html">Container</a>
concept.
<h3>Example</h3>
<p>
The following example illustrates how to create an iterator that
regulates the lifetime of a reference counted <tt>std::vector</tt>.
Though the original shared pointer <tt>ints</tt> ceases to exist
after <tt>set_range()</tt> returns, the
<tt>shared_counter_iterator</tt> objects maintain references to the
underlying vector and thereby extend the container's lifetime.

<h3>Model of</h3>
The <tt>shared_container_iterator<Container></tt> type models the
same iterator concept as the base iterator
(<tt>Container::iterator</tt>).
<h3>Members</h3>
The shared container iterator type implements the member functions and
operators required of the <a
href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access Iterator</a>
concept, though only operations defined for the base iterator will be valid.
In addition it has the following constructor:
<pre>
shared_container_iterator(Container::iterator const&amp; it,
boost::shared_ptr&lt;Container&gt; const&amp; container)
</pre>
<p>
<hr>
<p>
<h2><a name="make_iterator">The Shared Container Iterator Object Generator</a></h2>
<pre>
template &lt;typename Container&gt;
shared_container_iterator&lt;Container&gt;
make_shared_container_iterator(Container::iterator base,
boost::shared_ptr&lt;Container&gt; const&amp; container)
</pre>
This function provides an alternative to directly constructing a
shared container iterator. Using the object generator, a shared
container iterator can be created and passed to a function without
explicitly specifying its type.
<h3>Example</h3>
This example, similar to the previous, uses
<tt>make_shared_container_iterator()</tt> to create the iterators.
<p>

std::copy(begin,end,std::ostream_iterator&lt;val&gt;(std::cout,<font color="#0000FF">","</font>));
std::cout.put(<font color="#0000FF">'\n'</font>);
}
<B>int</B> main() {
<B>typedef</B> boost::shared_ptr&lt; std::vector&lt;<B>int</B>&gt; &gt; ints_t;
{
ints_t ints(<B>new</B> std::vector&lt;<B>int</B>&gt;());
ints-&gt;push_back(<font color="#0000A0">0</font>);
ints-&gt;push_back(<font color="#0000A0">1</font>);
ints-&gt;push_back(<font color="#0000A0">2</font>);
ints-&gt;push_back(<font color="#0000A0">3</font>);
ints-&gt;push_back(<font color="#0000A0">4</font>);
ints-&gt;push_back(<font color="#0000A0">5</font>);
print_range_nl(boost::make_shared_container_iterator(ints-&gt;begin(),ints),
boost::make_shared_container_iterator(ints-&gt;end(),ints));
}
<B>return</B> <font color="#0000A0">0</font>;
}
</PRE>
Observe that the <tt>shared_container_iterator</tt> type is never
explicitly named. The output from this example is the same as the previous.
<h2><a name="make_range">The Shared Container Iterator Range Generator</a></h2>
<pre>
template &lt;typename Container&gt;
std::pair&lt
shared_container_iterator&lt;Container&gt;,
shared_container_iterator&lt;Container&gt;
&gt;
make_shared_container_range(boost::shared_ptr&lt;Container&gt; const&amp; container);
</pre>
Class <tt>shared_container_iterator</tt> is meant primarily to return,
using iterators, a range of values that we can guarantee will be alive as
long as the iterators are. This is a convenience
function to do just that. It is equivalent to
<pre>
std::make_pair(make_shared_container_iterator(container-&gt;begin(),container),
make_shared_container_iterator(container-&gt;end(),container));
</pre>
<h3>Example</h3>
In the following example, a range of values is returned as a pair of
<tt>shared_container_iterator</tt> objects.
<p>
<a href="./shared_iterator_example3.cpp">shared_iterator_example3.cpp</a>:
<PRE>
<font color="#008040">#include "shared_container_iterator.hpp"</font>

<font color="#008040">#include &lt;algorithm&gt; // for std::copy</font>
<font color="#008040">#include &lt;iostream&gt; </font>
<font color="#008040">#include &lt;vector&gt;</font>
<B>typedef</B> boost::shared_container_iterator&lt; std::vector&lt;<B>int</B>&gt; &gt; iterator;
std::pair&lt;iterator,iterator&gt;
return_range() {
boost::shared_ptr&lt; std::vector&lt;<B>int</B>&gt; &gt; range(<B>new</B> std::vector&lt;<B>int</B>&gt;());
range-&gt;push_back(<font color="#0000A0">0</font>);
range-&gt;push_back(<font color="#0000A0">1</font>);
range-&gt;push_back(<font color="#0000A0">2</font>);
range-&gt;push_back(<font color="#0000A0">3</font>);
range-&gt;push_back(<font color="#0000A0">4</font>);
range-&gt;push_back(<font color="#0000A0">5</font>);
<B>return</B> boost::make_shared_container_range(range);
}
<B>int</B> main() {
iterator i,end;
boost::tie(i,end) = return_range();
std::copy(i,end,std::ostream_iterator&lt;<B>int</B>&gt;(std::cout,<font color="#0000FF">","</font>));
std::cout.put(<font color="#0000FF">'\n'</font>);
<B>return</B> <font color="#0000A0">0</font>;
}
</PRE>
Though the <tt>range</tt> object only lives for the duration of the
<tt>return_range</tt> call, the reference counted
<tt>std::vector</tt> will live until <tt>i</tt> and <tt>end</tt>
are both destroyed. The output from this example is the same as
the previous two.

// next() and prior() are replacements for operator+ and operator- for
// non-random-access iterators. The semantics of these operators are
// such that after executing j = i + n, std::distance(i, j) equals
// n. Tests are provided to ensure next() has the same
// result. Parallel tests are provided for prior(). The tests call
// next() and prior() several times. next() and prior() are very
// simple functions, though, and it would be very strange if these
// tests were to fail.

<h2>
<a name="functions_next_prior">Function</a> templates next() and prior()</h2>
<p>Certain data types, such as the C++ Standard Library's forward and bidirectional
iterators, do not provide addition and subtraction via operator+() or
operator-().&nbsp; This means that non-modifying computation of the next or
prior value requires a temporary, even though operator++() or operator--() is
provided.&nbsp; It also means that writing code like <code>itr+1</code> inside
a template restricts the iterator category to random access iterators.</p>
<p>The next() and prior() functions provide a simple way around these problems:</p>
<blockquote>
<pre>template &lt;class T&gt;
T next(T x) { return ++x; }
template &lt;class T, class Distance&gt;
T next(T x, Distance n)
{
std::advance(x, n);
return x;
}
template &lt;class T&gt;
T prior(T x) { return --x; }
template &lt;class T, class Distance&gt;
T prior(T x, Distance n)
{
std::advance(x, -n);
return x;
}</pre>
</blockquote>
<p>Usage is simple:</p>
<blockquote>
<pre>const std::list&lt;T&gt;::iterator p = get_some_iterator();
const std::list&lt;T&gt;::iterator prev = boost::prior(p);
const std::list&lt;T&gt;::iterator next = boost::next(prev, 2);</pre>
</blockquote>
<p>The distance from the given iterator should be supplied as an absolute value. For
example, the iterator four iterators prior to the given iterator <code>p</code>
may be obtained by <code>prior(p, 4)</code>.</p>

<h2><a name="Class_noncopyable">Class noncopyable</a></h2>
<p>Class <strong>noncopyable</strong> is a base class.&nbsp; Derive your own class
from <strong>noncopyable</strong> when you want to prohibit copy construction
and copy assignment.</p>
<p>Some objects, particularly those which hold complex resources like files or
network connections, have no sensible copy semantics.&nbsp; Sometimes there are
possible copy semantics, but these would be of very limited usefulness and be
very difficult to implement correctly.&nbsp; Sometimes you're implementing a
class that doesn't need to be copied just yet and you don't want to take the
time to write the appropriate functions.&nbsp; Deriving from <b>noncopyable</b>
will prevent the otherwise implicitly-generated functions (which don't have the
proper semantics) from becoming a trap for other programmers.</p>
<p>The traditional way to deal with these is to declare a private copy constructor
and copy assignment, and then document why this is done.&nbsp; But deriving
from <b>noncopyable</b> is simpler and clearer, and doesn't require additional
documentation.</p>
<p>The program <a href="noncopyable_test.cpp">noncopyable_test.cpp</a> can be used
to verify class <b>noncopyable</b> works as expected. It has have been run
successfully under GCC 2.95, Metrowerks CodeWarrior 5.0, and Microsoft Visual
C++ 6.0 sp 3.</p>

<h3>Example</h3>
<blockquote>
<pre>// inside one of your own headers ...
#include &lt;boost/utility.hpp&gt;
class ResourceLadenFileSystem : boost::noncopyable {
...</pre>
</blockquote>
<h3>Rationale</h3>
<p>Class noncopyable has protected constructor and destructor members to emphasize
that it is to be used only as a base class.&nbsp; Dave Abrahams notes concern
about the effect on compiler optimization of adding (even trivial inline)
destructor declarations. He says &quot;Probably this concern is misplaced,
because noncopyable will be used mostly for classes which own resources and
thus have non-trivial destruction semantics.&quot;</p>
<h2><a name="addressof">Function template addressof()</a></h2>
<p>Function <strong>addressof()</strong> returns the address of an object.</p>
<blockquote>
<pre>template &lt;typename T&gt; inline T* addressof(T& v);
template &lt;typename T&gt; inline const T* addressof(const T& v);
template &lt;typename T&gt; inline volatile T* addressof(volatile T& v);
template &lt;typename T&gt; inline const volatile T* addressof(const volatile T& v);
</pre>
</blockquote>
<p>C++ allows programmers to replace the unary <strong>operator&()</strong> class
member used to get the address of an object. Getting the real address of an
object requires ugly casting tricks to avoid invoking the overloaded <strong>operator&()</strong>.
Function <strong>addressof()</strong> provides a wrapper around the necessary
code to make it easy to get an object's real address.
</p>
<p>The program <a href="addressof_test.cpp">addressof_test.cpp</a> can be used to
verify that <b>addressof()</b> works as expected.</p>
<p>Contributed by Brad King based on ideas from discussion with Doug Gregor.</p>

<blockquote>
<pre>#include &lt;boost/utility.hpp&gt;
struct useless_type {};
class nonaddressable {
useless_type operator&() const;

nonaddressable x;
nonaddressable* xp = boost::addressof(x);
// nonaddressable* xpe = &amp;x; /* error */

<h2><a name="result_of">Class template

the type <code>F</code> to be a function pointer,

a binary number arranged as an arbitrary amount of 1s and 0s in

the same rules as those of hex and octal

expands directly to an octal literal during preprocessing, so
there is no overhead at runtime and the result is useable in
any place that an octal literal would be.</p>
<p>In order to directly support binary literals with suffixes,
additional macros of the form BOOST_BINARY_XXX are also
provided, where XXX is a standard integer suffix in all capital

<h2><a name="rationale"></a>Rationale</h2>
<p>Constructing and initializing objects in a generic way is difficult in
C++. The problem is that there are several different rules that apply
for initialization. Depending on the type, the value of a newly constructed
object can be zero-initialized (logically 0), default-constructed (using
the default constructor), or indeterminate. When writing generic code,
this problem must be addressed. The template <code>value_initialized</code> provides
a solution with consistent syntax for value initialization of scalar,
union and class types.
Moreover, <code>value_initialized</code> offers a workaround to various
compiler issues regarding value-initialization.
Furthermore, a <code>const</code> object, <code>initialized_value</code> is provided,
to avoid repeating the type name when retrieving the value from a
<code>value_initialized&lt;T&gt;</code> object.
<br>
</p>
<h2><a name="intro"></a>Introduction</h2>
<p>
There are various ways to initialize a variable, in C++. The following
declarations all <em>may</em> have a local variable initialized to its default
value:
<pre>
T1 var1;
T2 var2 = 0;
T3 var3 = {};
T4 var4 = T4();
</pre>
Unfortunately, whether or not any of those declarations correctly
initialize the variable very much depends on its type. The first
declaration is valid for any <a href="http://www.sgi.com/tech/stl/DefaultConstructible.html">
DefaultConstructible</a> type (by definition).
However, it does not always do an initialization!
It correctly initializes the variable when it's an instance of a
class, and the author of the class has provided a proper default
constructor. On the other hand, the value of <code>var1</code> is <em>indeterminate</em> when
its type is an arithmetic type, like <code>int</code>, <code>float</code>, or <code>char</code>.
An arithmetic variable
is of course initialized properly by the second declaration, <code>T2
var2 = 0</code>. But this initialization form usually won't work for a
class type (unless the class was especially written to support being
initialized that way). The third form, <code>T3 var3 = {}</code>
initializes an aggregate, typically a "C-style" <code>struct</code> or a "C-style" array.
However, the syntax is not allowed for a class that has an explicitly declared
constructor. (But watch out for an upcoming C++ language change,
by Bjarne Stroustrup et al [<a href="#references">1</a>]!)
The fourth form is the most generic form of them, as it
can be used to initialize arithmetic types, class types, aggregates, pointers, and
other types. The declaration, <code>T4 var4 = T4()</code>, should be read
as follows: First a temporary object is created, by <code>T4()</code>.
This object is <a href="#valueinit">value-initialized</a>. Next the temporary
object is copied to the named variable, <code>var4</code>. Afterwards, the temporary
is destroyed. While the copying and the destruction are likely to
be optimized away, C++ still requires the type <code>T4</code> to be
<a href="CopyConstructible.html">CopyConstructible</a>.
(So <code>T4</code> needs to be <em>both</em> DefaultConstructible <em>and</em> CopyConstructible.)
A class may not be CopyConstructible, for example because it may have a
private and undefined copy constructor,
or because it may be derived from <a href="utility.htm#Class_noncopyable">boost::noncopyable</a>.
Scott Meyers [<a href="#references">2</a>] explains why a class would be defined like that.
</p>
<p>
There is another, less obvious disadvantage to the fourth form, <code>T4 var4 = T4()</code>:
It suffers from various <a href="#compiler_issues">compiler issues</a>, causing
a variable to be left uninitialized in some compiler specific cases.
</p>
<p>
The template <a href="#val_init"><code>value_initialized</code></a>
offers a generic way to initialize
an object, like <code>T4 var4 = T4()</code>, but without requiring its type
to be CopyConstructible. And it offers a workaround to those compiler issues
regarding value-initialization as well! It allows getting an initialized
variable of any type; it <em>only</em> requires the type to be DefaultConstructible.
A properly <em>value-initialized</em> object of type <code>T</code> is
constructed by the following declaration:
<pre>
value_initialized&lt;T&gt; var;
</pre>
</p>
<p>
The <code>const</code> object <a href="#initialized_value"><code>initialized_value</code></a>
allows value-initializing a variable as follows:
<pre>
T var = initialized_value ;
</pre>
This form of initialization is semantically equivalent to <code>T4 var4 = T4()</code>,
but robust against the aforementioned compiler issues.
</p>
<h2><a name="details"></a>Details</h2>
<p>The C++ standard [<a href="#references">3</a>] contains the definitions
of <code>zero-initialization</code> and <code>default-initialization</code>.
Informally, zero-initialization means that the object is given the initial
value 0 (converted to the type) and default-initialization means that
POD [<a href="#references">4</a>] types are zero-initialized, while non-POD class
types are initialized with their corresponding default constructors. A
<i>declaration</i> can contain an <i>initializer</i>, which specifies the
object's initial value. The initializer can be just '()', which states that
the object shall be value-initialized (but see below). However, if a <i>declaration</i>
has no <i>initializer</i> and it is of a non-<code>const</code>, non-<code>static</code>
POD type, the initial value is indeterminate: <cite>(see &sect;8.5, [dcl.init], for the
accurate definitions).</cite></p>
<pre>int x ; // no initializer. x value is indeterminate.<br>std::string s ; // no initializer, s is default-constructed.<br><br>int y = int() ; <br>// y is initialized using copy-initialization<br>// but the temporary uses an empty set of parentheses as the initializer,<br>// so it is default-constructed.<br>// A default constructed POD type is zero-initialized,<br>// therefore, y == 0.<br><br>void foo ( std::string ) ;<br>foo ( std::string() ) ; <br>// the temporary string is default constructed <br>// as indicated by the initializer () </pre>
<h3><a name="valueinit">value-initialization</a></h3>
<p>The first <a
href="http://anubis.dkuug.dk/JTC1/SC22/WG21/docs/cwg_defects.html">Technical
Corrigendum for the C++ Standard</a> (TC1), whose draft was released to
the public in November 2001, introduced <a
href="http://anubis.dkuug.dk/JTC1/SC22/WG21/docs/cwg_defects.html#178">Core
Issue 178</a> (among many other issues, of course).</p>
<p> That issue introduced the new concept of <code>value-initialization</code>
(it also fixed the wording for zero-initialization). Informally, value-initialization
is similar to default-initialization with the exception that in some cases
non-static data members and base class sub-objects are also value-initialized.
The difference is that an object that is value-initialized won't have
(or at least is less likely to have) indeterminate values for data members
and base class sub-objects; unlike the case of an object default constructed.
(see Core Issue 178 for a normative description).</p>
<p>In order to specify value-initialization of an object we need to use the
empty-set initializer: (). </p>
<p>As before, a declaration with no intializer specifies default-initialization,
and a declaration with a non-empty initializer specifies copy (=xxx) or
direct (xxx) initialization. </p>
<pre>template&lt;class T&gt; void eat(T);<br>int x ; // indeterminate initial value.<br>std::string s; // default-initialized.<br>eat ( int() ) ; // value-initialized<br>eat ( std::string() ) ; // value-initialized</pre>
<h4><a name="valueinitsyn">value-initialization</a> syntax</h4>
<p>Value initialization is specified using (). However, the empty set of
parentheses is not permitted by the syntax of initializers because it is
parsed as the declaration of a function taking no arguments: </p>
<pre>int x() ; // declares function int(*)()</pre>
<p>Thus, the empty () must be put in some other initialization context.</p>
<p>One alternative is to use copy-initialization syntax:</p>
<pre>int x = int() ;</pre>
<p>This works perfectly fine for POD types. But for non-POD class types,
copy-initialization searches for a suitable constructor, which could be,
for instance, the copy-constructor (it also searches for a suitable conversion
sequence but this doesn't apply in this context). For an arbitrary unknown
type, using this syntax may not have the value-initialization effect intended
because we don't know if a copy from a default constructed object is exactly
the same as a default constructed object, and the compiler is allowed (in
some cases), but never required to, optimize the copy away.</p>
<p>One possible generic solution is to use value-initialization of a non static
data member:</p>
<pre>template&lt;class T&gt; <br>struct W <br>{<br> // value-initialization of 'data' here.<br> W() : data() {}<br> T data ;<br>} ;<br>W&lt;int&gt; w ;<br>// w.data is value-initialized for any type. </pre>
<p>This is the solution as it was supplied by earlier versions of the
<code>value_initialized&lt;T&gt;</code> template
class. Unfortunately this approach suffered from various compiler issues.</p>
<h4><a name="compiler_issues">compiler issues</a> </h4>
Various compilers haven't yet fully implemented value-initialization.
So when an object should be <em>value-initialized</em> (according to the C++ Standard),
it <em>may</em> in practice still be left uninitialized, because of those
compiler issues! It's hard to make a general statement on what those issues
are like, because they depend on the compiler you are using, its version number,
and the type of object you would like to have value-initialized.
Compilers usually support value-initialization for built-in types properly.
But objects of user-defined types that involve <em>aggregates</em> may <em>in some cases</em>
be partially, or even entirely left uninitialized, when they should be value-initialized.
</p>

New versions of <code>value_initialized</code>
(Boost release version 1.35 or higher)
offer a workaround to these issues: <code>value_initialized</code> will now clear
its internal data, prior to constructing the object that it contains.
</p>
<h2><a name="types"></a>Types and objects</h2>
<h2><a name="val_init"><code>template class value_initialized&lt;T&gt;</code></a></h2>
<pre>namespace boost {<br><br>template&lt;class T&gt;<br>class value_initialized<br>{<br> public :<br> value_initialized() : x() {}<br> operator T&amp;() const { return x ; }<br> T&amp; data() const { return x ; }<br> void swap( value_initialized&lt;T&gt;&amp; );<br><br> private :<br> <i>unspecified</i> x ;<br>} ;<br><br>template&lt;class T&gt;<br>T const&amp; get ( value_initialized&lt;T&gt; const&amp; x )<br>{<br> return x.data() ;<br>}<br><br>template&lt;class T&gt;<br>T&amp; get ( value_initialized&lt;T&gt;&amp; x )<br>{<br> return x.data() ;<br>}<br><br>} // namespace boost<br></pre>
<p>An object of this template class is a <code>T</code>-wrapper convertible
to <code>'T&amp;'</code> whose wrapped object (data member of type <code>T</code>)
is <a href="#valueinit">value-initialized</a> upon default-initialization
of this wrapper class: </p>
<pre>int zero = 0 ;<br>value_initialized&lt;int&gt; x ;<br>assert ( x == zero ) ;<br><br>std::string def ;<br>value_initialized&lt; std::string &gt; y ;<br>assert ( y == def ) ;<br></pre>
<p>The purpose of this wrapper is to provide a consistent syntax for value
initialization of scalar, union and class types (POD and non-POD) since
the correct syntax for value initialization varies (see <a
href="#valueinitsyn">value-initialization syntax</a>)</p>
<p>The wrapped object can be accessed either through the conversion operator
<code>T&amp;</code>, the member function <code>data()</code>, or the
non-member function <code>get()</code>: </p>
<pre>void watch(int);<br>value_initialized&lt;int&gt; x;<br><br>watch(x) ; // operator T&amp; used.<br>watch(x.data());<br>watch( get(x) ) // function get() used</pre>
<p>Both <code>const</code> and non-<code>const</code> objects can be wrapped.
Mutable objects can be modified directly from within the wrapper but constant
objects cannot:</p>
<p>When <code>T</code> is a <em>Swappable</em> type, <code>value_initialized&lt;T&gt;</code>
is swappable as well, by calling its <code>swap</code> member function
as well as by calling <code>boost::swap</code>.</p>
<pre>value_initialized&lt;int&gt; x ; <br>static_cast&lt;int&amp;&gt;(x) = 1 ; // OK<br>get(x) = 1 ; // OK<br><br>value_initialized&lt;int const&gt; y ; <br>static_cast&lt;int&amp;&gt;(y) = 1 ; // ERROR: cannot cast to int&amp;<br>static_cast&lt;int const&amp;&gt;(y) = 1 ; // ERROR: cannot modify a const value<br>get(y) = 1 ; // ERROR: cannot modify a const value</pre>
<h3>Warning:</h3>
<p>Both the conversion operator and the <code>data()</code> member function
are <code>const</code> in order to allow access to the wrapped object
from a constant wrapper:</p>
<pre>void foo(int);<br>value_initialized&lt;int&gt; const x ;<br>foo(x);<br></pre>
<p>But notice that this conversion operator is to <code>T&amp;</code> although
it is itself <code>const</code>. As a consequence, if <code>T</code> is
a non-<code>const</code> type, you can modify the wrapped object even from
within a constant wrapper:</p>
<pre>value_initialized&lt;int&gt; const x_c ;<br>int&amp; xr = x_c ; // OK, conversion to int&amp; available even though x_c is itself const.<br>xr = 2 ; </pre>
<p>The reason for this obscure behavior is that some commonly used compilers
just don't accept the following valid code:</p>
<pre>struct X<br>{<br> operator int&amp;() ;<br> operator int const&amp;() const ; <br>};<br>X x ;<br>(x == 1 ) ; // ERROR HERE!</pre>
<p>These compilers complain about ambiguity between the conversion operators.
This complaint is incorrect, but the only workaround that I know of is
to provide only one of them, which leads to the obscure behavior just explained.<br>
</p>
<h3>Recommended practice: The non-member get() idiom</h3>
<p>The obscure behavior of being able to modify a non-<code>const</code>
wrapped object from within a constant wrapper can be avoided if access to
the wrapped object is always performed with the <code>get()</code> idiom:</p>
<pre>value_initialized&lt;int&gt; x ;<br>get(x) = 1 ; // OK<br><br>value_initialized&lt;int const&gt; cx ;<br>get(x) = 1 ; // ERROR: Cannot modify a const object<br><br>value_initialized&lt;int&gt; const x_c ;<br>get(x_c) = 1 ; // ERROR: Cannot modify a const object<br><br>value_initialized&lt;int const&gt; const cx_c ;<br>get(cx_c) = 1 ; // ERROR: Cannot modify a const object<br></pre>
<h2><a name="initialized_value"><code>initialized_value</code></a></h2>
<pre>
namespace boost {
class initialized_value_t
{
public :
template &lt;class T&gt; operator T() const ;
};
initialized_value_t const initialized_value = {} ;
} // namespace boost
</pre>
<code>initialized_value</code> provides a convenient way to get
an initialized value: its conversion operator provides an appropriate
<em>value-initialized</em> object for any CopyConstructible type.
Suppose you need to have an initialized variable of type <code>T</code>.
You could do it as follows:
<pre>
T var = T();
</pre>
But as mentioned before, this form suffers from various compiler issues.
The template <code>value_initialized</code> offers a workaround:
<pre>
T var = get( value_initialized&lt;T&gt;() );
</pre>
Unfortunately both forms repeat the type name, which
is rather short now (<code>T</code>), but could of course be
more like <code>Namespace::Template&lt;Arg&gt;::Type</code>.
Instead, one could use <code>initialized_value</code> as follows:
<pre>
T var = initialized_value ;
</pre>

[1] Bjarne Stroustrup, Gabriel Dos Reis, and J. Stephen Adamczyk wrote
various papers, proposing to extend the support for brace-enclosed <em>initializer lists</em>
in the next version of C++.
This would allow a variable <code>var</code> of any DefaultConstructible type
<code>T</code> to be <em>value-initialized</em> by doing <code>T var = {}</code>.
