restart of branch, this is to include changes from trunk

[SVN r40545]
Added value_initialized<T> test, having T as aggregate POD struct. In the past, this would have triggered MSVC warning C4345; this warning is now disabled within value_init.hpp, changeset [40088]

+  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>

+

+      <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>

+    </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>

+  <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>

+  <h3>Design Notes</h3>

-<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>comments by Valentin Bonnard:</p>

-<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.

+<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>

+
+<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>
+

+    , 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>

-<h2 align="center">C++ Type traits</h2>
-<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 &quot;generic&quot;
-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&lt;&gt;::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&lt;T&gt;
-has a member <i>value</i> that is true only if T is void.</p>
-<pre>template &lt;typename T&gt; 
-struct is_void
-{ static const bool value = false; };
-
-template &lt;&gt; 
-struct is_void&lt;void&gt;
-{ 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&lt;T&gt;: 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 &lt;typename T&gt; 
-struct is_pointer 
-{ static const bool value = false; };
-
-template &lt;typename T&gt; 
-struct is_pointer&lt;T*&gt; 
-{ 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 &lt;<EFBFBD>&gt; 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 &lt;typename T&gt;
-class c{ /*details*/ };
-
-template &lt;typename T&gt;
-
-class c&lt;U&gt;{ /*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&lt;T&gt;. 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 &lt;typename T&gt; 
-struct remove_bounds
-{ typedef T type; };
-
-template &lt;typename T, std::size_t N&gt; 
-struct remove_bounds&lt;T[N]&gt;
-{ 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&lt;int[4][5]&gt;::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&lt;typename Iter1, typename Iter2&gt;
-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&lt;T&gt;::value</code>
-is true only if T has a trivial assignment operator. This class &quot;just
-works&quot; 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 &quot;safe&quot; 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 &quot;slow but safe version&quot;). Following that there is a specialisation
-for <i>copier&lt;true&gt;</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 &quot;optimised&quot; copy.</p>
-<p>In order to complete the implementation, what we need now is a version of
-copy, that calls <code>copier&lt;true&gt;::do_copy</code> if it is safe to use <font size="2" face="Courier New">memcpy</font>,
-and otherwise calls <code>copier&lt;false&gt;::do_copy</code> to do a
-&quot;generic&quot; 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&lt;Iter1&gt;::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 &quot;premature optimisation
-is the root of all evil&quot; [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 &quot;std::pair&quot;, omitting the
-comparision operators, default constructor, and template copy constructor for
-simplicity:</p>
-<pre>template &lt;typename T1, typename T2&gt; 
-struct pair 
-{
-  typedef T1 first_type;
-  typedef T2 second_type;
-
-  T1 first;
-  T2 second;
-
-  pair(const T1 &amp; nfirst, const T2 &amp; nsecond)
-  :first(nfirst), second(nsecond) { }
-};</pre>
-<p>Now, this &quot;pair&quot; 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 &quot;pair&quot; to hold non-reference types,
-references, and constant references:</p>

-<p>This allows us to build a primary template definition for &quot;pair&quot;

-types:</p>

-  typedef T2 second_type;

-       boost::add_reference&lt;const T2&gt;::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 &quot;pair&quot;, but to specialize &quot;pair&quot; 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>

-  <li>The type traits library is based upon contributions by Steve Cleary, Beman
-    Dawes, Howard Hinnant and John Maddock: it can be found at www.boost.org.</li>
-  <li>A scalar type is an arithmetic type (i.e. a built-in integer or floating

-    algo_opt_examples.cpp), the code was compiled with gcc 2.95 with all
-    optimisations turned on, tests were conducted on a 400MHz Pentium II machine
-    running Microsoft Windows 98.</li>
-  <li>John Maddock and Howard Hinnant have submitted a &quot;compressed_pair&quot;
-    library to Boost, which uses a technique similar to the one described here
-    to hold references. Their pair also uses type traits to determine if any of
-    the types are empty, and will derive instead of contain to conserve space --
-    hence the name &quot;compressed&quot;.</li>
-  <li>This is actually an issue with the C++ Core Language Working Group (issue
-    #106), submitted by Bjarne Stroustrup. The tentative resolution is to allow
-    a &quot;reference to a reference to T&quot; to mean the same thing as a
-    &quot;reference to T&quot;, but only in template instantiation, in a method
-    similar to multiple cv-qualifiers.</li>
-  <li>For those of you who are wondering why this shouldn't be const-qualified,
-    remember that references are always implicitly constant (for example, you
-    can't re-assign a reference). Remember also that &quot;const T &amp;&quot;
-    is something completely different. For this reason, cv-qualifiers on
-    template type arguments that are references are ignored.</li>

-    namespace cast {
-        // all synopsis below included here
-    }
-  using ::boost::cast::polymorphic_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.&nbsp; Downcasting means
-casting from a base class to a derived class.&nbsp; 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.&nbsp; 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.&nbsp;<b>&nbsp;</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.&nbsp; 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.&nbsp; It must also be used for crosscasts.&nbsp; It does an assert(
-dynamic_cast&lt;Derived&gt;(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.&nbsp; 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 &lt;class Derived, class Base&gt;
-inline Derived polymorphic_cast(Base* x);
-// Throws: std::bad_cast if ( dynamic_cast&lt;Derived&gt;(x) == 0 )
-// Returns: dynamic_cast&lt;Derived&gt;(x)
-
-template &lt;class Derived, class Base&gt;
-inline Derived polymorphic_downcast(Base* x);
-// Effects: assert( dynamic_cast&lt;Derived&gt;(x) == x );
-// Returns: static_cast&lt;Derived&gt;(x)</pre>
-</blockquote>
-<h3>polymorphic_downcast example</h3>
-<blockquote>
-  <pre>#include &lt;boost/cast.hpp&gt;
-...
-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&lt;Banana*&gt;(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&lt;&gt;::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&lt;typename Target, typename Source&gt;
-  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&lt;Target&gt;(arg)</pre>
-</blockquote>
-<h3>numeric_cast example</h3>
-<blockquote>
-  <pre>#include &lt;boost/cast.hpp&gt;
-using namespace boost::cast;
-
-void ariane(double vx)
-{
-    ...
-    unsigned short dx = numeric_cast&lt;unsigned short&gt;(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>

+			function templates, <STRONG>checked_delete</STRONG> and <STRONG>checked_array_delete</STRONG>, 
+			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>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

+      <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

+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;

+  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>
+

+
+      <td>The generator (0-ary function object) type being wrapped. The

+      "http://www.sgi.com/tech/stl/Generator.html">Generator</a>.</td>
+    </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=
+  "http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>
+  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>

+typename generator_iterator_generator&lt;Generator&gt;::type
+make_generator_iterator(Generator &amp; gen);
+</pre>
+  </blockquote>
+  <hr>
+
+  <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;

+private:
+  int state;
+};
+
+int main()
+{
+  my_generator gen;
+  boost::generator_iterator_generator&lt;my_generator&gt;::type it = boost::make_generator_iterator(gen);

+<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
+{

+
+<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

+    :
+    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_);
+  }

+
+  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>

-
-<p><a href="http://www.boost.org/people/dave_abrahams.htm">Dave
-Abrahams</a> started the library, coming up with the idea to use
-policy classes and how to handle the const/non-const iterator
-interactions. He also contributed the <tt>indirect_iterators</tt> and
-<tt>reverse_iterators</tt> classes.<br>
-
-<a href="http://www.boost.org/people/jeremy_siek.htm">Jeremy Siek</a>
-contributed <tt>transform_iterator</tt>, <tt>integer_range</tt>,
-and this documentation.
-
-<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-&gt;()</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:
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
-<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
-<PRE>
-template &lt;class Iterator, 
-          class ConstIterator, 
-          class Traits = std::iterator_traits&lt;Iterator&gt;,
-          class ConstTraits = std::iterator_traits&lt;ConstIterator&gt;, 
-          class Policies = default_iterator_policies&gt;
-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 &quot;boiler-plate&quot; for your own policy classes. The
-following is definition of the <tt>default_iterator_policies</tt>
-class:

-<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.

-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&lt;Reference&gt;</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>.

-      { 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.

-    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="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

-<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.

+<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.

+
+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.

+
+<TR>
+<TD><a

+<TD>The type of the container that we wish to iterate over. It must be 
+a model of the 
+<a href="http://www.sgi.com/tech/stl/Container.html"><tt>Container</tt></a>
+concept.
+</TD>
+</TR>
+</Table>
+
+<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)

+                               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.

+Class <tt>shared_container_iterator</tt> is meant primarily to return,

+
+<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.

+// next() and prior() several times. next() and prior() are very

-This is a utility function that makes it more convenient to work with

-An example of using the <TT>tie()</TT> function with the
-<TT>vertices()</TT> function, which returns a pair of
-type <TT>std::pair&lt;vertex_iterator,vertex_iterator&gt;</TT>.  The
-pair of iterators is assigned to the iterator variables <TT>i</TT> and
-<TT>end</TT>.

-
-<p>For those classes that are marked with a D or C, if compiler
-support is not provided, this type trait may return &quot;false&quot;
-when the correct value is actually &quot;true&quot;. The single
-exception to this rule is &quot;is_class&quot;, which attempts to
-guess whether or not T is really a class, and may return &quot;true&quot;
-when the correct value is actually &quot;false&quot;. This can
-happen if: T is a union, T is an enum, or T is a compiler-supplied
-scalar type that is not specialised for in these type traits.</p>
-
-<p><i>If there is no compiler support</i>, to ensure that these
-traits <i>always</i> return the correct values, specialise 'is_enum'
-for each user-defined enumeration type, 'is_union' for each user-defined
-union type, 'is_empty' for each user-defined empty composite type,
-and 'is_POD' for each user-defined POD type. The 'has_*' traits
-should also be specialized if the user-defined type has those
-traits and is <i>not</i> a POD.</p>
-
-<p>The following rules are automatically enforced:</p>
-
-<p>is_enum implies is_POD</p>
-
-<p>is_POD implies has_*</p>
-
-<p>This means, for example, if you have an empty POD-struct, just
-specialize is_empty and is_POD, which will cause all the has_* to
-also return true.</p>

+<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. <code>value_initialized</code> provides
+a solution   with consistent syntax for value   initialization of scalar,
+union and class   types. <br>
+  </p>
+        
+<h2><a name="intro"></a>Introduction</h2>
+     
+<p>The C++ standard [<a href="#references">1</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">2</a>] types are zero-initialized, while 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 default-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 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>

+ 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><i>(but recall that the current C++ Standard states that '()' invokes default-initialization,
+not value-initialization)</i></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-initialied</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(*)()<br>int y ( int() ) ; // decalares function int(*)( 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><code>This is the solution supplied by the value_initialized&lt;&gt; template
+     class.</code></p>
+                   
+<h2><a name="types"></a>Types</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><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>
+                   
+<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>
