+  Collection</h1>
+
+  <h3>Description</h3>
+
+  <p>A Collection is a <i>concept</i> similar to the STL <a href=
+  "http://www.sgi.com/tech/stl/Container.html">Container</a> concept. A
+  Collection provides iterators for accessing a range of elements and
+  provides information about the number of elements in the Collection.
+  However, a Collection has fewer requirements than a Container. The
+  motivation for the Collection concept is that there are many useful
+  Container-like types that do not meet the full requirements of Container,
+  and many algorithms that can be written with this reduced set of
+  requirements. To summarize the reduction in requirements:</p>
+
+  <ul>
+    <li>It is not required to "own" its elements: the lifetime of an element
+    in a Collection does not have to match the lifetime of the Collection
+    object, though the lifetime of the element should cover the lifetime of
+    the Collection object.</li>
+
+    <li>The semantics of copying a Collection object is not defined (it could
+    be a deep or shallow copy or not even support copying).</li>
+
+    <li>The associated reference type of a Collection does not have to be a
+    real C++ reference.</li>
+  </ul>Because of the reduced requirements, some care must be taken when
+  writing code that is meant to be generic for all Collection types. In
+  particular, a Collection object should be passed by-reference since
+  assumptions can not be made about the behaviour of the copy constructor.

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

+
+    <tr>

+

+      <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>

+  <h2><a name="concept:MultiPassInputIterator" id=
+  "concept:MultiPassInputIterator"></a> Multi-Pass Input Iterator</h2>
+
+  <p>This concept is a refinement of <a href=
+  "http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>, adding
+  the requirements that the iterator can be used to make multiple passes
+  through a range, and that if <tt>it1 == it2</tt> and <tt>it1</tt> is
+  dereferenceable then <tt>++it1 == ++it2</tt>. The Multi-Pass Input Iterator
+  is very similar to the <a href=
+  "http://www.sgi.com/tech/stl/ForwardIterator.html">Forward Iterator</a>.
+  The only difference is that a <a href=
+  "http://www.sgi.com/tech/stl/ForwardIterator.html">Forward Iterator</a>
+  requires the <tt>reference</tt> type to be <tt>value_type&amp;</tt>,
+  whereas MultiPassInputIterator is like <a href=
+  "http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a> in that
+  the <tt>reference</tt> type merely has to be convertible to
+  <tt>value_type</tt>.</p>
+
+  <h3>Design Notes</h3>
+
+  <p>comments by Valentin Bonnard:</p>
+
+  <p>I think that introducing Multi-Pass Input Iterator isn't the right
+  solution. Do you also want to define Multi-Pass Bidirectionnal Iterator and
+  Multi-Pass Random Access Iterator ? I don't, definitly. It only confuses
+  the issue. The problem lies into the existing hierarchy of iterators, which
+  mixes movabillity, modifiabillity and lvalue-ness, and these are clearly
+  independant.</p>
+
+  <p>The terms Forward, Bidirectionnal and Random Access are about
+  movabillity and shouldn't be used to mean anything else. In a completly
+  orthogonal way, iterators can be immutable, mutable, or neither. Lvalueness
+  of iterators is also orthogonal with immutabillity. With these clean
+  concepts, your Multi-Pass Input Iterator is just called a Forward
+  Iterator.</p>
+
+  <p>Other translations are:<br>
+  std::Forward Iterator -&gt; ForwardIterator &amp; Lvalue Iterator<br>
+  std::Bidirectionnal Iterator -&gt; Bidirectionnal Iterator &amp; Lvalue
+  Iterator<br>
+  std::Random Access Iterator -&gt; Random Access Iterator &amp; Lvalue
+  Iterator<br></p>
+
+  <p>Note that in practice the only operation not allowed on my Forward
+  Iterator which is allowed on std::Forward Iterator is <tt>&amp;*it</tt>. I
+  think that <tt>&amp;*</tt> is rarely needed in generic code.</p>
+
+  <p>reply by Jeremy Siek:</p>
+
+  <p>The above analysis by Valentin is right on. Of course, there is the
+  problem with backward compatibility. The current STL implementations are
+  based on the old definition of Forward Iterator. The right course of action
+  is to get Forward Iterator, etc. changed in the C++ standard. Once that is
+  done we can drop Multi-Pass Input Iterator.<br></p>

+
+<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

+
+<h2><a name="rationale">Rationale</a></h2>
+
+<p>When developing a class, sometimes a base class needs to be
+initialized with a member of the current class.  As a na&iuml;ve
+example:</p>
+
+<blockquote><pre>
+#include &lt;streambuf&gt;  <i>// for std::streambuf</i>
+#include &lt;ostream&gt;    <i>// for std::ostream</i>
+
+class fdoutbuf
+    : public std::streambuf
+{
+public:
+    explicit fdoutbuf( int fd );
+    //...
+};
+
+class fdostream
+    : public std::ostream
+{
+protected:
+    fdoutbuf buf;
+public:
+    explicit fdostream( int fd )
+        : buf( fd ), std::ostream( &amp;buf )
+        {}
+    //...
+};
+</pre></blockquote>
+
+<p>This is undefined because C++'s initialization order mandates that
+the base class is initialized before the member it uses.  <a
+href="http://www.moocat.org">R. Samuel Klatchko</a> developed a way
+around this by using the initialization order in his favor.  Base
+classes are intialized in order of declaration, so moving the desired
+member to another base class, that is initialized before the desired
+base class, can ensure proper initialization.</p>
+
+<p>A custom base class can be made for this idiom:</p>
+
+<blockquote><pre>
+#include &lt;streambuf&gt;  <i>// for std::streambuf</i>
+#include &lt;ostream&gt;    <i>// for std::ostream</i>
+
+class fdoutbuf
+    : public std::streambuf
+{
+public:
+    explicit fdoutbuf( int fd );
+    //...
+};
+
+struct fdostream_pbase
+{
+    fdoutbuf sbuffer;
+
+    explicit fdostream_pbase( int fd )
+        : sbuffer( fd )
+        {}
+};
+
+class fdostream
+    : private fdostream_pbase
+    , public std::ostream
+{
+    typedef fdostream_pbase  pbase_type;
+    typedef std::ostream     base_type;
+
+public:
+    explicit fdostream( int fd )
+        : pbase_type( fd ), base_type( &amp;sbuffer )
+        {}
+    //...
+};
+</pre></blockquote>
+
+<p>Other projects can use similar custom base classes.  The technique
+is basic enough to make a template, with a sample template class in
+this library.  The main template parameter is the type of the enclosed
+member.  The template class has several (explicit) constructor member
+templates, which implicitly type the constructor arguments and pass them
+to the member.  The template class uses implicit copy construction and
+assignment, cancelling them if the enclosed member is non-copyable.</p>
+
+<p>Manually coding a base class may be better if the construction
+and/or copying needs are too complex for the supplied template class,
+or if the compiler is not advanced enough to use it.</p>
+
+<p>Since base classes are unnamed, a class cannot have multiple (direct)
+base classes of the same type.  The supplied template class has an
+extra template parameter, an integer, that exists solely to provide type
+differentiation.  This parameter has a default value so a single use of a
+particular member type does not need to concern itself with the integer.</p>
+
+<h2><a name="synopsis">Synopsis</a></h2>
+
+<blockquote><pre>
+#ifndef BOOST_BASE_FROM_MEMBER_MAX_ARITY
+#define BOOST_BASE_FROM_MEMBER_MAX_ARITY  10
+#endif
+
+template &lt; typename MemberType, int UniqueID = 0 &gt;
+class boost::base_from_member
+{
+protected:
+    MemberType  member;
+
+    base_from_member();
+
+    template&lt; typename T1 &gt;
+    explicit  base_from_member( T1 x1 );
+
+    template&lt; typename T1, typename T2 &gt;
+    base_from_member( T1 x1, T2 x2 );
+
+    //...
+
+    template&lt; typename T1, typename T2, typename T3, typename T4,
+     typename T5, typename T6, typename T7, typename T8, typename T9,
+     typename T10 &gt;
+    base_from_member( T1 x1, T2 x2, T3 x3, T4 x4, T5 x5, T6 x6, T7 x7,
+     T8 x8, T9 x9, T10 x10 );
+};
+</pre></blockquote>
+
+<p>The class template has a first template parameter
+<var>MemberType</var> representing the type of the based-member.
+It has a last template parameter <var>UniqueID</var>, that is an
+<code>int</code>, to differentiate between multiple base classes that use
+the same based-member type.  The last template parameter has a default
+value of zero if it is omitted.  The class template has a protected
+data member called <var>member</var> that the derived class can use
+for later base classes (or itself).</p>
+
+<p>There is a default constructor and several constructor member
+templates.  These constructor templates can take as many arguments
+(currently up to ten) as possible and pass them to a constructor of
+the data member.  Since C++ does not allow any way to explicitly state
+the template parameters of a templated constructor, make sure that
+the arguments are already close as possible to the actual type used in
+the data member's desired constructor.</p>
+
+<p>The <var>BOOST_BASE_FROM_MEMBER_MAX_ARITY</var> macro constant specifies
+the maximum argument length for the constructor templates.  The constant
+may be overridden if more (or less) argument configurations are needed.  The
+constant may be read for code that is expandable like the class template and
+needs to maintain the same maximum size.  (Example code would be a class that
+uses this class template as a base class for a member with a flexible set of
+constructors.)</p>
+
+<h2><a name="usage">Usage</a></h2>
+
+<p>With the starting example, the <code>fdoutbuf</code> sub-object needs
+to be encapsulated in a base class that is inheirited before
+<code>std::ostream</code>.</p>
+
+<blockquote><pre>
+#include &lt;boost/utility/base_from_member.hpp&gt;
+
+#include &lt;streambuf&gt;  <i>// for std::streambuf</i>
+#include &lt;ostream&gt;    <i>// for std::ostream</i>
+
+class fdoutbuf
+    : public std::streambuf
+{
+public:
+    explicit fdoutbuf( int fd );
+    //...
+};
+
+class fdostream
+    : private boost::base_from_member&lt;fdoutbuf&gt;
+    , public std::ostream
+{
+    // Helper typedef's
+    typedef boost::base_from_member&lt;fdoutbuf&gt;  pbase_type;
+    typedef std::ostream                        base_type;
+
+public:
+    explicit fdostream( int fd )
+        : pbase_type( fd ), base_type( &amp;member )
+        {}
+    //...
+};
+</pre></blockquote>
+
+<p>The base-from-member idiom is an implementation detail, so it
+should not be visible to the clients (or any derived classes) of
+<code>fdostream</code>.  Due to the initialization order, the
+<code>fdoutbuf</code> sub-object will get initialized before the
+<code>std::ostream</code> sub-object does, making the former
+sub-object safe to use in the latter sub-object's construction.  Since the
+<code>fdoutbuf</code> sub-object of the final type is the only sub-object
+with the name &quot;member,&quot; that name can be used
+unqualified within the final class.</p>
+
+<h2><a name="example">Example</a></h2>
+
+<p>The base-from-member class templates should commonly involve
+only one base-from-member sub-object, usually for attaching a
+stream-buffer to an I/O stream.  The next example demonstrates how
+to use multiple base-from-member sub-objects and the resulting
+qualification issues.</p>
+
+<blockquote><pre>
+#include &lt;boost/utility/base_from_member.hpp&gt;

+    , base1_type( pbase3_type::member, pbase1_type::member )
+    , base2_type( pbase2_type::member )
+{
+    //...
+}
+</pre></blockquote>
+
+<p>The final class has multiple sub-objects with the name
+&quot;member,&quot; so any use of that name needs qualification by
+a name of the appropriate base type.  (Using <code>typedef</code>s
+ease mentioning the base types.)  However, the fix introduces a new
+problem when a pointer is needed.  Using the address operator with
+a sub-object qualified with its class's name results in a pointer-to-member
+(here, having a type of <code>an_int boost::base_from_member&lt;an_int,
+0&gt; :: *</code>) instead of a pointer to the member (having a type of
+<code>an_int *</code>).  The new problem is fixed by qualifying the
+sub-object with &quot;<code>this-&gt;</code>,&quot; and is needed just
+for pointers, and not for references or values.</p>
+
+<p>There are some argument conversions in the initialization.  The
+constructor argument for <code>pbase0_type</code> is converted from
+<code>double</code> to <code>float</code>.  The first constructor
+argument for <code>pbase2_type</code> is converted from <code>int</code>
+to <code>double</code>.  The second constructor argument for
+<code>pbase3_type</code> is a special case of necessary conversion; all
+forms of the null-pointer literal in C++ also look like compile-time
+integral expressions, so C++ always interprets such code as an integer
+when it has overloads that can take either an integer or a pointer.  The
+last conversion is necessary for the compiler to call a constructor form
+with the exact pointer type used in <code>switcher</code>'s constructor.</p>

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

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

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

+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>

+
+<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>

+
+<A NAME="sec:using_enable_if"></A>
+The <TT>enable_if</TT> templates are defined in
+<TT>boost/utility/enable_if.hpp</TT>, which is included by <TT>boost/utility.hpp</TT>.<BR>
+<BR>
+The <TT>enable_if</TT> template can be used either as the return type, or as an 
+extra argument. For example, the <TT>foo</TT> function in the previous section could also be written
+as:
+<PRE>template &lt;class T&gt;
+T foo(T t, typename enable_if&lt;boost::is_arithmetic&lt;T&gt; &gt;::type* dummy = 0); 
+
+</PRE>Hence, an extra parameter of type <TT>void*</TT> is added, but it is given 
+a default value to keep the parameter hidden from client code.
+Note that the second template argument was not given to <TT>enable_if</TT>, as the default 
+<TT>void</TT> gives the desired behavior.<BR>
+<BR>
+Whether to write the enabler as an argument or within the return type is
+largely a matter of taste, but for certain functions, only one
+alternative is possible:
+<UL><LI>
+Operators have a fixed number of arguments, thus <TT>enable_if</TT> must be used in the return type.
+<LI>Constructors and destructors do not have a return type; an extra argument is the only option.
+<LI>There does not seem to be a way to specify an enabler for a conversion operator. Converting constructors,
+however, can have enablers as extra default arguments.
+</UL>
+<!--TOC subsection Enabling template class specializations-->
+
+<H3><A NAME="htoc6">3.1</A>&nbsp;&nbsp;Enabling template class specializations</H3><!--SEC END -->
+
+<A NAME="sec:enable_if_classes"></A>
+Class template specializations can be enabled or disabled with <TT>enable_if</TT>.
+One extra template parameter needs to be added for the enabler expressions.
+This parameter has the default value <TT>void</TT>.
+For example:
+<PRE>template &lt;class T, class Enable = void&gt; 
+class A { ... };
+
+template &lt;class T&gt;
+class A&lt;T, typename enable_if&lt;is_integral&lt;T&gt; &gt;::type&gt; { ... };
+
+template &lt;class T&gt;
+class A&lt;T, typename enable_if&lt;is_float&lt;T&gt; &gt;::type&gt; { ... };
+
+</PRE>Instantiating <TT>A</TT> with any integral type matches the first specialization,
+whereas any floating point type matches the second one. All other types
+match the primary template.
+The condition can be any compile-time boolean expression that depends on the 
+template arguments of the class.
+Note that again, the second argument to <TT>enable_if</TT> is not needed; the default (<TT>void</TT>) 
+is the correct value.<BR>
+<BR>
+<!--TOC subsection Overlapping enabler conditions-->
+
+<H3><A NAME="htoc7">3.2</A>&nbsp;&nbsp;Overlapping enabler conditions</H3><!--SEC END -->
+
+<A NAME="sec:overlapping_conditions"></A>
+Once the compiler has examined the enabling conditions and included the
+function into the overload resolution set, normal C++ overload resolution 
+rules are used to select the best matching function.
+In particular, there is no ordering between enabling conditions.
+Function templates with enabling conditions that are not mutually exclusive can 
+lead to ambiguities. For example:
+<PRE>template &lt;class T&gt;
+typename enable_if&lt;boost::is_integral&lt;T&gt;, void&gt;::type 
+foo(T t) {}
+
+template &lt;class T&gt;
+typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, void&gt;::type 
+foo(T t) {}
+
+</PRE>
+All integral types are also arithmetic. Therefore, say, for the call <TT>foo(1)</TT>,
+both conditions are true and both functions are thus in the overload resolution set.
+They are both equally good matches and thus ambiguous.
+Of course, more than one enabling condition can be simultaneously true as long as 
+other arguments disambiguate the functions.<BR>
+<BR>
+The above discussion applies to using <TT>enable_if</TT> in class template
+partial specializations as well.<BR>
+<BR>
+<!--TOC subsection Lazy <TT>enable_if</TT>-->
+
+<H3><A NAME="htoc8">3.3</A>&nbsp;&nbsp;Lazy <TT>enable_if</TT></H3><!--SEC END -->
+
+<A NAME="sec:enable_if_lazy"></A>
+In some cases it is necessary to avoid instantiating part of a
+function signature unless an enabling condition is true. For example:
+<PRE>template &lt;class T, class U&gt; class mult_traits;
+
+template &lt;class T, class U&gt;
+typename enable_if&lt;is_multipliable&lt;T, U&gt;, typename mult_traits&lt;T, U&gt;::type&gt;::type
+operator*(const T&amp; t, const U&amp; u) { ... }
+
+</PRE>Assume the class template <TT>mult_traits</TT> is a traits class defining 
+the resulting type of a multiplication operator. The <TT>is_multipliable</TT> traits
+class specifies for which types to enable the operator. Whenever
+<TT>is_multipliable&lt;A, B&gt;::value</TT> is <TT>true</TT> for some types <TT>A</TT> and <TT>B</TT>,
+then <TT>mult_traits&lt;A, B&gt;::type</TT> is defined.<BR>
+<BR>
+Now, trying to invoke (some other overload) of <TT>operator*</TT> with, say, operand types <TT>C</TT> and <TT>D</TT> 
+for which <TT>is_multipliable&lt;C, D&gt;::value</TT> is <TT>false</TT> 
+and <TT>mult_traits&lt;C, D&gt;::type</TT> is not defined is an error on some compilers. 
+The SFINAE principle is not applied because
+the invalid type occurs as an argument to another template. The <TT>lazy_enable_if</TT> 
+and <TT>lazy_disable_if</TT> templates (and their <TT>_c</TT> versions) can be used in such
+situations:
+<PRE>template&lt;class T, class U&gt;
+typename lazy_enable_if&lt;is_multipliable&lt;T, U&gt;, mult_traits&lt;T, U&gt; &gt;::type
+operator*(const T&amp; t, const U&amp; u) { ... }
+
+</PRE>The second argument of <TT>lazy_enable_if</TT> must be a class type
+that defines a nested type named <TT>type</TT> whenever the first
+parameter (the condition) is true.<BR>
+<BR>
+<!--TOC paragraph Note-->
+
+<H5>Note</H5><!--SEC END -->
+
+Referring to one member type or static constant in a traits class
+causes all of the members (type and static constant) of that
+specialization to be instantiated. Therefore, if your traits classes
+can sometimes contain invalid types, you should use two distinct
+templates for describing the conditions and the type mappings. In the
+above example, <TT>is_multipliable&lt;T, U&gt;::value</TT> defines when
+<TT>mult_traits&lt;T, U&gt;::type</TT> is valid.<BR>
+<BR>
+<!--TOC subsection Compiler workarounds-->
+
+<H3><A NAME="htoc9">3.4</A>&nbsp;&nbsp;Compiler workarounds</H3><!--SEC END -->
+
+<A NAME="sec:workarounds"></A>
+Some compilers flag functions as ambiguous if the only distinguishing factor is a different 
+condition in an enabler (even though the functions could never be ambiguous). For example,
+some compilers (e.g. GCC 3.2) diagnose the following two functions as ambiguous:
+<PRE>template &lt;class T&gt;
+typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
+foo(T t);
+
+template &lt;class T&gt;
+typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
+foo(T t);
+
+</PRE>Two workarounds can be applied:
+<UL><LI>
+Use an extra dummy parameter which disambiguates the functions. Use a default value for
+it to hide the parameter from the caller. For example:
+<PRE>template &lt;int&gt; struct dummy { dummy(int) {} };
+
+template &lt;class T&gt;
+typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
+foo(T t, dummy&lt;0&gt; = 0);
+
+template &lt;class T&gt;
+typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
+foo(T t, dummy&lt;1&gt; = 0);
+</PRE><BR>
+<BR>
+<LI>Define the functions in different namespaces and bring them into a common
+namespace with <TT>using</TT> declarations:
+<PRE>namespace A {
+  template &lt;class T&gt;
+  typename enable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
+  foo(T t);
+}
+
+namespace B {
+  template &lt;class T&gt;
+  typename disable_if&lt;boost::is_arithmetic&lt;T&gt;, T&gt;::type 
+  foo(T t);
+}
+
+using A::foo;
+using B::foo;
+
+</PRE>
+Note that the second workaround above cannot be used for member
+templates. On the other hand, operators do not accept extra arguments,
+which makes the first workaround unusable. As the net effect,
+neither of the workarounds are of assistance for templated operators that
+need to be defined as member functions (assignment and
+subscript operators).

+
+  <h1>Generator Iterator Adaptor</h1>
+
+  <p>Defined in header <a href=
+  "../../boost/generator_iterator.hpp">boost/generator_iterator.hpp</a></p>
+
+  <p>The generator iterator adaptor makes it easier to create custom input
+  iterators from 0-ary functions and function objects. The adaptor takes a
+  <a href="http://www.sgi.com/tech/stl/Generator.html">Generator</a> and
+  creates a model of <a href=
+  "http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>. Each
+  increment retrieves an item from the generator and makes it available to be
+  retrieved by dereferencing. The motivation for this iterator is that some
+  concepts can be more naturally expressed as a generator, while most STL
+  algorithms expect an iterator. An example is the <a href=
+  "../random/index.html">Random Number</a> library.</p>
+
+  <h2>Synopsis</h2>
+
+  <blockquote>
+    <pre>
+namespace boost {
+  template &lt;class Generator&gt;
+  class generator_iterator_policies;
+
+  template &lt;class Generator&gt;
+  class generator_iterator_generator;
+
+  template &lt;class Generator&gt;
+  typename generator_iterator_generator&lt;Generator&gt;::type
+  make_generator_iterator(Generator &amp; gen);
+}
+</pre>
+  </blockquote>
+  <hr>
+
+  <h2>The Generator Iterator Generator Class</h2>
+
+  <p>The class generator_iterator_generator is a helper class whose purpose
+  is to construct a generator iterator type. The template parameter for this
+  class is the Generator function object type that is being wrapped. The
+  generator iterator adaptor only holds a reference (or pointer) to the
+  function object, therefore the function object must outlive the generator
+  iterator adaptor constructed from it.</p>
+  <pre>
+template &lt;class Generator&gt;
+class generator_iterator_generator
+{
+public:
+  typedef <i>unspecified</i> type; // the resulting generator iterator type 
+}
+</pre>
+
+  <h3>Template Parameters</h3>
+
+  <table border summary="">
+    <tr>
+      <th>Parameter</th>
+
+      <th>Description</th>
+    </tr>
+
+    <tr>
+      <td><tt><a href=
+      "http://www.sgi.com/tech/stl/Generator.html">Generator</a></tt></td>
+
+      <td>The generator (0-ary function object) type being wrapped. The
+      return type of the function must be defined as
+      <tt>Generator::result_type</tt>. The function object must be a model of
+      <a href=
+      "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>
+template &lt;class Generator&gt;
+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;
+
+class my_generator
+{
+public:
+  typedef int result_type;
+  my_generator() : state(0) { }
+  int operator()() { return ++state; }
+private:
+  int state;
+};
+
+int main()
+{
+  my_generator gen;
+  boost::generator_iterator_generator&lt;my_generator&gt;::type it = boost::make_generator_iterator(gen);
+  for(int i = 0; i &lt; 10; ++i, ++it)
+    std::cout &lt;&lt; *it &lt;&lt; std::endl;

+<H2><A NAME="mot"></A>Motivation</H2>
+
+<p>Suppose we have a class</p>
+<pre>struct X
+{
+  X ( int, std:::string ) ;
+} ;</pre>
+<p>And a container for it which supports an empty state (that is, which can contain zero objects):</p>
+<pre>struct C
+{
+   C() : contained_(0) {}
+  ~C() { delete contained_ ; }
+  X* contained_ ;
+} ;</pre>
+<p>A container designed to support an empty state typically doesn't require the contained type to be DefaultConstructible,
+but it typically requires it to be CopyConstructible as a mechanism to
+initialize the object to store:</p>
+<pre>struct C
+{
+   C() : contained_(0) {}
+   C ( X const& v ) : contained_ ( new X(v) ) {}
+  ~C() { delete contained_ ; }
+  X* contained_ ;
+} ;</pre>
+<p>There is a subtle problem with this: since the mechanism used to initialize the stored object is copy construction,
+there must exist a previously constructed source object to copy from. This
+object is likely to be temporary and serve no purpose besides being the source</p>
+<pre>void foo()
+{
+  // Temporary object created.
+  C c( X(123,"hello") ) ;
+}
+</pre>
+<p>A solution to this problem is to support direct construction of the contained
+object right in the container's storage.<br>
+In this scheme, the user supplies the arguments for the X constructor
+directly to the container:</p>
+<pre>struct C
+{
+   C() : contained_(0) {}
+   C ( X const& v ) : contained_ ( new X(v) ) {}
+   C ( int a0, std::string a1 ) : contained_ ( new X(a0,a1) ) {}
+  ~C() { delete contained_ ; }
+  X* contained_ ;
+} ;</pre>
+<pre>void foo()
+{
+  // Wrapped object constructed in-place
+  // No temporary created.
+  C c(123,"hello") ;
+}
+</pre>
+<p>Clearly, this solution doesn't scale well since the container must duplicate all the constructor overloads from the contained type
+(at least all those which are to be supported directly in the container).</p>
+
+<H2><A NAME="framework"></A>Framework</H2>
+<p>
+This library proposes a framework to allow some containers to directly contruct contained objects in-place without requiring
+the entire set of constructor overloads ftom the contained type. It also allows the container to remove the CopyConstuctible
+requirement from the contained type since objects can be directly constructed in-place without need of a copy.<br>
+The only requirement on the container is that it must provide proper storage (that is, correctly aligned and sized).
+Naturally, the container will typically support uninitialized storage to avoid the in-place construction to override
+a fully-constructed object (as this would defeat the purpose of in-place construction)
+</p>
+<p>For this purpose, the framework provides two families of classes collectively called: InPlaceFactories and TypedInPlaceFactories.<br>
+Essentially, these classes hold a sequence of actual parameters and a method to contruct an object in place using these parameters.
+Each member of the family differs only in the number (and type) of the parameter list. The first family
+takes the type of the object to construct directly in method provided for that
+purpose, whereas the second family incorporates that type in the factory class
+itself..</p>
+<p>From the container POV, using the framework amounts to calling the factory's method to contruct the object in place.
+From the user POV, it amounts to creating the right factory object to hold the parameters and pass it to the container.<br>
+The following simplified example shows the basic idea. A complete example follows the formal specification of the framework:</p>
+<pre>struct C
+{
+   template&lt;class InPlaceFactory&gt;
+   C ( InPlaceFactory const& aFactoty )
+    :
+    contained_ ( uninitialized_storage() )
+   {
+     aFactory.template apply&lt;X&gt;(contained_);
+   }
+
+  ~C() 
+  { 
+    contained_ -> X::~X();
+    delete[] contained_ ; 
+  }
+
+  char* uninitialized_storage() { return new char[sizeof(X)] ; }
+
+  char* contained_ ;
+} ;
+
+void foo()
+{
+  C c( in_place(123,"hello") ) ;
+}
+</pre>
+
+<HR>
+
+<H2><A NAME="specification">Specification</A></H2>
+
+<p>The following is the first member of the family of 'in_place_factory' classes, along with its corresponding helper template function.
+The rest of the family varies only in the number and type of template (and constructor) parameters.</p>
+<PRE>namespace boost {
+
+struct in_place_factory_base {} ;
+
+template&lt;class A0&gt;
+class in_place_factory : public in_place_factory_base
+{
+  public:</PRE>
+
+<PRE>    in_place_factory ( A0 const& a0 ) : m_a0(a0) {}
+
+    template&lt; class T &gt;
+    void apply ( void* address ) const
+    {
+      new (address) T(m_a0);
+    }
+
+  private:</PRE>
+
+<PRE>    A0 const& m_a0 ;
+} ;
+
+template&lt;class A0&gt;
+in_place_factory&lt;A0&gt; in_place ( A0 const& a0 )
+{
+  return in_place_factory&lt;A0&gt;(a0);
+}
+</PRE>
+
+<p>Similarly, the following is the first member of the family of 'typed_in_place_factory' classes, along with its corresponding
+helper template function. The rest of the family varies only in the number and type of template (and constructor) parameters.</p>
+<PRE>namespace boost {
+
+struct typed_in_place_factory_base {} ;
+
+template&lt;class T, class A0&gt;
+class typed_in_place_factory : public typed_in_place_factory_base
+{
+  public:</PRE>
+
+<PRE>    typed_in_place_factory ( A0 const& a0 ) : m_a0(a0) {}
+
+    void apply ( void* address ) const
+    {
+      new (address) T(m_a0);
+    }
+
+  private:</PRE>
+
+<PRE>    A0 const& m_a0 ;
+} ;
+
+template&lt;class T, class A0&gt;
+typed_in_place_factory&lt;A0&gt; in_place ( A0 const& a0 )
+{
+  return typed_in_place_factory&lt;T,A0&gt;(a0);
+}</PRE>
+
+<PRE>}
+</PRE>
+
+<p>As you can see, the 'in_place_factory' and 'typed_in_place_factory' template classes varies only in the way they specify
+the target type: in the first family, the type is given as a template argument to the apply member function while in the
+second it is given directly as part of the factory class.<br>
+When the container holds a unique non-polymorphic type (such as the case of Boost.Optional), it knows the exact dynamic-type
+of the contained object and can pass it to the apply() method of a (non-typed) factory.
+In this case, end users can use an 'in_place_factory' instance which can be constructed without the type of the object to construct.<br>
+However, if the container holds heterogeneous or polymorphic objects (such as the case of Boost.Variant), the dynamic-type
+of the object to be constructed must be known by the factory itslef. In this case, end users must use a 'typed_in_place_factory'
+instead.</p>
+
+<HR>
+
+<h2><A NAME="container-usage">Container-side Usage</a></h2>
+
+<p>As shown in the introductory simplified example, the container class must
+contain methods that accept an instance of
+these factories and pass the object's storage to the factory's apply method.<br>
+However, the type of the factory class cannot be completly specified in the container class because that would
+defeat the whole purpose of the factories which is to allow the container to accept a variadic argument list
+for the constructor of its contained object.<br>
+The correct function overload must be based on the only distinctive and common
+characteristic of all the classes in each family, the base class.<br>
+Depending on the container class, you can use 'enable_if' to generate the right overload, or use the following
+dispatch technique (used in the Boost.Optional class):
+</p>
+<pre>struct C
+{
+   C() : contained_(0) {}
+   C ( X const& v ) : contained_ ( new X(v) ) {}
+
+   template&lt;class Expr&gt
+   C ( Expr const& expr )
+    :
+    contained_ ( uninitialized_storage() )
+   {
+    construct(expr,&expr)
+   }
+
+  ~C() { delete contained_ ; }
+
+  template&lt;class InPlaceFactory&gt;
+  void construct ( InPlaceFactory const& aFactory, boost::in_place_factory_base* )
+  {
+    aFactory.template apply&lt;X&gt;(contained_);
+  }
+
+  template&lt;class TypedInPlaceFactory&gt;
+  void construct ( TypedInPlaceFactory const& aFactory, boost::typed_in_place_factory_base* )
+  {
+    aFactory.apply(contained_);
+  }
+
+  X* uninitialized_storage() { return static_cast&lt;X*&gt;(new char[sizeof(X)]) ; }
+
+  X* contained_ ;
+} ;
+</pre>
+
+<hr>
+
+<h2><A NAME="user-usage">User-side Usage</a></h2>
+
+<p>End users pass to the container an instance of a factory object holding the actual parameters needed to construct the
+contained object directly within the container. For this, the helper template function 'in_place' is used.<br>
+The call 'in_place(a0,a1,a2,...,an)' constructs a (non-typed) 'in_place_factory' instance with the given argument list.<br>
+The call 'in_place&lt;T&gt;(a0,a1,a2,...,an)' constructs a 'typed_in_place_factory' instance with the given argument list for the
+type 'T'.</p>
+<pre>void foo()
+{
+  C a( in_place(123,"hello") ) ;    // in_place_factory passed
+  C b( in_place&lt;X&gt;(456,"world") ) ; // typed_in_place_factory passed
+}

+//  Revision History
+//  03 Apr 08 Added convertible_to_bool (Daniel Frey)
+//  01 Oct 01 Added tests for "left" operators
+//            and new grouped operators. (Helmut Zeisel)
+//  20 May 01 Output progress messages.  Added tests for new operator
+//            templates.  Updated random number generator.  Changed tests to
+//            use Boost Test Tools library.  (Daryle Walker)
+//  04 Jun 00 Added regression test for a bug I found (David Abrahams)
+//  17 Jun 00 Fix for broken compilers (Aleksey Gurtovoy)
+//  ?? ??? 00 Major update to randomly test all one- and two- argument forms by
+//            wrapping integral types and comparing the results of operations
+//            to the results for the raw types (David Abrahams)
+//  12 Dec 99 Minor update, output confirmation message.

+<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>
+
+<TR>
+<TD><a
+href="http://www.sgi.com/tech/stl/Container.html"><tt>Container</tt></a></TD>
+<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)

+<h2><a name="make_iterator">The Shared Container Iterator Object Generator</a></h2>
+
+<pre>
+template &lt;typename Container&gt;
+shared_container_iterator&lt;Container&gt;
+make_shared_container_iterator(Container::iterator base,
+                               boost::shared_ptr&lt;Container&gt; const&amp; container)
+</pre>
+
+This function provides an alternative to directly constructing a
+shared container iterator.  Using the object generator, a shared
+container iterator can be created and passed to a function without
+explicitly specifying its type.
+
+<h3>Example</h3>
+
+This example, similar to the previous, uses 
+<tt>make_shared_container_iterator()</tt> to create the iterators.

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

+std::make_pair(make_shared_container_iterator(container-&gt;begin(),container),

+
+<h3>Example</h3>
+
+In the following example, a range of values is returned as a pair of

+  <body>
+    <!-- Page header -->
+    <img src="../../boost.png" alt="C++ Boost" align="middle" width="277" height="86"/>
+    <h1>Swap</h1>
+    
+    <p>
+      <tt>template&lt;class T&gt; void swap(T&amp; <em>left</em>, T&amp; <em>right</em>);</tt>
+    </p>
+     
+    <!-- Intoduction -->
+    <p>
+      The template function <tt>boost::swap</tt> allows the values of two variables to be swapped, using argument dependent lookup to select a specialized swap function if available. If no specialized swap function is available, <tt>std::swap</tt> is used.
+    </p>
+    
+    <!-- Rationale -->
+    <h2>Rationale</h2>
+    <p>
+      The generic <tt>std::swap</tt> function requires that the elements to be swapped are assignable and copy constructible. It is usually implemented using one copy construction and two assignments - this is often both unnecessarily restrictive and unnecessarily slow. In addition, where the generic swap implementation provides only the basic guarantee, specialized swap functions are often able to provide the no-throw exception guarantee (and it is considered best practice to do so where possible<sup><a href="#ref1">1</a></sup>).</p>
+    <p>
+      The alternative to using argument dependent lookup in this situation is to provide a template specialization of std::swap for every type that requires a specialized swap. Although this is legal C++, no Boost libraries use this method, whereas many Boost libraries provide specialized swap functions in their own namespaces.
+    </p>
+    <p>
+      <tt>boost::swap</tt> also supports swapping built-in arrays. Note that <tt>std::swap</tt> doesn't yet do so, but a request to add an overload of <tt>std::swap</tt> for built-in arrays has been well-received by the Library Working Group of the C++ Standards Committee<sup><a href="#ref2">2</a></sup>.      
+    </p>
+    
+    <!-- Exception Safety -->
+    <h2>Exception Safety</h2>
+    <p>
+      <tt>boost::swap</tt> provides the same exception guarantee as the underlying swap function used, with one exception; for an array of type <tt>T[n]</tt>, where <tt>n > 1</tt> and the underlying swap function for <tt>T</tt> provides the strong exception guarantee, <tt>boost::swap</tt> provides only the basic exception guarantee.
+    </p>
+    
+    <!-- Requirements -->
+    <h2>Requirements</h2>
+    <p>Either:</p>
+    <ul>      
+      <li>T must be assignable</li>
+      <li>T must be copy constructible</li>
+    </ul>
+    <p>Or:</p>
+    <ul>
+      <li>A function with the signature <tt>swap(T&,T&)</tt> is available via argument dependent lookup</li>
+    </ul>
+    <p>Or:</p>
+    <ul>
+      <li>A template specialization of std::swap exists for T</li>
+    </ul>
+    <p>Or:</p>
+    <ul>
+      <li>T is a built-in array of swappable elements</li>
+    </ul>
+
+    
+    <!-- Portability -->
+    <h2>Portability</h2>
+    <p>
+      Several older compilers do not support argument dependent lookup <20> on these compilers <tt>boost::swap</tt> will call <tt>std::swap</tt>, ignoring any specialized swap functions that could be found as a result of argument dependent lookup.
+    </p>

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

+<h2><a name="rationale"></a>Rationale</h2>
+                  
+<p>Constructing and initializing objects in a generic way is difficult in
+    C++. The problem is that there are several different rules that apply
+for    initialization. Depending on the type, the value of a newly constructed
+  object  can be zero-initialized (logically 0), default-constructed (using
+  the default constructor), or indeterminate. When writing generic code,
+this  problem must be addressed. The template <code>value_initialized</code> provides
+a solution   with consistent syntax for value   initialization of scalar,
+union and class   types.
+Moreover, <code>value_initialized</code> offers a workaround to various
+compiler issues regarding value-initialization.
+
+Furthermore, a <code>const</code> object, <code>initialized_value</code> is provided,
+to avoid repeating the type name when retrieving the value from a
+<code>value_initialized&lt;T&gt;</code> object.
+<br>
+  </p>
+        
+<h2><a name="intro"></a>Introduction</h2>
+     
+<p>
+There are various ways to initialize a variable, in C++. The following
+declarations all <em>may</em> have a local variable initialized to its default
+value:
+<pre>
+  T1 var1;
+  T2 var2 = 0;
+  T3 var3 = {};
+  T4 var4 = T4();
+</pre> 
+Unfortunately, whether or not any of those declarations correctly
+initialize the variable very much depends on its type. The first
+declaration is valid for any <a href="http://www.sgi.com/tech/stl/DefaultConstructible.html">
+DefaultConstructible</a> type (by definition).
+However, it does not always do an initialization!
+It correctly initializes the variable when it's an instance of a
+class, and the author of the class has provided a proper default
+constructor. On the other hand, the value of <code>var1</code> is <em>indeterminate</em> when
+its type is an arithmetic type, like <code>int</code>, <code>float</code>, or <code>char</code>.
+An arithmetic variable
+is of course initialized properly by the second declaration, <code>T2
+var2 = 0</code>. But this initialization form usually won't work for a
+class type (unless the class was especially written to support being
+initialized that way). The third form,  <code>T3 var3 = {}</code>
+initializes an aggregate, typically a "C-style" <code>struct</code> or a "C-style" array.
+However, the syntax is not allowed for a class that has an explicitly declared
+constructor.  (But watch out for an upcoming C++ language change, 
+by Bjarne Stroustrup et al [<a href="#references">1</a>]!)
+The fourth form is the most generic form of them, as it
+can be used to initialize arithmetic types, class types, aggregates, pointers, and
+other types. The declaration,  <code>T4 var4 = T4()</code>, should be read
+as follows: First a temporary object is created, by <code>T4()</code>.
+This object is <a href="#valueinit">value-initialized</a>. Next the temporary
+object is copied to the named variable, <code>var4</code>. Afterwards, the temporary
+is destroyed. While the copying and the destruction are likely to
+be optimized away, C++ still requires the type <code>T4</code> to be
+<a href="CopyConstructible.html">CopyConstructible</a>.
+(So <code>T4</code> needs to be <em>both</em> DefaultConstructible <em>and</em> CopyConstructible.) 
+A class may not be CopyConstructible, for example because it may have a
+private and undefined copy constructor,
+or because it may be derived from <a href="utility.htm#Class_noncopyable">boost::noncopyable</a>.
+Scott Meyers [<a href="#references">2</a>] explains why a class would be defined like that.
+</p>
+<p>
+There is another, less obvious disadvantage to the fourth form, <code>T4 var4 = T4()</code>:
+It suffers from various  <a href="#compiler_issues">compiler issues</a>, causing
+a variable to be left uninitialized in some compiler specific cases.
+</p>
+<p>
+The template <a href="#val_init"><code>value_initialized</code></a>
+offers a generic way to initialize
+an object, like <code>T4 var4 = T4()</code>, but without requiring its type
+to be CopyConstructible. And it offers a workaround to those compiler issues
+regarding value-initialization as well! It allows getting an initialized
+variable of any type; it <em>only</em> requires the type to be DefaultConstructible.
+A properly <em>value-initialized</em> object of type <code>T</code> is
+constructed by the following declaration:
+<pre>
+  value_initialized&lt;T&gt; var;
+</pre>
+</p>
+<p>
+The <code>const</code> object <a href="#initialized_value"><code>initialized_value</code></a>
+allows value-initializing a variable as follows:
+<pre>
+  T var = initialized_value ;
+</pre>
+This form of initialization is semantically equivalent to <code>T4 var4 = T4()</code>,
+but robust against the aforementioned compiler issues.
+
+</p>
+
+<h2><a name="details"></a>Details</h2>
+<p>The C++ standard [<a href="#references">3</a>] contains the definitions 
+    of <code>zero-initialization</code> and <code>default-initialization</code>.
+     Informally, zero-initialization means that the object is given the initial
+     value 0 (converted to the type) and default-initialization means that
+ POD   [<a href="#references">4</a>] types are zero-initialized, while non-POD class
+ types   are initialized with their corresponding default constructors. A
+<i>declaration</i>   can contain an <i>initializer</i>, which specifies the
+object's initial value.  The initializer can be just '()', which states that
+the object shall be value-initialized  (but see below). However, if a <i>declaration</i> 
+  has no <i>initializer</i>  and it is of a non-<code>const</code>, non-<code>static</code> 
+   POD type, the initial value is indeterminate: <cite>(see &sect;8.5, [dcl.init], for the
+   accurate definitions).</cite></p>
+                   
+<pre>int x ; // no initializer. x value is indeterminate.<br>std::string s ; // no initializer, s is default-constructed.<br><br>int y = int() ; <br>// y is initialized using copy-initialization<br>// but the temporary uses an empty set of parentheses as the initializer,<br>// so it is default-constructed.<br>// A default constructed POD type is zero-initialized,<br>// therefore, y == 0.<br><br>void foo ( std::string ) ;<br>foo ( std::string() ) ; <br>// the temporary string is default constructed <br>// as indicated by the initializer ()  </pre>

+<h3><a name="valueinit">value-initialization</a></h3>
+                   
+<p>The first <a
+ href="http://anubis.dkuug.dk/JTC1/SC22/WG21/docs/cwg_defects.html">Technical 
+  Corrigendum for the C++ Standard</a> (TC1), whose draft   was released to
+  the public in November 2001, introduced <a
+ href="http://anubis.dkuug.dk/JTC1/SC22/WG21/docs/cwg_defects.html#178">Core 
+  Issue 178</a> (among   many other issues, of course).</p>
+                   
+<p> That issue introduced the new concept of <code>value-initialization</code>
+     (it also fixed the wording for zero-initialization). Informally, value-initialization 
+    is similar to default-initialization with the exception that in some cases
+    non-static data members and base class sub-objects are also value-initialized. 
+    The difference is that an object that is value-initialized won't have 
+(or    at least is less likely to have) indeterminate values for data members 
+ and   base class sub-objects; unlike the case of an object default constructed. 
+    (see Core Issue 178 for a normative description).</p>
+                   
+<p>In order to specify value-initialization of an object we need to use the
+     empty-set initializer: (). </p>
+                   
+<p>As before, a declaration with no intializer specifies default-initialization, 
+    and a declaration with a non-empty initializer specifies copy (=xxx) or
+  direct  (xxx) initialization. </p>
+                   
+<pre>template&lt;class T&gt; void eat(T);<br>int x ; // indeterminate initial value.<br>std::string s; // default-initialized.<br>eat ( int() ) ; // value-initialized<br>eat ( std::string() ) ; // value-initialized</pre>
+                    
+<h4><a name="valueinitsyn">value-initialization</a> syntax</h4>
+                   
+<p>Value initialization is specified using (). However, the empty set of
+parentheses is not permitted by the syntax of initializers because it is
+parsed as the declaration of a function taking no arguments: </p>
+                   
+<pre>int x() ; // declares function int(*)()</pre>
+                    
+<p>Thus, the empty () must be put in some other initialization context.</p>
+                   
+<p>One alternative is to use copy-initialization syntax:</p>
+                   
+<pre>int x = int() ;</pre>
+                    
+<p>This works perfectly fine for POD types. But for non-POD class types,
+copy-initialization searches for a suitable constructor, which could be,
+for instance, the copy-constructor (it also searches for a suitable conversion
+sequence but this doesn't apply in this context). For an arbitrary unknown
+type, using this syntax may not have the value-initialization effect intended
+because we don't know if a copy from a default constructed object is exactly
+the same as a default constructed object, and the compiler is allowed (in
+some cases), but never required to, optimize the copy away.</p>
+                   
+<p>One possible generic solution is to use value-initialization of a non static
+data member:</p>
+                   
+<pre>template&lt;class T&gt; <br>struct W <br>{<br>  // value-initialization of 'data' here.<br>  W() : data() {}<br>  T data ;<br>} ;<br>W&lt;int&gt; w ;<br>// w.data is value-initialized for any type. </pre>
+                    
+<p>This is the solution as it was supplied by earlier versions of the
+<code>value_initialized&lt;T&gt;</code> template
+     class. Unfortunately this approach suffered from various compiler issues.</p>
+		 
+<h4><a name="compiler_issues">compiler issues</a> </h4>
+
+Various compilers haven't yet fully implemented value-initialization.
+So when an object should be <em>value-initialized</em> (according to the C++ Standard),
+it <em>may</em> in practice still be left uninitialized, because of those
+compiler issues! It's hard to make a general statement on what those issues
+are like, because they depend on the compiler you are using, its version number,
+and the type of object you would like to have value-initialized.
+Compilers usually support value-initialization for built-in types properly.
+But objects of user-defined types that involve <em>aggregates</em> may <em>in some cases</em>
+be partially, or even entirely left uninitialized, when they should be value-initialized.
+</p>

+We have encountered issues regarding value-initialization on compilers by
+Microsoft, Sun, Borland, and GNU. Here is a list of bug reports on those issues:

+                    
+<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>

+                    
+<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

+                    
+<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

+                   
+<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>The obscure behavior of being able to modify a non-<code>const</code>
+wrapped object from within a constant wrapper can be avoided if access to
+the wrapped object is always performed with the <code>get()</code> idiom:</p>
+                   
+<pre>value_initialized&lt;int&gt; x ;<br>get(x) = 1 ; // OK<br><br>value_initialized&lt;int const&gt; cx ;<br>get(x) = 1 ; // ERROR: Cannot modify a const object<br><br>value_initialized&lt;int&gt; const x_c ;<br>get(x_c) = 1 ; // ERROR: Cannot modify a const object<br><br>value_initialized&lt;int const&gt; const cx_c ;<br>get(cx_c) = 1 ; // ERROR: Cannot modify a const object<br></pre>
+
+<h2><a name="initialized_value"><code>initialized_value</code></a></h2>
+
+<pre>
+namespace boost {
+class initialized_value_t
+{
+  public :
+    template &lt;class T&gt; operator T() const ;
+};
+
+initialized_value_t const initialized_value = {} ;
+
+} // namespace boost
+</pre>
+
+<code>initialized_value</code> provides a convenient way to get
+an initialized value: its conversion operator provides an appropriate
+<em>value-initialized</em> object for any CopyConstructible type.
+
+Suppose you need to have an initialized variable of type <code>T</code>.
+You could do it as follows:
+<pre>
+  T var = T();
+</pre>
+But as mentioned before, this form suffers from various compiler issues.
+The template <code>value_initialized</code> offers a workaround:
+<pre>
+  T var = get( value_initialized&lt;T&gt;() );
+</pre>
+Unfortunately both forms repeat the type name, which
+is rather short now (<code>T</code>), but could of course be 
+more like <code>Namespace::Template&lt;Arg&gt;::Type</code>.
+Instead, one could use <code>initialized_value</code> as follows:
+<pre>
+  T var = initialized_value ;
+</pre>
+                    
+<h3><a name="references">References</a></h3>
+          [1] Bjarne Stroustrup, Gabriel Dos Reis, and J. Stephen Adamczyk wrote
+          various papers, proposing to extend the support for brace-enclosed <em>initializer lists</em>
+          in the next version of C++.
+          This would allow a variable <code>var</code> of any DefaultConstructible type
+          <code>T</code> to be <em>value-initialized</em> by doing <code>T var = {}</code>.
+          The papers are listed at Bjarne's web page,
