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

-<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>

-
-<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>If the appropriate features of C++2011 are present, there will be a single
-constructor template.  It implements &quot;perfect forwarding&quot; to the best
-constructor call of <code>member</code> (if any).  The constructor template is
-marked both <code>constexpr</code> and <code>explicit</code>.  The former will
-be ignored if the corresponding inner constructor call (of <code>member</code>)
-does not have the marker.  The latter binds the other way; always taking
-effect, even when the inner constructor call does not have the marker.  The
-constructor template propagates the <code>noexcept</code> status of the inner
-constructor call.  (The constructor template has a trailing parameter with a
-default value that disables the template when its signature is too close to the
-signatures of the automatically-defined non-template copy- and/or
-move-constructors of <code>base_from_member</code>.)</p>
-
-<p>On earlier-standard compilers, there is a default constructor and several
-constructor member templates.  These constructor templates can take as many
-arguments (currently up to ten) as possible and pass them to a constructor of
-the data member.</p>
-
-<p>Since C++ does not allow any way to explicitly state
-the template parameters of a templated constructor, make sure that
-the arguments are already close as possible to the actual type used in
-the data member's desired constructor.  Explicit conversions may be
-necessary.</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.)  This constant is ignored when C++2011 features are present.</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>

-</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++ (except <code>nullptr</code> from
-C++2011) 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.  (If C++2011's <code>nullptr</code> is
-used, it still needs a conversion if multiple pointer types can be accepted in
-a constructor call but <code>std::nullptr_t</code> cannot.)</p>

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

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

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

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

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

-      The role of the function template declval() is a transformation of a type T

-      an lvalue if and only if T is an lvalue-reference, otherwise an rvalue. To

-      The provision of a new library component that allows the production of values
-      in unevaluated expressions is considered important to realize constrained templates
-      in C++0x where concepts are not available. This extremely light-weight function
-      is expected to be part of the daily tool-box of the C++0x programmer.

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

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

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

-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 were 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>

-<!--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; }

-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>
-With respect to function templates, <TT>enable_if</TT> can be used in multiple different ways:
-
-<UL>
-<LI>As the return type of an instantiatied function
-<LI>As an extra parameter of an instantiated function
-<LI>As an extra template parameter (useful only in a compiler that supports C++0x default
-arguments for function template parameters, see <A href="#sec:enable_if_0x">Enabling function
-templates in C++0x</a> for details)
-</UL>
-
-In the previous section, the return type form of <TT>enable_if</TT> was shown. As an example
-of using the form of <TT>enable_if</TT> that works via an extra function parameter, 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>
-Which way to write the enabler is largely a matter of taste, but for certain functions, only a
-subset of the options is possible:
-<UL><LI>
-Many operators have a fixed number of arguments, thus <TT>enable_if</TT> must be used either in the
-return type or in an extra template parameter.
-<LI>Functions that have a variadic parameter list must use either the return type form or an extra
-template parameter.
-<LI>Constructors do not have a return type so you must use either an extra function parameter or an
-extra template parameter.
-<LI>Constructors that have a variadic parameter list must an extra template parameter.
-<LI>Conversion operators can only be written with an extra template parameter.

-In a compiler which supports C++0x default arguments for function template parameters, you can
-enable and disable function templates by adding an additional template parameter. This approach
-works in all situations where you would use either the return type form of <TT>enable_if</TT> or
-the function parameter form, including operators, constructors, variadic function templates, and

-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;

-match the primary template.
-The condition can be any compile-time boolean expression that depends on the

-
-<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>

-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

-<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

-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;

-
-  <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>

-
-  <h3>Members</h3>
-
-  <p>The generator iterator implements the member functions and operators

-  <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>

-  <h3>Example</h3>
-
-  <p>The following program shows how <code>generator_iterator</code>
-  transforms a generator into an input iterator.</p>

+The [macroref BOOST_IDENTITY_TYPE] macro expands to an expression that evaluates (at compile-time) to the specified type.
 The specified type is never split into multiple macro parameters because it is always wrapped by a set of extra round parenthesis `()`.
 In fact, a total of two sets of round parenthesis must be used: The parenthesis to invoke the macro `BOOST_IDENTITY_TYPE(...)` plus the inner parenthesis to wrap the type passed to the macro `BOOST_IDENTITY_TYPE((...))`.

+//            correct named return value optimization (NRVO) to produce optimal
+//            code.  (Daniel Frey)
+//  02 Dec 01 Bug fixed in random_access_iteratable.  (Helmut Zeisel)
+//  28 Sep 01 Factored out iterator operator groups.  (Daryle Walker)
+//  27 Aug 01 'left' form for non commutative operators added;
+//            additional classes for groups of related operators added;
+//            workaround for empty base class optimization
+//            bug of GCC 3.0 (Helmut Zeisel)
+//  25 Jun 01 output_iterator_helper changes: removed default template 
+//            parameters, added support for self-proxying, additional 
+//            documentation and tests (Aleksey Gurtovoy)
+//  29 May 01 Added operator classes for << and >>.  Added input and output
+//            iterator helper classes.  Added classes to connect equality and
+//            relational operators.  Added classes for groups of related
+//            operators.  Reimplemented example operator and iterator helper
+//            classes in terms of the new groups.  (Daryle Walker, with help
+//            from Alexy Gurtovoy)
+//  11 Feb 01 Fixed bugs in the iterator helpers which prevented explicitly
+//            supplied arguments from actually being used (Dave Abrahams)
+//  04 Jul 00 Fixed NO_OPERATORS_IN_NAMESPACE bugs, major cleanup and
+//            refactoring of compiler workarounds, additional documentation
+//            (Alexy Gurtovoy and Mark Rodgers with some help and prompting from
+//            Dave Abrahams) 
+//  28 Jun 00 General cleanup and integration of bugfixes from Mark Rodgers and
+//            Jeremy Siek (Dave Abrahams)
+//  20 Jun 00 Changes to accommodate Borland C++Builder 4 and Borland C++ 5.5
+//            (Mark Rodgers)
+//  20 Jun 00 Minor fixes to the prior revision (Aleksey Gurtovoy)
+//  10 Jun 00 Support for the base class chaining technique was added
+//            (Aleksey Gurtovoy). See documentation and the comments below 
+//            for the details. 
+//  12 Dec 99 Initial version with iterator operators (Jeremy Siek)
+//  18 Nov 99 Change name "divideable" to "dividable", remove unnecessary
+//            specializations of dividable, subtractable, modable (Ed Brey) 
+//  17 Nov 99 Add comments (Beman Dawes)
+//            Remove unnecessary specialization of operators<> (Ed Brey)
+//  15 Nov 99 Fix less_than_comparable<T,U> second operand type for first two
+//            operators.(Beman Dawes)
+//  12 Nov 99 Add operators templates (Ed Brey)
+//  11 Nov 99 Add single template parameter version for compilers without
+//            partial specialization (Beman Dawes)
+//  10 Nov 99 Initial version
+
+// 10 Jun 00:
+// An additional optional template parameter was added to most of 
+// operator templates to support the base class chaining technique (see 
+// documentation for the details). Unfortunately, a straightforward
+// implementation of this change would have broken compatibility with the
+// previous version of the library by making it impossible to use the same
+// template name (e.g. 'addable') for both the 1- and 2-argument versions of
+// an operator template. This implementation solves the backward-compatibility
+// issue at the cost of some simplicity.
+//
+// One of the complications is an existence of special auxiliary class template
+// 'is_chained_base<>' (see 'detail' namespace below), which is used
+// to determine whether its template parameter is a library's operator template
+// or not. You have to specialize 'is_chained_base<>' for each new 
+// operator template you add to the library.
+//
+// However, most of the non-trivial implementation details are hidden behind 
+// several local macros defined below, and as soon as you understand them,
+// you understand the whole library implementation.

-//~ 1 The library provides the function template declval to simplify the definition of expressions which occur as

-//~ 2 Remarks: If this function is used, the program is ill-formed.
-//~ 3 Remarks: The template parameter T of declval may be an incomplete type.
-//~ [ Example:
-
-//~ template <class To, class From>
-//~ decltype(static_cast<To>(declval<From>())) convert(From&&);
-
-//~ declares a function template convert which only participats in overloading if the type From can be

-<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.

-
-<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,

-
-    <h1>Swap</h1>
-    
-    <p>
-      <tt>template&lt;class T&gt; void swap(T&amp; <em>left</em>, T&amp; <em>right</em>);</tt>
-    </p>
-     
-    <!-- Introduction -->
-    <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 <tt>std::swap</tt> 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> originally did not do so, but a request to add an overload of <tt>std::swap</tt> for built-in arrays has been accepted by 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&amp;,T&amp;)</tt> is available via argument dependent lookup</li>
-    </ul>
-    <p>Or:</p>
-    <ul>
-      <li>A template specialization of <tt>std::swap</tt> 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 &#x2012; 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.
