+
+<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.  Ron 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.</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>
+template &lt; typename MemberType, int UniqueID = 0 &gt;
+class boost::base_from_member
+{
+protected:
+    MemberType  member;
+
+    explicit  base_from_member();
+
+    template&lt; typename T1 &gt;
+    explicit  base_from_member( T1 x1 );
+
+    //...
+
+    template&lt; typename T1, typename T2, typename T3 &gt;
+    explicit  base_from_member( T1 x1, T2 x2, T3 x3 );
+};
+</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 three) 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>
+
+<h2><a name="usage">Usage</a></h2>
+
+<p>With the starting example, the <code>fdoutbuf</code> sub-object needs
+to be encapsulated in a base class that is inheirited before
+<code>std::ostream</code>.</p>
+
+<blockquote><pre>
+#include &lt;boost/utility/base_from_member.hpp&gt;
+
+#include &lt;streambuf&gt;  <i>// for std::streambuf</i>
+#include &lt;ostream&gt;    <i>// for std::ostream</i>
+
+class fdoutbuf
+    : public std::streambuf
+{
+public:
+    explicit fdoutbuf( int fd );
+    //...
+};
+
+class fdostream
+    : private boost::base_from_member&lt;fdoutbuf&gt;
+    , public std::ostream
+{
+    // Helper typedef's
+    typedef boost::base_from_member&lt;fdoutbuf&gt;  pbase_type;
+    typedef std::ostream                        base_type;
+
+public:
+    explicit fdostream( int fd )
+        : pbase_type( fd ), base_type( &amp;member )
+        {}
+    //...
+};
+</pre></blockquote>
+
+<p>The base-from-member idiom is an implementation detail, so it
+should not be visible to the clients (or any derived classes) of
+<code>fdostream</code>.  Due to the initialization order, the
+<code>fdoutbuf</code> sub-object will get initialized before the
+<code>std::ostream</code> sub-object does, making the former
+sub-object safe to use in the latter sub-object's construction.  Since the
+<code>fdoutbuf</code> sub-object of the final type is the only sub-object
+with the name &quot;member,&quot; that name can be used
+unqualified within the final class.</p>
+
+<h2><a name="example">Example</a></h2>
+
+<p>The base-from-member class templates should commonly involve
+only one base-from-member sub-object, usually for attaching a
+stream-buffer to an I/O stream.  The next example demonstrates how
+to use multiple base-from-member sub-objects and the resulting
+qualification issues.</p>
+
+<blockquote><pre>
+#include &lt;boost/utility/base_from_member.hpp&gt;
+
+#include &lt;cstddef&gt;  <i>// for NULL</i>
+
+struct an_int
+{
+    int  y;
+
+    an_int( float yf );
+};
+
+class switcher
+{
+public:
+    switcher();
+    switcher( double, int * );
+    //...
+};
+
+class flow_regulator
+{
+public:
+    flow_regulator( switcher &amp;, switcher &amp; );
+    //...
+};
+
+template &lt; unsigned Size &gt;
+class fan
+{
+public:
+    explicit fan( switcher );
+    //...
+};
+
+class system
+    : private boost::base_from_member&lt;an_int&gt;
+    , private boost::base_from_member&lt;switcher&gt;
+    , private boost::base_from_member&lt;switcher, 1&gt;
+    , private boost::base_from_member&lt;switcher, 2&gt;
+    , protected flow_regulator
+    , public fan&lt;6&gt;
+{
+    // Helper typedef's
+    typedef boost::base_from_member&lt;an_int&gt;       pbase0_type;
+    typedef boost::base_from_member&lt;switcher&gt;     pbase1_type;
+    typedef boost::base_from_member&lt;switcher, 1&gt;  pbase2_type;
+    typedef boost::base_from_member&lt;switcher, 2&gt;  pbase3_type;
+
+    typedef flow_regulator  base1_type;
+    typedef fan&lt;6&gt;          base2_type;
+
+public:
+    system( double x );
+    //...
+};
+
+system::system( double x )
+    : pbase0_type( 0.2 )
+    , pbase1_type()
+    , pbase2_type( -16, &amp;this-&gt;pbase0_type::member )
+    , pbase3_type( x, static_cast&lt;int *&gt;(NULL) )
+    , base1_type( pbase3_type::member, pbase1_type::member )
+    , base2_type( pbase2_type::member )
+{
+    //...
+}
+</pre></blockquote>
+
+<p>The final class has multiple sub-objects with the name
+&quot;member,&quot; so any use of that name needs qualification by
+a name of the appropriate base type.  (Using <code>typedef</code>s
+ease mentioning the base types.)  However, the fix introduces a new
+problem when a pointer is needed.  Using the address operator with
+a sub-object qualified with its class's name results in a pointer-to-member
+(here, having a type of <code>an_int boost::base_from_member&lt;an_int,
+0&gt; :: *</code>) instead of a pointer to the member (having a type of
+<code>an_int *</code>).  The new problem is fixed by qualifying the
+sub-object with &quot;<code>this-&gt;</code>,&quot; and is needed just
+for pointers, and not for references or values.</p>
+
+<p>There are some argument conversions in the initialization.  The
+constructor argument for <code>pbase0_type</code> is converted from
+<code>double</code> to <code>float</code>.  The first constructor
+argument for <code>pbase2_type</code> is converted from <code>int</code>
+to <code>double</code>.  The second constructor argument for
+<code>pbase3_type</code> is a special case of necessary conversion; all
+forms of the null-pointer literal in C++ also look like compile-time
+integral expressions, so C++ always interprets such code as an integer
+when it has overloads that can take either an integer or a pointer.  The
+last conversion is necessary for the compiler to call a constructor form
+with the exact pointer type used in <code>switcher</code>'s constructor.</p>

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

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

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

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

-compressed_pair behaves just like std::pair.</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 &quot;do
+nothing&quot; assignment operator defined. This is due to a bug
+in the way VC6 generates implicit assignment operators.</p>

+<h1>Counting Iterator Adaptor</h1>
+
+Defined in header
+<a href="../../boost/counting_iterator.hpp">boost/counting_iterator.hpp</a>
+
+<p>
+How would you fill up a vector with the numbers zero
+through one hundred using <a
+href="http://www.sgi.com/tech/stl/copy.html"><tt>std::copy()</tt></a>? The
+only iterator operation missing from builtin integer types is an
+<tt>operator*()</tt> that returns the current
+value of the integer.  The counting iterator adaptor adds this crucial piece of
+functionality to whatever type it wraps. One can use the
+counting iterator adaptor not only with integer types, but with any
+type that is <tt>Incrementable</tt> (see type requirements <a href="#requirements">below</a>).  The
+following <b>pseudo-code</b> shows the general idea of how the
+counting iterator is implemented.
+</p>
+
+<pre>
+  // inside a hypothetical counting_iterator class...
+  typedef Incrementable value_type;
+  value_type counting_iterator::operator*() const {
+    return this->base; // no dereference!
+  }
+</pre>
+
+All of the other operators of the counting iterator behave in the same
+fashion as the <tt>Incrementable</tt> base type.

+<h2><a name="counting_iterator_generator">The Counting Iterator Type
+Generator</a></h2>
+
+The class template <tt>counting_iterator_generator&lt;Incrementable&gt;</tt> is a <a href="../../more/generic_programming.html#type_generator">type generator</a> for counting iterators.
+
+<pre>
+template &lt;class Incrementable&gt;
+class counting_iterator_generator
+{
+public:
+    typedef <a href="./iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt;...&gt; type;
+};
+</pre>
+
+<h3>Example</h3>
+
+In this example we use the counting iterator generator to create a
+counting iterator, and count from zero to four.
+
+<pre>
+#include &lt;boost/config.hpp&gt;
+#include &lt;iostream&gt;
+#include &lt;boost/counting_iterator.hpp&gt;
+
+int main(int, char*[])
+{
+  // Example of using counting_iterator_generator
+  std::cout &lt;&lt; "counting from 0 to 4:" &lt;&lt; std::endl;
+  boost::counting_iterator_generator&lt;int&gt;::type first(0), last(4);
+  std::copy(first, last, std::ostream_iterator&lt;int&gt;(std::cout, " "));
+  std::cout &lt;&lt; std::endl;
+
+  // to be continued...
+</pre>
+The output from this part is:
+<pre>
+counting from 0 to 4:
+0 1 2 3 
+</pre>
+
+<h3>Template Parameters</h3>
+
+<Table border>
+<TR>
+<TH>Parameter</TH><TH>Description</TH>
+</TR>
+
+<TR>
+<TD><tt>Incrementable</tt></TD>
+<TD>The type being wrapped by the adaptor.</TD>
+</TR>
+
+</Table>
+
+<h3>Model of</h3>
+
+If the <tt>Incrementable</tt> type has all of the functionality of a
+<a href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
+Access Iterator</a> except the <tt>operator*()</tt>, then the counting
+iterator will be a model of <a
+href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
+Access Iterator</a>. If the <tt>Incrementable</tt> type has less
+functionality, then the counting iterator will have correspondingly
+less functionality.
+
+<h3><a name="requirements">Type Requirements</a></h3>
+
+The <tt>Incrementable</tt> type must be <a
+href="http://www.sgi.com/tech/stl/DefaultConstructible.html">Default
+Constructible</a>, <a href="./CopyConstructible.html">Copy
+Constructible</a>, and <a href="./Assignable.html">Assignable</a>.
+Also, the <tt>Incrementable</tt> type must provide access to an
+associated <tt>difference_type</tt> and <tt>iterator_category</tt>
+through the <a
+href="#counting_iterator_traits"><tt>counting_iterator_traits</tt></a>
+class.
+
+<p>
+Furthermore, if you wish to create a counting iterator that is a <a
+href="http://www.sgi.com/tech/stl/ForwardIterator.html"> Forward
+Iterator</a>, then the following expressions must be valid:
+<pre>
+Incrementable i, j;
++i         // pre-increment
+i == j      // operator equal
+</pre>
+If you wish to create a counting iterator that is a <a
+href="http://www.sgi.com/tech/stl/BidirectionalIterator.html">
+Bidirectional Iterator</a>, then pre-decrement is also required:
+<pre>
+--i
+</pre>
+If you wish to create a counting iterator that is a <a
+href="http://www.sgi.com/tech/stl/RandomAccessIterator.html"> Random
+Access Iterator</a>, then these additional expressions are also required:
+<pre>
+<a href="#counting_iterator_traits">counting_iterator_traits</a>&lt;Incrementable&gt;::difference_type n;
+i += n
+n = i - j
+i < j
+</pre>
+
+
+
+<h3>Members</h3>
+
+The counting 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. In addition it has the following
+constructor:
+
+<pre>
+counting_iterator_generator::type(const Incrementable&amp; i)
+</pre>
+
+<p>
+<hr>
+<p>
+
+
+<h2><a name="make_counting_iterator">The Counting Iterator Object Generator</a></h2>
+
+<pre>
+template &lt;class Incrementable&gt;
+typename counting_iterator_generator&lt;Incrementable&gt;::type
+make_counting_iterator(Incrementable base);
+</pre>
+
+An <a href="../../more/generic_programming.html#object_generator">object
+generator</a> function that provides a convenient way to create counting
+iterators.<p>
+
+
+
+<h3>Example</h3>
+
+In this example we count from negative five to positive five, this
+time using the <tt>make_counting_iterator()</tt> function to save some
+typing.
+
+<pre>
+  // continuing from previous example...
+
+  std::cout &lt;&lt; "counting from -5 to 4:" &lt;&lt; std::endl;
+  std::copy(boost::make_counting_iterator(-5),
+	    boost::make_counting_iterator(5),
+	    std::ostream_iterator&lt;int&gt;(std::cout, " "));
+  std::cout &lt;&lt; std::endl;
+
+  // to be continued...
+</pre>
+The output from this part is:
+<pre>
+counting from -5 to 4:
+-5 -4 -3 -2 -1 0 1 2 3 4 
+</pre>
+
+In the next example we create an array of numbers, and then create a
+second array of pointers, where each pointer is the address of a
+number in the first array. The counting iterator makes it easy to do
+this since dereferencing a counting iterator that is wrapping an
+iterator over the array of numbers just returns a pointer to the
+current location in the array. We then use the <a
+href="./indirect_iterator.htm">indirect iterator adaptor</a> to print
+out the number in the array by accessing the numbers through the array
+of pointers.
+
+<pre>
+  // continuing from previous example...
+
+  const int N = 7;
+  std::vector&lt;int&gt; numbers;
+  // Fill "numbers" array with [0,N)
+  std::copy(boost::make_counting_iterator(0), boost::make_counting_iterator(N),
+	    std::back_inserter(numbers));
+
+  std::vector&lt;std::vector&lt;int&gt;::iterator&gt; pointers;
+
+  // Use counting iterator to fill in the array of pointers.
+  std::copy(boost::make_counting_iterator(numbers.begin()),
+	    boost::make_counting_iterator(numbers.end()),
+	    std::back_inserter(pointers));
+
+  // Use indirect iterator to print out numbers by accessing
+  // them through the array of pointers.
+  std::cout &lt;&lt; "indirectly printing out the numbers from 0 to " 
+	    &lt;&lt; N &lt;&lt; std::endl;
+  std::copy(boost::make_indirect_iterator(pointers.begin()),
+	    boost::make_indirect_iterator(pointers.end()),
+	    std::ostream_iterator&lt;int&gt;(std::cout, " "));
+  std::cout &lt;&lt; std::endl;
+</pre>
+The output is:
+<pre>
+indirectly printing out the numbers from 0 to 7
+0 1 2 3 4 5 6 
+</pre>
+

+
+<h2><a name="counting_iterator_traits">Counting Iterator Traits</a></h2>
+
+The counting iterator adaptor needs to determine the appropriate
+<tt>difference_type</tt> and <tt>iterator_category</tt> to use based on the
+<tt>Incrementable</tt> type supplied by the user.  The
+<tt>counting_iterator_traits</tt> class provides these types.  If the
+<tt>Incrementable</tt> type is an integral type or an iterator, these types
+will be correctly deduced by the <tt>counting_iterator_traits</tt> provided by
+the library. Otherwise, the user must specialize
+<tt>counting_iterator_traits</tt> for her type or add nested typedefs to
+her type to fulfill the needs of
+<a href="http://www.sgi.com/tech/stl/iterator_traits.html">
+<tt>std::iterator_traits</tt></a>.
+
+<p>The following pseudocode describes how the <tt>counting_iterator_traits</tt> are determined:
+
+<pre>
+template &lt;class Incrementable&gt;
+struct counting_iterator_traits
+{
+  if (numeric_limits&lt;Incrementable&gt::is_specialized) {
+    if (!numeric_limits&lt;Incrementable&gt::is_integer)
+       COMPILE_TIME_ERROR;
+
+    if (!numeric_limits&lt;Incrementable&gt::is_bounded
+        &amp;&amp; numeric_limits&lt;Incrementable&gt;::is_signed) {
+        typedef Incrementable difference_type;
+    }
+    else if (numeric_limits&lt;Incrementable&gt::is_integral) {
+        typedef <i>next-larger-signed-type-or-intmax_t</i> difference_type;
+    }
+    typedef std::random_access_iterator_tag iterator_category;   
+  } else {
+    typedef std::iterator_traits&lt;Incrementable&gt;::difference_type difference_type;
+    typedef std::iterator_traits&lt;Incrementable&gt;::iterator_category iterator_category;
+  }
+};
+</pre>
+
+<p>The italicized sections above are implementation details, but it is important
+to know that the <tt>difference_type</tt> for integral types is selected so that
+it can always represent the difference between two values if such a built-in
+integer exists. On platforms with a working <tt>std::numeric_limits</tt>
+implementation, the <tt>difference_type</tt> for any variable-length signed
+integer type <tt>T</tt> is <tt>T</tt> itself.

+<h1>Filter Iterator Adaptor</h1>
+
+Defined in header
+<a href="../../boost/iterator_adaptors.hpp">boost/iterator_adaptors.hpp</a>
+
+
+<p>
+The filter iterator adaptor creates a view of an iterator range in
+which some elements of the range are skipped over. A <a
+href="http://www.sgi.com/tech/stl/Predicate.html">Predicate</a>
+function object controls which elements are skipped. When the
+predicate is applied to an element, if it returns <tt>true</tt> then
+the element is retained and if it returns <tt>false</tt> then the
+element is skipped over.
+
+
+<h2>Synopsis</h2>
+
+<pre>
+namespace boost {
+  template &lt;class Predicate, class BaseIterator, ...&gt;
+  class filter_iterator_generator;
+
+  template &lt;class Predicate, class BaseIterator&gt;

+<h2><a name="filter_iterator_generator">The Filter Iterator Type
+Generator</a></h2>
+
+The class <tt>filter_iterator_generator</tt> is a helper class whose
+purpose is to construct a filter iterator type.  The template
+parameters for this class are the <tt>Predicate</tt> function object
+type and the <tt>BaseIterator</tt> type that is being wrapped.  In
+most cases the associated types for the wrapped iterator can be
+deduced from <tt>std::iterator_traits</tt>, but in some situations the
+user may want to override these types, so there are also template
+parameters for each of the iterator's associated types.
+
+<pre>
+template &lt;class Predicate, class BaseIterator,
+          class Value, class Reference, class Pointer, class Category, class Distance>
+class filter_iterator_generator
+{
+public:
+  typedef <tt><a href="./iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt...&gt;</tt> type; // the resulting filter iterator type 
+}
+</pre>
+
+
+<h3>Example</h3>
+
+The following example uses filter iterator to print out all the
+positive integers in an array. 
+
+<pre>
+struct is_positive_number {
+  bool operator()(int x) { return 0 &lt; x; }
+};
+int main() {
+  int numbers[] = { 0, -1, 4, -3, 5, 8, -2 };
+  const int N = sizeof(numbers)/sizeof(int);
+
+  typedef boost::filter_iterator_generator&lt;is_positive_number, int*, int&gt;::type FilterIter;
+  is_positive_number predicate;
+  FilterIter::policies_type policies(predicate, numbers + N);
+  FilterIter filter_iter_first(numbers, policies);
+  FilterIter filter_iter_last(numbers + N, policies);
+
+  std::copy(filter_iter_first, filter_iter_last, std::ostream_iterator&lt;int&gt;(std::cout, " "));
+  std::cout &lt;&lt; std::endl;
+  return 0;
+}
+</pre>
+The output is:
+<pre>
+4 5 8

+<h3>Model of</h3>
+
+The filter iterator adaptor (the type
+<tt>filter_iterator_generator<...>::type</tt>) may be a model of <a
+href="http://www.sgi.com/tech/stl/InputIterator.html">InputIterator</a> or <a
+href="http://www.sgi.com/tech/stl/ForwardIterator.html">ForwardIterator</a>
+depending on the adapted iterator type.
+
+
+<h3>Members</h3>
+
+The filter iterator type implements all of the member functions and
+operators required of the <a
+href="http://www.sgi.com/tech/stl/ForwardIterator.html">ForwardIterator</a>
+concept.  In addition it has the following constructor:
+
+<pre>filter_iterator_generator::type(const BaseIterator& it, const Policies& p = Policies())</pre>
+
+<p>
+The policies type has only one public function, which is its constructor:
+
+<pre>filter_iterator_generator::policies_type(const Predicate& p, const BaseIterator& end)</pre>

+<pre>
+template &lt;class Predicate, class BaseIterator&gt;
+typename filter_generator&lt;Predicate, BaseIterator&gt;::type
+make_filter_iterator(BaseIterator first, BaseIterator last, const Predicate& p = Predicate())
+</pre>
+
+This function provides a convenient way to create filter iterators.
+
+<h3>Example</h3>
+
+In this example we print out all numbers in the array that are
+greater than negative two.
+
+<pre>
+int main()
+{
+  int numbers[] = { 0, -1, 4, -3, 5, 8, -2 };
+  const int N = sizeof(numbers)/sizeof(int);
+
+  std::copy(boost::make_filter_iterator(numbers, numbers + N, 
+					std::bind2nd(std::greater<int>(), -2)),
+	    boost::make_filter_iterator(numbers + N, numbers + N, 
+					std::bind2nd(std::greater<int>(), -2)),
+	    std::ostream_iterator<int>(std::cout, " "));
+  std::cout << std::endl;
+
+}
+</pre>
+The output is:
+<pre>
+0 -1 4 5 8 
+</pre>
+
+<p>
+In the next example we print the positive numbers using the
+<tt>make_filter_iterator()</tt> function.
+
+<pre>
+struct is_positive_number {
+  bool operator()(int x) { return 0 &lt; x; }
+};
+int main()
+{
+  int numbers[] = { 0, -1, 4, -3, 5, 8, -2 };
+  const int N = sizeof(numbers)/sizeof(int);
+
+  std::copy(boost::make_filter_iterator&lt;is_positive_number&gt;(numbers, numbers + N),
+	    boost::make_filter_iterator&lt;is_positive_number&gt;(numbers + N, numbers + N),
+	    std::ostream_iterator&lt;int&gt;(std::cout, " "));
+  std::cout &lt;&lt; std::endl;
+  return 0;
+}
+</pre>
+The output is:
+<pre>
+4 5 8
+</pre>
+
+
+<h3>Notes</h3>
+
+<a name="1">[1]</a> If the compiler does not support partial
+specialization and the wrapped iterator type is a builtin pointer then
+the <tt>Value</tt> type must be explicitly specified (don't use the
+default).

+    <h1>Function Output Iterator Adaptor</h1>
+    Defined in header <a href=
+    "../../boost/function_output_iterator.hpp">boost/function_output_iterator.hpp</a> 
+
+    <p>The function output iterator adaptor makes it easier to create
+    custom output iterators. The adaptor takes a <a
+    href="http://www.sgi.com/tech/stl/UnaryFunction.html">Unary
+    Function</a> and creates a model of <a
+    href="http://www.sgi.com/tech/stl/OutputIterator.html">Output
+    Iterator</a>. Each item assigned to the output iterator is passed
+    as an argument to the unary function.  The motivation for this
+    iterator is that creating a C++ Standard conforming output
+    iterator is non-trivial, particularly because the proper
+    implementation usually requires a proxy object. On the other hand,
+    creating a function (or function object) is much simpler.

+<h1>Generator Iterator Adaptor</h1>
+Defined in header <a href="../../boost/generator_iterator.hpp">boost/generator_iterator.hpp</a> 
+<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.
+
+<h2>Synopsis</h2>

+<h2>The Generator Iterator Generator Class</h2>
+
+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.
+
+<pre>
+template &lt;class Generator>
+class generator_iterator_generator
+{
+public:
+  typedef <a href="iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt...&gt; type; // the resulting generator iterator type 
+}
+</pre>
+

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

+
+The <tt>make_generator_iterator()</tt> function provides a

+saves the user the trouble of explicitly writing out the iterator
+types.

+
+
+<h3>Example</h3>
+
+The following program shows how <code>generator_iterator</code>
+transforms a generator into an input iterator.
+
+<blockquote>
+<pre>
+#include &lt;iostream>
+#include &lt;boost/generator_iterator.hpp>
+
+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;

 //  Revision History
+//  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

+    Defined in header <a href=
+    "../../boost/iterator_adaptors.hpp">boost/iterator_adaptors.hpp</a> 
+
+    <p>The indirect iterator adaptor augments an iterator by applying an
+    <b>extra</b> dereference inside of <tt>operator*()</tt>. For example, this
+    iterator makes it possible to view a container of pointers or
+    smart-pointers (e.g. <tt>std::list&lt;boost::shared_ptr&lt;foo&gt;
+    &gt;</tt>) as if it were a container of the pointed-to type. The following
+    <b>pseudo-code</b> shows the basic idea of the indirect iterator:
+
+    <blockquote>
+<pre>
+// inside a hypothetical indirect_iterator class...
+typedef std::iterator_traits&lt;BaseIterator&gt;::value_type Pointer;
+typedef std::iterator_traits&lt;Pointer&gt;::reference reference;
+
+reference indirect_iterator::operator*() const {
+  return **this-&gt;base_iterator;
+}
+</pre>
+    </blockquote>
+
+    <h2>Synopsis</h2>
+
+    <blockquote>
+<pre>
+namespace boost {
+  template &lt;class BaseIterator,
+            class Value, class Reference, class Category, class Pointer&gt;

+
+    <h2><a name="indirect_iterator_generator">The Indirect Iterator Type
+    Generator</a></h2>
+    The <tt>indirect_iterator_generator</tt> template is a <a href=
+    "../../more/generic_programming.html#type_generator">generator</a> of
+    indirect iterator types. The main template parameter for this class is the
+    <tt>BaseIterator</tt> type that is being wrapped. In most cases the type of
+    the elements being pointed to can be deduced using
+    <tt>std::iterator_traits</tt>, but in some situations the user may want to
+    override this type, so there are also template parameters that allow a user
+    to control the <tt>value_type</tt>, <tt>pointer</tt>, and
+    <tt>reference</tt> types of the resulting iterators. 
+
+    <blockquote>
+<pre>
+template &lt;class BaseIterator,
+          class Value, class Reference, class Pointer&gt;
+class indirect_iterator_generator
+{
+public:
+  typedef <tt><a href=
+"./iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt;...&gt;</tt> type; // the resulting indirect iterator type 
+};
+</pre>
+    </blockquote>
+
+    <h3>Example</h3>
+    This example uses the <tt>indirect_iterator_generator</tt> to create

+    <h3>Concept Model</h3>
+    The indirect iterator will model whichever <a href=
+    "http://www.sgi.com/tech/stl/Iterators.html">standard iterator
+    concept category</a> is modeled by the base iterator. Thus, if the
+    base iterator is a model of <a href=
+    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
+    Access Iterator</a> then so is the resulting indirect iterator. If
+    the base iterator models a more restrictive concept, the resulting
+    indirect iterator will model the same concept <a href="#3">[3]</a>.
+
+    <h3>Members</h3>
+    The indirect 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. In addition it has the following constructor: 
+<pre>
+explicit indirect_iterator_generator::type(const BaseIterator&amp; it)

+    <h3>Concept Model</h3>
+
+    The indirect iterators will model whichever <a href=

+    concept category</a> is modeled by the base iterator. Thus, if the

+    Access Iterator</a> then so are the resulting indirect

+
+
+    <h3>Members</h3>
+    The resulting <tt>iterator</tt> and <tt>const_iterator</tt> types implement
+    the member functions and operators required of the <a href=
+    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access
+    Iterator</a> concept. In addition they support the following constructors: 
+

+<pre>

+
+    <p>
+
+    <h2><a name="make_indirect_iterator">The Indirect Iterator Object
+    Generator</a></h2>
+    The <tt>make_indirect_iterator()</tt> function provides a more convenient
+    way to create indirect iterator objects. The function saves the user the
+    trouble of explicitly writing out the iterator types. 
+
+    <blockquote>
+<pre>
+template &lt;class BaseIterator&gt;
+typename indirect_iterator_generator&lt;BaseIterator&gt;::type
+make_indirect_iterator(BaseIterator base)

+    </blockquote>
+
+    <h3>Example</h3>
+    Here we again print the <tt>char</tt>s from the array <tt>characters</tt>
+    by accessing them through the array of pointers <tt>pointer_to_chars</tt>,
+    but this time we use the <tt>make_indirect_iterator()</tt> function which
+    saves us some typing. 
+
+    <blockquote>
+<pre>
+  // continuing from the last example...
+
+  std::copy(boost::make_indirect_iterator(pointers_to_chars), 
+      boost::make_indirect_iterator(pointers_to_chars + N),

+  std::cout &lt;&lt; std::endl;

+    <hr>
+
+    <h3>Notes</h3>
+
+    <p>
+
+    <p><a name="2">[2]</a> If your compiler does not support partial
+    specialization and the base iterator or its <tt>value_type</tt> is a
+    builtin pointer type, you will not be able to use the default for
+    <tt>Value</tt> and will need to specify this type explicitly.
+
+    <p><a name="3">[3]</a>There is a caveat to which concept the
+    indirect iterator can model.  If the return type of the
+    <tt>operator*</tt> for the base iterator's value type is not a
+    true reference, then strickly speaking, the indirect iterator can
+    not be a model of <a href=
+    "http://www.sgi.com/tech/stl/ForwardIterator.html">Forward
+    Iterator</a> or any of the concepts that refine it. In this case
+    the <tt>Category</tt> for the indirect iterator should be
+    specified as <tt>std::input_iterator_tag</tt>. However, even in
+    this case, if the base iterator is a random access iterator, the
+    resulting indirect iterator will still satisfy most of the
+    requirements for <a href=
+    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random
+    Access Iterator</a>.

+//            (Jeremy Siek)
+//  06 Feb 01 Removed now-defaulted template arguments where possible
+//            Updated names to correspond to new generator naming convention.
+//            Added a trivial test for make_transform_iterator().
+//            Gave traits for const iterators a mutable value_type, per std.
+//            Resurrected my original tests for indirect iterators.

+<h1>Permutation Iterator Adaptor</h1>
+<p>Defined in header <a href="../../boost/permutation_iterator.hpp">boost/permutation_iterator.hpp</a></p>
+<p>The permutation iterator adaptor provides an iterator to a permutation of a given range.
+(<a href="http://www.cut-the-knot.com/do_you_know/permutation.html">see definition of permutation</a>).
+The adaptor takes two arguments
+<ul>
+<li>an iterator to the range V on which the <a href="http://www.cut-the-knot.com/do_you_know/permutation.html">permutation</a> will be applied</li>
+<li>the reindexing scheme that defines how the elements of V will be permuted.</li>
+</ul>
+
+<p>Note that the permutation iterator is not limited to strict permutations of the given range V. 
+The distance between begin and end of the reindexing iterators is allowed to be smaller compared to the 
+size of the range V, in which case the permutation iterator only provides a permutation of a subrange of V. 
+The indexes neither need to be unique. In this same context, it must be noted that the past the end permutation iterator is 
+completely defined by means of the past-the-end iterator to the indices</p> 
+
+<h2>Synopsis</h2>
+
+<blockquote>
+<pre>
+namespace boost {
+  template &lt;class IndexIterator&gt;
+  class permutation_iterator_policies;
+
+  template &lt;class ElementIterator, class IndexIterator&gt;
+  class permutation_iterator_generator;
+
+  template &lt;class ElementIterator, class IndexIterator&gt;
+  typename permutation_iterator_generator&lt;ElementIterator, IndexIterator&gt;::type
+  make_permutation_iterator(ElementIterator&amp; base, IndexIterator&amp; indexing);
+}
+</pre>
+</blockquote>
+
+
+<h2>The Permutation Iterator Generator Class Template</h2>
+
+<p>The <code>permutation_iterator_generator</code> is a helper class whose purpose
+is to construct a permutation iterator <strong>type</strong>. This class has
+two template arguments, the first being the iterator type over the range V, the
+second being the type of the iterator over the indices.
+
+<blockquote>
+<pre>
+template &lt;class ElementIterator, class IndexIterator&gt;
+class permutation_iterator_generator
+{
+public:
+  typedef <a href="iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt...&gt; type; // the resulting permutation iterator type 
+}
+</pre>
+</blockquote>
+
+
+<h3>Template Parameters</h3>
+
+<table border>
+<tr>
+<th>Parameter</th>
+<th>Description</th>
+</tr>
+
+<tr>
+<td><tt>ElementIterator</tt></td>
+<td>The iterator over the elements to be permuted. This type must be a model
+of <a href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">RandomAccessIterator</a></td>
+</td>
+
+<tr>
+<td><tt>IndexIterator</tt></td>
+<td>The iterator over the new indexing scheme. This type must at least be a model
+of <a href="http://www.sgi.com/tech/stl/ForwardIterator.html">ForwardIterator</a>.
+The <code>IndexIterator::value_type</code> must be convertible to the 
+<code>ElementIterator::difference_type</code>.</td>
+</table>
+
+<h3>Concept Model</h3>
+The permutation iterator is always a model of the same concept as the IndexIterator.
+
+<h3>Members</h3>
+The permutation iterator implements the member functions
+and operators required for the 
+<a href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access Iterator</a>
+concept. However, the permutation iterator can only meet the complexity guarantees 
+of the same concept as the IndexIterator. Thus for instance, although the permutation
+iterator provides <code>operator+=(distance)</code>, this operation will take linear time
+in case the IndexIterator is a model of ForwardIterator instead of amortized constant time.
+
+<br>
+
+<h2><a name="make_generator_iterator">The Permutation Iterator Object Generator</a></h2>
+
+The <code>make_permutation_iterator()</code> function provides a
+convenient way to create permutation iterator objects. The function
+saves the user the trouble of explicitly writing out the iterator
+types.
+
+<blockquote>
+<pre>
+template &lt;class ElementIterator, class IndexIterator &gt;

+    Defined in header <a href=
+    "../../boost/iterator_adaptors.hpp">boost/iterator_adaptors.hpp</a> 
+
+    <p>The reverse iterator adaptor flips the direction of a base iterator's
+    motion. Invoking <tt>operator++()</tt> moves the base iterator backward and
+    invoking <tt>operator--()</tt> moves the base iterator forward. The Boost
+    reverse iterator adaptor is better to use than the
+    <tt>std::reverse_iterator</tt> class in situations where pairs of
+    mutable/constant iterators are needed (e.g., in containers) because
+    comparisons and conversions between the mutable and const versions are
+    implemented correctly.

+    <h2><a name="reverse_iterator_generator">The Reverse Iterator Type
+    Generator</a></h2>
+    The <tt>reverse_iterator_generator</tt> template is a <a href=
+    "../../more/generic_programming.html#type_generator">generator</a> of
+    reverse iterator types. The main template parameter for this class is the
+    base <tt>BidirectionalIterator</tt> type that is being adapted. In most
+    cases the associated types of the base iterator can be deduced using
+    <tt>std::iterator_traits</tt>, but in some situations the user may want to
+    override these types, so there are also template parameters for the base
+    iterator's associated types. 
+
+    <blockquote>
+<pre>
+template &lt;class <a href=
+"http://www.sgi.com/tech/stl/BidirectionalIterator.html">BidirectionalIterator</a>,
+          class Value, class Reference, class Pointer, class Category, class Distance&gt;

+};
+</pre>
+    </blockquote>
+
+    <h3>Example</h3>
+    In this example we sort a sequence of letters and then output the sequence
+    in descending order using reverse iterators. 
+
+    <blockquote>
+<pre>
+#include &lt;boost/config.hpp&gt;
+#include &lt;iostream&gt;
+#include &lt;algorithm&gt;
+#include &lt;boost/iterator_adaptors.hpp&gt;
+
+int main(int, char*[])
+{
+  char letters[] = "hello world!";
+  const int N = sizeof(letters)/sizeof(char) - 1;
+  std::cout &lt;&lt; "original sequence of letters:\t"
+      &lt;&lt; letters &lt;&lt; std::endl;
+
+  std::sort(letters, letters + N);
+
+  // Use reverse_iterator_generator to print a sequence
+  // of letters in reverse order.
+  
+  boost::reverse_iterator_generator&lt;char*&gt;::type
+    reverse_letters_first(letters + N),
+    reverse_letters_last(letters);
+
+  std::cout &lt;&lt; "letters in descending order:\t";
+  std::copy(reverse_letters_first, reverse_letters_last,
+      std::ostream_iterator&lt;char&gt;(std::cout));
+  std::cout &lt;&lt; std::endl;
+
+  // to be continued...
+</pre>
+    </blockquote>
+    The output is:

+<pre>
+original sequence of letters: hello world!
+letters in descending order:  wroolllhed!

+    <h3>Concept Model</h3>
+    The indirect iterator will model whichever <a href=
+    "http://www.sgi.com/tech/stl/Iterators.html">standard iterator concept
+    category</a> is modeled by the base iterator. Thus, if the base iterator is
+    a model of <a href=
+    "http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access
+    Iterator</a> then so is the resulting indirect iterator. If the base
+    iterator models a more restrictive concept, the resulting indirect iterator
+    will model the same concept. The base iterator must be at least a <a href=
+    "http://www.sgi.com/tech/stl/BidirectionalIterator.html">Bidirectional
+    Iterator</a> 
+
+    <h3>Members</h3>
+    The reverse 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. In addition it has the following constructor: 
+
+    <blockquote>
+<pre>
+reverse_iterator_generator::type(const BidirectionalIterator&amp; it)
+</pre>
+    </blockquote>
+
+
+    <br>
+     <br>
+     
+    <hr>
+
+    <p>
+
+    <h2><a name="make_reverse_iterator">The Reverse Iterator Object
+    Generator</a></h2>
+    The <tt>make_reverse_iterator()</tt> function provides a more convenient
+    way to create reverse iterator objects. The function saves the user the
+    trouble of explicitly writing out the iterator types. 
+
+    <blockquote>
+<pre>
+template &lt;class BidirectionalIterator&gt;
+typename reverse_iterator_generator&lt;BidirectionalIterator&gt;::type
+make_reverse_iterator(BidirectionalIterator base);
+</pre>
+    </blockquote>
+
+    <h3>Example</h3>
+    In this part of the example we use <tt>make_reverse_iterator()</tt> to
+    print the sequence of letters in reverse-reverse order, which is the
+    original order. 
+
+    <blockquote>
+<pre>
+  // continuing from the previous example...
+
+  std::cout &lt;&lt; "letters in ascending order:\t";
+  std::copy(boost::make_reverse_iterator(reverse_letters_last),
+      boost::make_reverse_iterator(reverse_letters_first),
+      std::ostream_iterator&lt;char&gt;(std::cout));
+  std::cout &lt;&lt; std::endl;
+
+  return 0;
+}
+</pre>
+    </blockquote>
+    The output is: 
+
+    <blockquote>
+<pre>
+letters in ascending order:  !dehllloorw

+    <h2><a name="interactions">Constant/Mutable Iterator Interactions</a></h2>
+
+    <p>One failing of the standard <tt><a

+<blockquote>

+<h1>Transform Iterator Adaptor</h1>
+
+Defined in header
+<a href="../../boost/iterator_adaptors.hpp">boost/iterator_adaptors.hpp</a>
+
+<p>
+The transform iterator adaptor augments an iterator by applying some
+function object to the result of dereferencing the iterator. Another
+words, the <tt>operator*</tt> of the transform iterator first
+dereferences the base iterator, passes the result of this to the
+function object, and then returns the result. The following
+<b>pseudo-code</b> shows the basic idea:
+
+<pre>
+  value_type transform_iterator::operator*() const {
+    return this->f(*this->base_iterator);
+  }
+</pre>
+
+All of the other operators of the transform iterator behave in the
+same fashion as those of the base iterator.

+<h2><a name="transform_iterator_generator">The Transform Iterator Type
+Generator</a></h2>
+
+The class <tt>transform_iterator_generator</tt> is a helper class whose
+purpose is to construct a transform iterator type.  The template
+parameters for this class are the <tt>AdaptableUnaryFunction</tt> function object
+type and the <tt>BaseIterator</tt> type that is being wrapped.
+
+<pre>
+template &lt;class AdaptableUnaryFunction, class Iterator&gt;
+class transform_iterator_generator

+public:
+    typedef <a href="./iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt;...&gt; type;
+};
+</pre>
+
+<h3>Example</h3>
+
+<p>
+The following is an example of how to use the
+<tt>transform_iterator_generator</tt> class to iterate through a range
+of numbers, multiplying each of them by 2 when they are dereferenced.
+The <tt>boost::binder1st</tt> class is used instead of the standard
+one because tranform iterator requires the function object to be
+Default Constructible.

+<PRE>
+#include &lt;functional&gt;

+    i_end(x + sizeof(x)/sizeof(int), boost::bind1st(std::multiplies&lt;int&gt;(), 2));
+
+  std::cout &lt;&lt; "multiplying the array by 2:" &lt;&lt; std::endl;

+</TR>
+
+<TR>
+<TD><a
+href="http://www.sgi.com/tech/stl/AdaptableUnaryFunction.html"><tt>AdaptableUnaryFunction</tt></a></TD>
+<TD>The function object that transforms each element in the iterator
+range.  The <tt>argument_type</tt> of the function object must match
+the value type of the base iterator.  The <tt>result_type</tt> of the
+function object will be the resulting iterator's
+<tt>value_type</tt>. If you want the resulting iterator to behave as
+an iterator, the result of the function should be solely a function of
+its argument. Also, the function object must be <a
+href="http://www.sgi.com/tech/stl/DefaultConstructible.html"> Default
+Constructible</a> (which many of the standard function objects are not).</TD>
+</TR>
+
+<TR>
+<TD><tt>BaseIterator</tt></TD>
+<TD>The iterator type being wrapped. This type must at least be a model
+ of the <a href="http://www.sgi.com/tech/stl/InputIterator">InputIterator</a> concept.</TD>
+</TR>
+
+</Table>
+
+<h3>Model of</h3>
+
+The transform iterator adaptor (the type
+<tt>transform_iterator_generator<...>::type</tt>) is a model of <a
+href="http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a><a href="#1">[1]</a>.
+
+
+<h3>Members</h3>
+
+The transform 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, except that the <tt>reference</tt> type is the same as the <tt>value_type</tt>
+so <tt>operator*()</tt> returns by-value. In addition it has the following constructor:
+
+<pre>
+transform_iterator_generator::type(const BaseIterator&amp; it,
+                                   const AdaptableUnaryFunction&amp; f = AdaptableUnaryFunction())
+</pre>
+
+<p>
+<hr>
+<p>
+
+
+<h2><a name="make_transform_iterator">The Transform Iterator Object Generator</a></h2>
+
+<pre>
+template &lt;class AdaptableUnaryFunction, class BaseIterator&gt;
+typename transform_iterator_generator&lt;AdaptableUnaryFunction,BaseIterator&gt;::type
+make_transform_iterator(BaseIterator base,
+                        const AdaptableUnaryFunction&amp; f = AdaptableUnaryFunction());
+</pre>
+
+This function provides a convenient way to create transform iterators.
+
+<h3>Example</h3>
+
+Continuing from the previous example, we use the <tt>make_transform_iterator()</tt>
+function to add four to each element of the array.
+
+<pre>
+  std::cout << "adding 4 to each element in the array:" << std::endl;
+
+  std::copy(boost::make_transform_iterator(x, boost::bind1st(std::plus<int>(), 4)),
+	    boost::make_transform_iterator(x + N, boost::bind1st(std::plus<int>(), 4)),
+	    std::ostream_iterator<int>(std::cout, " "));
+  std::cout << std::endl;
+
+  return 0;
+}
+</pre>
+The output from this part is:
+<pre>
+5 6 7 8 9 10 11 12
+</pre>
+
+<h3>Notes</h3>
+
+
+<a name="1">[1]</a> If the base iterator is a model of <a
+href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access Iterator</a>
+then the transform iterator will also suppport most of the
+functionality required by the Random Access Iterator concept. However, a
+transform iterator can never completely satisfy the requirements for
+<a
+href="http://www.sgi.com/tech/stl/ForwardIterator.html">Forward Iterator</a>
+(or of any concepts that refine Forward Iterator, which includes
+Random Access Iterator and Bidirectional Iterator) since the <tt>operator*</tt> of the transform
+iterator always returns by-value.

-
-<p>For those classes that are marked with a D or C, if compiler
-support is not provided, this type trait may return &quot;false&quot;
-when the correct value is actually &quot;true&quot;. The single
-exception to this rule is &quot;is_class&quot;, which attempts to
-guess whether or not T is really a class, and may return &quot;true&quot;
-when the correct value is actually &quot;false&quot;. This can
-happen if: T is a union, T is an enum, or T is a compiler-supplied
-scalar type that is not specialised for in these type traits.</p>
-
-<p><i>If there is no compiler support</i>, to ensure that these
-traits <i>always</i> return the correct values, specialise 'is_enum'
-for each user-defined enumeration type, 'is_union' for each user-defined
-union type, 'is_empty' for each user-defined empty composite type,
-and 'is_POD' for each user-defined POD type. The 'has_*' traits
-should also be specialized if the user-defined type has those
-traits and is <i>not</i> a POD.</p>
-
-<p>The following rules are automatically enforced:</p>
-
-<p>is_enum implies is_POD</p>
-
-<p>is_POD implies has_*</p>
-
-<p>This means, for example, if you have an empty POD-struct, just
-specialize is_empty and is_POD, which will cause all the has_* to
-also return true.</p>
-
-<h2><a name="ec"></a>Example code</h2>
-
-<p>Type-traits comes with two sample programs: <a
-href="type_traits_test.cpp">type_traits_test.cpp</a> tests the
-type traits classes - mostly this is a test of your compiler's
-support for the concepts used in the type traits implementation,
-while <a href="algo_opt_examples.cpp">algo_opt_examples.cpp</a>
-uses the type traits classes to &quot;optimise&quot; some
-familiar standard library algorithms.</p>

+
+<p>Deletion of a pointer to an incomplete type is an unsafe programming practice
+because there is no way for the compiler to verify that the destructor is indeed
+trivial.&nbsp; The checked_delete() and checked_array_delete() function
+templates simply <b>delete</b> or <b>delete[]</b> their argument, but also
+require that their argument be a complete type.&nbsp; They issue an appropriate
+compiler error diagnostic if that requirement is not met.&nbsp; A typical
+implementation is shown; other implementations may vary:</p>
+
+<pre>    template&lt; typename T &gt;
+    inline void checked_delete(T const volatile * x)
+    {
+        BOOST_STATIC_ASSERT( sizeof(T) ); // assert type complete at point
+                                          // of instantiation
+        delete x;
+    }
+
+    template&lt; typename T &gt;
+    inline void checked_array_delete(T const volatile * x)
+    {
+        BOOST_STATIC_ASSERT( sizeof(T) ); // assert type complete at point
+                                          // of instantiation
+        delete [] x;
+    }</pre>
+
+<p>Contributed by Beman Dawes, based on a suggestion from Dave Abrahams,
+generalizing an idea from Vladimir Prus, with comments from Rainer Deyke, John
+Maddock, and others.</p>
+
+<h3>Background</h3>
+
+<p>The C++ Standard specifies that delete on a pointer to an incomplete types is
+undefined behavior if the type has a non-trivial destructor in&nbsp; [expr.delete]
+5.3.5 paragraph.&nbsp; No diagnostic is required.&nbsp; Some but not all
+compilers issue warnings if the type is incomplete at point of deletion.</p>

+<p>C++ allows programmers to replace the unary
+<strong>operator&()</strong> class member used to get the address of
+an object.  Getting the real address of an object requires ugly
+casting tricks to avoid invoking the overloaded
+<strong>operator&()</strong>.  Function <strong>addressof()</strong>
+provides a wrapper around the necessary code to make it easy to get an
+object's real address.

+
+<p>The program <a href="addressof_test.cpp">addressof_test.cpp</a> can be
+used to verify that <b>addressof()</b> works as expected.</p>
