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

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

-<p>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>

+<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)

+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>

+<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;
+  typename filter_iterator_generator&lt;Predicate, BaseIterator&gt;::type

+
+<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
+</pre>

+<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>
+
+<p>
+<hr>
+<p>
+
+<h2><a name="make_filter_iterator">The Make Filter Iterator Function</a></h2>
+
+<pre>
+template &lt;class Predicate, class BaseIterator&gt;
+typename detail::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.
+
+    <h2>Synopsis</h2>
+
+    <blockquote>
+<pre>
+namespace boost {
+  template &lt;class UnaryFunction&gt;
+  class function_output_iterator;
+
+  template &lt;class UnaryFunction&gt;
+  function_output_iterator&lt;UnaryFunction&gt;
+  make_function_output_iterator(const UnaryFunction&amp; f = UnaryFunction())
+}
+</pre>
+    </blockquote>
+
+    <h3>Example</h3>
+    
+    In this example we create an output iterator that appends
+    each item onto the end of a string, using the <tt>string_appender</tt>
+    function. 
+
+    <blockquote>
+<pre>
+#include &lt;iostream&gt;
+#include &lt;string&gt;
+#include &lt;vector&gt;
+
+#include &lt;boost/function_output_iterator.hpp&gt;
+
+struct string_appender {
+  string_appender(std::string&amp; s) : m_str(s) { }
+  void operator()(const std::string&amp; x) const {
+    m_str += x;
+  }
+  std::string&amp; m_str;
+};
+
+int main(int, char*[])
+{
+  std::vector&lt;std::string&gt; x;
+  x.push_back("hello");
+  x.push_back(" ");
+  x.push_back("world");
+  x.push_back("!");
+
+  std::string s = "";
+  std::copy(x.begin(), x.end(), 
+            boost::make_function_output_iterator(string_appender(s)));
+  
+  std::cout &lt;&lt; s &lt;&lt; std::endl;
+
+  return 0;
+}

+class function_output_iterator;

+    </blockquote>
+
+    The <tt>function_output_iterator</tt> class creates an <a

+    Iterator</a> out of a
+    <a href="http://www.sgi.com/tech/stl/UnaryFunction.html">Unary

+//  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

+    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>

+    <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>

+
+    <h3>Example</h3>
+    This example uses the <tt>indirect_iterator_generator</tt> to create

+    <tt>characters</tt> array.

+    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:

+    <h3>Concept Model</h3>
+
+    The indirect iterators 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 are the resulting indirect
+    iterators. If the base iterator models a more restrictive concept,
+    the resulting indirect iterators will model the same concept <a
+    href="#3">[3]</a>.
+
+
+    <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: 
+
+    <blockquote>
+<pre>
+explicit indirect_iterator_pair_generator::iterator(const BaseIterator&amp; it)
+explicit indirect_iterator_pair_generator::const_iterator(const BaseIterator&amp; it)
+</pre>
+    </blockquote>
+    <br>
+     <br>
+     
+    <hr>
+
+    <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)  
+</pre>
+    </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::ostream_iterator&lt;char&gt;(std::cout, ","));
+  std::cout &lt;&lt; std::endl;
+
+  return 0;
+}
+</pre>
+    </blockquote>
+    The output is: 
+
+    <blockquote>
+<pre>
+a,b,c,d,e,f,g,
+</pre>
+    </blockquote>
+    <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>.

+<h1>Projection Iterator Adaptor</h1>

+
+<p>
+The projection iterator adaptor is similar to the <a
+href="./transform_iterator.htm">transform iterator adaptor</a> in that
+its <tt>operator*()</tt> applies some function to the result of
+dereferencing the base iterator and then returns the result. The
+difference is that the function must return a reference to some
+existing object (for example, a data member within the
+<tt>value_type</tt> of the base iterator). The following
+<b>pseudo-code</b> gives the basic idea. The data member <tt>p</tt> is
+the function object.

+
+In the following example we have a list of personnel records. Each

+iterator and use it to print out the names of the employees.

+    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>
+

+    <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";

+
+    <p>One failing of the standard <tt><a

+    adaptor is that it doesn't properly support interactions between adapted
+    <tt>const</tt> and non-<tt>const</tt> iterators. For example:
+<blockquote>
+<pre>
+#include &lt;vector&gt;
+
+template &lt;class T&gt; void convert(T x) {}
+
+// Test interactions of a matched pair of random access iterators
+template &lt;class Iterator, class ConstIterator&gt;

+</pre>
+</blockquote>
+Reverse iterators created with <tt>boost::reverse_iterator_generator</tt> don't have this problem, though:

+Or, more simply,

+<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.

+
+The class <tt>transform_iterator_generator</tt> is a helper class whose

+<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

+</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())

+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)
+    {
