-MultiPassInputIterator
-</H2>
-
-This concept is a refinement of <a
-href="http://www.sgi.com/Technology/STL/InputIterator.html">InputIterator</a>,
-adding the requirements that the iterator can be used to make multiple
-passes through a range, and that if <TT>it1 == it2</TT> and
-<TT>it1</TT> is dereferenceable then <TT>++it1 == ++it2</TT>. The
-MultiPassInputIterator is very similar to the <a
-href="http://www.sgi.com/Technology/STL/ForwardIterator.hmtl">ForwardIterator</a>. The
-only difference is that a <a
-href="http://www.sgi.com/Technology/STL/ForwardIterator.hmtl">ForwardIterator</a>
-requires the <TT>reference</TT> type to be <TT>value_type&amp;</TT>, whereas
-MultiPassInputIterator is like <a
-href="http://www.sgi.com/Technology/STL/InputIterator.html">InputIterator</a>
-in that the <TT>reference</TT> type merely has to be convertible to
-<TT>value_type</TT>.
-
-
-<h3>Design Notes</h3>
-
-comments by Valentin Bonnard:
-
-<p> I think that introducing MultiPassInputIterator isn't the right
-solution. Do you also want to define MultiPassBidirectionnalIterator
-and MultiPassRandomAccessIterator ? I don't, definitly. It only
-confuses the issue. The problem lies into the existing hierarchy of
-iterators, which mixes movabillity, modifiabillity and lvalue-ness,
-and these are clearly independant.
-
-<p> The terms Forward, Bidirectionnal and RandomAccess are about
-movabillity and shouldn't be used to mean anything else.  In a
-completly orthogonal way, iterators can be immutable, mutable, or
-neither.  Lvalueness of iterators is also orthogonal with
-immutabillity.  With these clean concepts, your MultiPassInputIterator
-is just called a ForwardIterator.
-
-<p>                
-Other translations are:<br>
-std::ForwardIterator -> ForwardIterator & LvalueIterator<br>
-std::BidirectionnalIterator -> BidirectionnalIterator & LvalueIterator<br>
-std::RandomAccessIterator -> RandomAccessIterator & LvalueIterator<br>
-
-<p>
-Note that in practice the only operation not allowed on my 
-ForwardIterator which is allowed on std::ForwardIterator is 
-<tt>&*it</tt>. I think that <tt>&*</tt> is rarely needed in generic code.
-
-<p>
-reply by Jeremy Siek:
-
-<p>
-The above analysis by Valentin is right on. Of course, there is
-the problem with backward compatibility. The current STL implementations
-are based on the old definition of ForwardIterator. The right course
-of action is to get ForwardIterator, etc. changed in the C++ standard.
-Once that is done we can drop MultiPassInputIterator.

-<h2 align="center">C++ Type traits</h2>
-<p align="center"><em>by John Maddock and Steve Cleary</em></p>
-<p align="center"><em>This is a draft of an article that will appear in a future
-issue of </em><a href="http://www.ddj.com"><em>Dr Dobb's Journal</em></a></p>
-<p>Generic programming (writing code which works with any data type meeting a
-set of requirements) has become the method of choice for providing reusable
-code. However, there are times in generic programming when &quot;generic&quot;
-just isn't good enough - sometimes the differences between types are too large
-for an efficient generic implementation. This is when the traits technique
-becomes important - by encapsulating those properties that need to be considered
-on a type by type basis inside a traits class, we can minimise the amount of
-code that has to differ from one type to another, and maximise the amount of
-generic code.</p>
-<p>Consider an example: when working with character strings, one common
-operation is to determine the length of a null terminated string. Clearly it's
-possible to write generic code that can do this, but it turns out that there are
-much more efficient methods available: for example, the C library functions <font size="2" face="Courier New">strlen</font>
-and <font size="2" face="Courier New">wcslen</font> are usually written in
-assembler, and with suitable hardware support can be considerably faster than a
-generic version written in C++. The authors of the C++ standard library realised
-this, and abstracted the properties of <font size="2" face="Courier New">char</font>
-and <font size="2" face="Courier New">wchar_t</font> into the class <font size="2" face="Courier New">char_traits</font>.
-Generic code that works with character strings can simply use <font size="2" face="Courier New">char_traits&lt;&gt;::length</font>
-to determine the length of a null terminated string, safe in the knowledge that
-specialisations of <font size="2" face="Courier New">char_traits</font> will use
-the most appropriate method available to them.</p>
-<h4>Type traits</h4>
-<p>Class <font size="2" face="Courier New">char_traits</font> is a classic
-example of a collection of type specific properties wrapped up in a single class
- what Nathan Myers termed a <i>baggage class</i>[1]. In the Boost type-traits
-library, we[2] have written a set of very specific traits classes, each of which
-encapsulate a single trait from the C++ type system; for example, is a type a
-pointer or a reference type? Or does a type have a trivial constructor, or a
-const-qualifier? The type-traits classes share a unified design: each class has
-a single member <i>value</i>, a compile-time constant that is true if the type
-has the specified property, and false otherwise. As we will show, these classes
-can be used in generic programming to determine the properties of a given type
-and introduce optimisations that are appropriate for that case.</p>
-<p>The type-traits library also contains a set of classes that perform a
-specific transformation on a type; for example, they can remove a top-level
-const or volatile qualifier from a type. Each class that performs a
-transformation defines a single typedef-member <i>type</i> that is the result of
-the transformation. All of the type-traits classes are defined inside namespace <font size="2" face="Courier New">boost</font>;
-for brevity, namespace-qualification is omitted in most of the code samples
-given.</p>
-<h4>Implementation</h4>
-<p>There are far too many separate classes contained in the type-traits library
-to give a full implementation here - see the source code in the Boost library
-for the full details - however, most of the implementation is fairly repetitive
-anyway, so here we will just give you a flavour for how some of the classes are
-implemented. Beginning with possibly the simplest class in the library, is_void&lt;T&gt;
-has a member <i>value</i> that is true only if T is void.</p>
-<pre>template &lt;typename T&gt; 
-struct is_void
-{ static const bool value = false; };
-
-template &lt;&gt; 
-struct is_void&lt;void&gt;
-{ static const bool value = true; };</pre>
-<p>Here we define a primary version of the template class <font size="2" face="Courier New">is_void</font>,
-and provide a full-specialisation when T is void. While full specialisation of a
-template class is an important technique, sometimes we need a solution that is
-halfway between a fully generic solution, and a full specialisation. This is
-exactly the situation for which the standards committee defined partial
-template-class specialisation. As an example, consider the class
-boost::is_pointer&lt;T&gt;: here we needed a primary version that handles all
-the cases where T is not a pointer, and a partial specialisation to handle all
-the cases where T is a pointer:</p>
-<pre>template &lt;typename T&gt; 
-struct is_pointer 
-{ static const bool value = false; };
-
-template &lt;typename T&gt; 
-struct is_pointer&lt;T*&gt; 
-{ static const bool value = true; };</pre>
-<p>The syntax for partial specialisation is somewhat arcane and could easily
-occupy an article in its own right; like full specialisation, in order to write
-a partial specialisation for a class, you must first declare the primary
-template. The partial specialisation contains an extra &lt;<EFBFBD>&gt; after the
-class name that contains the partial specialisation parameters; these define the
-types that will bind to that partial specialisation rather than the default
-template. The rules for what can appear in a partial specialisation are somewhat
-convoluted, but as a rule of thumb if you can legally write two function
-overloads of the form:</p>
-<pre>void foo(T);
-void foo(U);</pre>
-<p>Then you can also write a partial specialisation of the form:</p>
-<pre>template &lt;typename T&gt;
-class c{ /*details*/ };
-
-template &lt;typename T&gt;
-
-class c&lt;U&gt;{ /*details*/ };</pre>
-<p>This rule is by no means foolproof, but it is reasonably simple to remember
-and close enough to the actual rule to be useful for everyday use.</p>
-<p>As a more complex example of partial specialisation consider the class
-remove_bounds&lt;T&gt;. This class defines a single typedef-member <i>type</i>
-that is the same type as T but with any top-level array bounds removed; this is
-an example of a traits class that performs a transformation on a type:</p>
-<pre>template &lt;typename T&gt; 
-struct remove_bounds
-{ typedef T type; };
-
-template &lt;typename T, std::size_t N&gt; 
-struct remove_bounds&lt;T[N]&gt;
-{ typedef T type; };</pre>
-<p>The aim of remove_bounds is this: imagine a generic algorithm that is passed
-an array type as a template parameter, <font size="2" face="Courier New">remove_bounds</font>
-provides a means of determining the underlying type of the array. For example <code>remove_bounds&lt;int[4][5]&gt;::type</code>
-would evaluate to the type <code>int[5]</code>. This example also shows that the
-number of template parameters in a partial specialisation does not have to match
-the number in the default template. However, the number of parameters that
-appear after the class name do have to match the number and type of the
-parameters in the default template.</p>
-<h4>Optimised copy</h4>
-<p>As an example of how the type traits classes can be used, consider the
-standard library algorithm copy:</p>
-<pre>template&lt;typename Iter1, typename Iter2&gt;
-Iter2 copy(Iter1 first, Iter1 last, Iter2 out);</pre>
-<p>Obviously, there's no problem writing a generic version of copy that works
-for all iterator types Iter1 and Iter2; however, there are some circumstances
-when the copy operation can best be performed by a call to <font size="2" face="Courier New">memcpy</font>.
-In order to implement copy in terms of <font size="2" face="Courier New">memcpy</font>
-all of the following conditions need to be met:</p>
-<ul>
-  <li>Both of the iterator types Iter1 and Iter2 must be pointers.</li>
-  <li>Both Iter1 and Iter2 must point to the same type - excluding <font size="2" face="Courier New">const</font>
-    and <font size="2" face="Courier New">volatile</font>-qualifiers.</li>
-  <li>The type pointed to by Iter1 must have a trivial assignment operator.</li>
-</ul>
-<p>By trivial assignment operator we mean that the type is either a scalar
-type[3] or:</p>
-<ul>
-  <li>The type has no user defined assignment operator.</li>
-  <li>The type does not have any data members that are references.</li>
-  <li>All base classes, and all data member objects must have trivial assignment
-    operators.</li>
-</ul>
-<p>If all these conditions are met then a type can be copied using <font size="2" face="Courier New">memcpy</font>
-rather than using a compiler generated assignment operator. The type-traits
-library provides a class <i>has_trivial_assign</i>, such that <code>has_trivial_assign&lt;T&gt;::value</code>
-is true only if T has a trivial assignment operator. This class &quot;just
-works&quot; for scalar types, but has to be explicitly specialised for
-class/struct types that also happen to have a trivial assignment operator. In
-other words if <i>has_trivial_assign</i> gives the wrong answer, it will give
-the &quot;safe&quot; wrong answer - that trivial assignment is not allowable.</p>
-<p>The code for an optimised version of copy that uses <font size="2" face="Courier New">memcpy</font>
-where appropriate is given in listing 1. The code begins by defining a template
-class <i>copier</i>, that takes a single Boolean template parameter, and has a
-static template member function <font size="2" face="Courier New">do_copy</font>
-which performs the generic version of <font size="2">copy</font> (in other words
-the &quot;slow but safe version&quot;). Following that there is a specialisation
-for <i>copier&lt;true&gt;</i>: again this defines a static template member
-function <font size="2" face="Courier New">do_copy</font>, but this version uses
-memcpy to perform an &quot;optimised&quot; copy.</p>
-<p>In order to complete the implementation, what we need now is a version of
-copy, that calls <code>copier&lt;true&gt;::do_copy</code> if it is safe to use <font size="2" face="Courier New">memcpy</font>,
-and otherwise calls <code>copier&lt;false&gt;::do_copy</code> to do a
-&quot;generic&quot; copy. This is what the version in listing 1 does. To
-understand how the code works look at the code for <font size="2" face="Courier New">copy</font>
-and consider first the two typedefs <i>v1_t</i> and <i>v2_t</i>. These use <code>std::iterator_traits&lt;Iter1&gt;::value_type</code>
-to determine what type the two iterators point to, and then feed the result into
-another type-traits class <i>remove_cv</i> that removes the top-level
-const-volatile-qualifiers: this will allow copy to compare the two types without
-regard to const- or volatile-qualifiers. Next, <font size="2" face="Courier New">copy</font>
-declares an enumerated value <i>can_opt</i> that will become the template
-parameter to copier - declaring this here as a constant is really just a
-convenience - the value could be passed directly to class <font size="2" face="Courier New">copier</font>.
-The value of <i>can_opt</i> is computed by verifying that all of the following
-are true:</p>
-<ul>
-  <li>first that the two iterators point to the same type by using a type-traits
-    class <i>is_same</i>.</li>
-  <li>Then that both iterators are real pointers - using the class <i>is_pointer</i>
-    described above.</li>
-  <li>Finally that the pointed-to types have a trivial assignment operator using
-    <i>has_trivial_assign</i>.</li>
-</ul>
-<p>Finally we can use the value of <i>can_opt</i> as the template argument to
-copier - this version of copy will now adapt to whatever parameters are passed
-to it, if its possible to use <font size="2" face="Courier New">memcpy</font>,
-then it will do so, otherwise it will use a generic copy.</p>
-<h4>Was it worth it?</h4>
-<p>It has often been repeated in these columns that &quot;premature optimisation
-is the root of all evil&quot; [4]. So the question must be asked: was our
-optimisation premature? To put this in perspective the timings for our version
-of copy compared a conventional generic copy[5] are shown in table 1.</p>
-<p>Clearly the optimisation makes a difference in this case; but, to be fair,
-the timings are loaded to exclude cache miss effects - without this accurate
-comparison between algorithms becomes difficult. However, perhaps we can add a
-couple of caveats to the premature optimisation rule:</p>
-<ul>
-  <li>If you use the right algorithm for the job in the first place then
-    optimisation will not be required; in some cases, <font size="2" face="Courier New">memcpy</font>
-    is the right algorithm.</li>
-  <li>If a component is going to be reused in many places by many people then
-    optimisations may well be worthwhile where they would not be so for a single
-    case - in other words, the likelihood that the optimisation will be
-    absolutely necessary somewhere, sometime is that much higher. Just as
-    importantly the perceived value of the stock implementation will be higher:
-    there is no point standardising an algorithm if users reject it on the
-    grounds that there are better, more heavily optimised versions available.</li>
-</ul>

-<h4>Pair of References</h4>
-<p>The optimised copy example shows how type traits may be used to perform
-optimisation decisions at compile-time. Another important usage of type traits
-is to allow code to compile that otherwise would not do so unless excessive
-partial specialization is used. This is possible by delegating partial
-specialization to the type traits classes. Our example for this form of usage is
-a pair that can hold references [6].</p>
-<p>First, let us examine the definition of &quot;std::pair&quot;, omitting the
-comparision operators, default constructor, and template copy constructor for
-simplicity:</p>
-<pre>template &lt;typename T1, typename T2&gt; 
-struct pair 
-{
-  typedef T1 first_type;
-  typedef T2 second_type;
-
-  T1 first;
-  T2 second;
-
-  pair(const T1 &amp; nfirst, const T2 &amp; nsecond)
-  :first(nfirst), second(nsecond) { }
-};</pre>
-<p>Now, this &quot;pair&quot; cannot hold references as it currently stands,
-because the constructor would require taking a reference to a reference, which
-is currently illegal [7]. Let us consider what the constructor's parameters
-would have to be in order to allow &quot;pair&quot; to hold non-reference types,
-references, and constant references:</p>
-<table border="1" cellpadding="7" cellspacing="1" width="638">
-  <tr>
-    <td valign="top" width="50%">Type of &quot;T1&quot;</td>
-    <td valign="top" width="50%">Type of parameter to initializing constructor</td>
-  </tr>
-  <tr>
-    <td valign="top" width="50%">
-      <pre>T</pre>
-    </td>
-    <td valign="top" width="50%">
-      <pre>const T &amp;</pre>
-    </td>
-  </tr>
-  <tr>
-    <td valign="top" width="50%">
-      <pre>T &amp;</pre>
-    </td>
-    <td valign="top" width="50%">
-      <pre>T &amp;</pre>
-    </td>
-  </tr>
-  <tr>
-    <td valign="top" width="50%">
-      <pre>const T &amp;</pre>
-    </td>
-    <td valign="top" width="50%">
-      <pre>const T &amp;</pre>
-    </td>
-  </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>

-    <td valign="top" width="27%">Type of &quot;const T1&quot;</td>

-    </td>
-  </tr>

-      <pre>T &amp;</pre>
-    </td>
-    <td valign="top" width="27%">
-      <pre>T &amp; [8]</pre>

-    </td>
-  </tr>
-</table>
-<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>

-<p>The template class call_traits&lt;T&gt; encapsulates the
-&quot;best&quot; method to pass a parameter of some type T to or
-from a function, and consists of a collection of typedefs defined
-as in the table below. The purpose of call_traits is to ensure
-that problems like &quot;<a href="#refs">references to references</a>&quot;
-never occur, and that parameters are passed in the most efficient
-manner possible (see <a href="#examples">examples</a>). In each
-case if your existing practice is to use the type defined on the
-left, then replace it with the call_traits defined type on the
-right. Note that for compilers that do not support partial
-specialization, no benefit will occur from using call_traits: the
-call_traits defined types will always be the same as the existing
-practice in this case.</p>

-<p>Notes:</p>
-
-<ol>
-    <li>If T is already reference type, then call_traits is
-        defined such that <a href="#refs">references to
-        references</a> do not occur (requires partial
-        specialization).</li>
-    <li>If T is an array type, then call_traits defines <code>value_type</code>
-        as a &quot;constant pointer to type&quot; rather than an
-        &quot;array of type&quot; (requires partial
-        specialization). Note that if you are using value_type as
-        a stored value then this will result in storing a &quot;constant
-        pointer to an array&quot; rather than the array itself.
-        This may or may not be a good thing depending upon what
-        you actually need (in other words take care!).</li>
-    <li>If T is a small built in type or a pointer, then <code>param_type</code>
-        is defined as <code>T const</code>, instead of <code>T
-        const&amp;</code>. This can improve the ability of the
-        compiler to optimize loops in the body of the function if
-        they depend upon the passed parameter, the semantics of
-        the passed parameter is otherwise unchanged (requires
-        partial specialization).</li>

-<h3>Copy constructibility</h3>
-
-<p>The following table defines which call_traits types can always
-be copy-constructed from which other types, those entries marked
-with a '?' are true only if and only if T is copy constructible:</p>

-<h4>Example 1:</h4>
-
-<p>The following class is a trivial class that stores some type T
-by value (see the <a href="call_traits_test.cpp">call_traits_test.cpp</a>
-file), the aim is to illustrate how each of the available call_traits
-typedefs may be used:</p>
-
-<pre>template &lt;class T&gt;
-struct contained
-{
-   // define our typedefs first, arrays are stored by value
-   // so value_type is not the same as result_type:
-   typedef typename boost::call_traits&lt;T&gt;::param_type       param_type;
-   typedef typename boost::call_traits&lt;T&gt;::reference        reference;
-   typedef typename boost::call_traits&lt;T&gt;::const_reference  const_reference;
-   typedef T                                                value_type;
-   typedef typename boost::call_traits&lt;T&gt;::value_type       result_type;
-
-   // stored value:
-   value_type v_;
-   
-   // constructors:
-   contained() {}
-   contained(param_type p) : v_(p){}
-   // return byval:
-   result_type value() { return v_; }
-   // return by_ref:
-   reference get() { return v_; }
-   const_reference const_get()const { return v_; }
-   // pass value:
-   void call(param_type p){}
-
-};</pre>
-
-<h4><a name="refs"></a>Example 2 (the reference to reference
-problem):</h4>
-
-<p>Consider the definition of std::binder1st:</p>
-
-<pre>template &lt;class Operation&gt; 
-class binder1st : 
-   public unary_function&lt;Operation::second_argument_type, Operation::result_type&gt; 
-{ 
-protected: 
-   Operation op; 
-   Operation::first_argument_type value; 
-public: 
-   binder1st(const Operation&amp; x, const Operation::first_argument_type&amp; y); 
-   Operation::result_type operator()(const Operation::second_argument_type&amp; x) const; 
-}; </pre>
-
-<p>Now consider what happens in the relatively common case that
-the functor takes its second argument as a reference, that
-implies that <code>Operation::second_argument_type</code> is a
-reference type, <code>operator()</code> will now end up taking a
-reference to a reference as an argument, and that is not
-currently legal. The solution here is to modify <code>operator()</code>
-to use call_traits:</p>
-
-<pre>Operation::result_type operator()(call_traits&lt;Operation::second_argument_type&gt;::param_type x) const;</pre>
-
-<p>Now in the case that <code>Operation::second_argument_type</code>
-is a reference type, the argument is passed as a reference, and
-the no &quot;reference to reference&quot; occurs.</p>
-
-<h4><a name="ex3"></a>Example 3 (the make_pair problem):</h4>
-
-<p>If we pass the name of an array as one (or both) arguments to <code>std::make_pair</code>,
-then template argument deduction deduces the passed parameter as
-&quot;const reference to array of T&quot;, this also applies to
-string literals (which are really array literals). Consequently
-instead of returning a pair of pointers, it tries to return a
-pair of arrays, and since an array type is not copy-constructible
-the code fails to compile. One solution is to explicitly cast the
-arguments to make_pair to pointers, but call_traits provides a
-better (i.e. automatic) solution (and one that works safely even
-in generic code where the cast might do the wrong thing):</p>
-
-<pre>template &lt;class T1, class T2&gt;
-std::pair&lt;
-   typename boost::call_traits&lt;T1&gt;::value_type, 
-   typename boost::call_traits&lt;T2&gt;::value_type&gt; 
-      make_pair(const T1&amp; t1, const T2&amp; t2)
-{
-   return std::pair&lt;
-      typename boost::call_traits&lt;T1&gt;::value_type, 
-      typename boost::call_traits&lt;T2&gt;::value_type&gt;(t1, t2);
-}</pre>
-
-<p>Here, the deduced argument types will be automatically
-degraded to pointers if the deduced types are arrays, similar
-situations occur in the standard binders and adapters: in
-principle in any function that &quot;wraps&quot; a temporary
-whose type is deduced.</p>
-
-<h4><a name="ex4"></a>Example 4 (optimising fill):</h4>
-
-<p>The call_traits template will &quot;optimize&quot; the passing
-of a small built-in type as a function parameter, this mainly has
-an effect when the parameter is used within a loop body. In the
-following example (see <a href="algo_opt_examples.cpp">algo_opt_examples.cpp</a>),
-a version of std::fill is optimized in two ways: if the type
-passed is a single byte built-in type then std::memset is used to
-effect the fill, otherwise a conventional C++ implemention is
-used, but with the passed parameter &quot;optimized&quot; using
-call_traits:</p>
-
-<pre>namespace detail{
-
-template &lt;bool opt&gt;
-struct filler
-{
-   template &lt;typename I, typename T&gt;
-   static void do_fill(I first, I last, typename boost::call_traits&lt;T&gt;::param_type val);
-   {
-      while(first != last)
-      {
-         *first = val;
-         ++first;
-      }
-   }
-};
-
-template &lt;&gt;
-struct filler&lt;true&gt;
-{
-   template &lt;typename I, typename T&gt;
-   static void do_fill(I first, I last, T val)
-   {
-      memset(first, val, last-first);
-   }
-};
-
-}
-
-template &lt;class I, class T&gt;
-inline void fill(I first, I last, const T&amp; val)
-{
-   enum{ can_opt = boost::is_pointer&lt;I&gt;::value
-                   &amp;&amp; boost::is_arithmetic&lt;T&gt;::value
-                   &amp;&amp; (sizeof(T) == 1) };
-   typedef detail::filler&lt;can_opt&gt; filler_t;
-   filler_t::template do_fill&lt;I,T&gt;(first, last, val);
-}</pre>
-
-<p>Footnote: the reason that this is &quot;optimal&quot; for
-small built-in types is that with the value passed as &quot;T
-const&quot; instead of &quot;const T&amp;&quot; the compiler is
-able to tell both that the value is constant and that it is free
-of aliases. With this information the compiler is able to cache
-the passed value in a register, unroll the loop, or use
-explicitly parallel instructions: if any of these are supported.
-Exactly how much mileage you will get from this depends upon your
-compiler - we could really use some accurate benchmarking
-software as part of boost for cases like this.</p>
-
-<h3>Rationale</h3>
-
-<p>The following notes are intended to briefly describe the
-rational behind choices made in call_traits.</p>
-
-<p>All user-defined types follow &quot;existing practice&quot;
-and need no comment.</p>
-
-<p>Small built-in types (what the standard calls fundamental
-types [3.9.1]) differ from existing practice only in the <i>param_type</i>
-typedef. In this case passing &quot;T const&quot; is compatible
-with existing practice, but may improve performance in some cases
-(see <a href="#ex4">Example 4</a>), in any case this should never
-be any worse than existing practice.</p>
-
-<p>Pointers follow the same rational as small built-in types.</p>
-
-<p>For reference types the rational follows <a href="#refs">Example
-2</a> - references to references are not allowed, so the call_traits
-members must be defined such that these problems do not occur.
-There is a proposal to modify the language such that &quot;a
-reference to a reference is a reference&quot; (issue #106,
-submitted by Bjarne Stroustrup), call_traits&lt;T&gt;::value_type
-and call_traits&lt;T&gt;::param_type both provide the same effect
-as that proposal, without the need for a language change (in
-other words it's a workaround).</p>
-
-<p>For array types, a function that takes an array as an argument
-will degrade the array type to a pointer type: this means that
-the type of the actual parameter is different from its declared
-type, something that can cause endless problems in template code
-that relies on the declared type of a parameter. For example:</p>
-
-<pre>template &lt;class T&gt;
-struct A
-{
-   void foo(T t);
-};</pre>
-
-<p><font face="Times New Roman">In this case if we instantiate A&lt;int[2]&gt;
-then the declared type of the parameter passed to member function
-foo is int[2], but it's actual type is const int*, if we try to
-use the type T within the function body, then there is a strong
-likelyhood that our code will not compile:</font></p>
-
-<pre>template &lt;class T&gt;
-void A&lt;T&gt;::foo(T t)
-{
-   T dup(t); // doesn't compile for case that T is an array.
-}</pre>
-
-<p>By using call_traits the degradation from array to pointer is
-explicit, and the type of the parameter is the same as it's
-declared type:</p>
-
-<pre>template &lt;class T&gt;
-struct A
-{
-   void foo(call_traits&lt;T&gt;::value_type t);
-};
-
-template &lt;class T&gt;
-void A&lt;T&gt;::foo(call_traits&lt;T&gt;::value_type t)
-{
-   call_traits&lt;T&gt;::value_type dup(t); // OK even if T is an array type.
-}</pre>
-
-<p>For value_type (return by value), again only a pointer may be
-returned, not a copy of the whole array, and again call_traits
-makes the degradation explicit. The value_type member is useful
-whenever an array must be explicitly degraded to a pointer - <a
-href="#ex3">Example 3</a> provides the test case (Footnote: the
-array specialisation for call_traits is the least well understood
-of all the call_traits specialisations, if the given semantics
-cause specific problems for you, or don't solve a particular
-array-related problem, then I would be interested to hear about
-it. Most people though will probably never need to use this
-specialisation).</p>

-<h3>Namespace synopsis</h3>
-<blockquote>
-  <pre>namespace boost {
-    namespace cast {
-        // all synopsis below included here
-    }
-  using ::boost::cast::polymorphic_cast;
-  using ::boost::cast::polymorphic_downcast;

-  using ::boost::cast::numeric_cast;
-}</pre>
-</blockquote>
-<h3><a name="Polymorphic_cast">Polymorphic casts</a></h3>
-<p>Pointers to polymorphic objects (objects of classes which define at least one
-virtual function) are sometimes downcast or crosscast.&nbsp; Downcasting means
-casting from a base class to a derived class.&nbsp; Crosscasting means casting
-across an inheritance hierarchy diagram, such as from one base to the other in a
-<b>Y</b> diagram hierarchy.</p>
-<p>Such casts can be done with old-style casts, but this approach is never to be
-recommended.&nbsp; Old-style casts are sorely lacking in type safety, suffer
-poor readability, and are difficult to locate with search tools.</p>
-<p>The C++ built-in <b>static_cast</b> can be used for efficiently downcasting
-pointers to polymorphic objects, but provides no error detection for the case
-where the pointer being cast actually points to the wrong derived class. The <b>polymorphic_downcast</b>
-template retains the efficiency of <b>static_cast</b> for non-debug
-compilations, but for debug compilations adds safety via an assert() that a <b>dynamic_cast</b>
-succeeds.&nbsp;<b>&nbsp;</b></p>
-<p>The C++ built-in <b>dynamic_cast</b> can be used for downcasts and crosscasts
-of pointers to polymorphic objects, but error notification in the form of a
-returned value of 0 is inconvenient to test, or worse yet, easy to forget to
-test.&nbsp; The <b>polymorphic_cast</b> template performs a <b>dynamic_cast</b>,
-and throws an exception if the <b>dynamic_cast</b> returns 0.</p>
-<p>A <b>polymorphic_downcast</b> is preferred when debug-mode tests will cover
-100% of the object types possibly cast and when non-debug-mode efficiency is an
-issue. If these two conditions are not present, <b>polymorphic_cast</b> is
-preferred.&nbsp; It must also be used for crosscasts.&nbsp; It does an assert(
-dynamic_cast&lt;Derived&gt;(x) == x ) where x is the base pointer, ensuring that
-not only is a non-zero pointer returned, but also that it correct in the
-presence of multiple inheritance. .<b> Warning:</b>: Because <b>polymorphic_downcast</b>
-uses assert(), it violates the One Definition Rule if NDEBUG is inconsistently
-defined across translation units.</p>
-<p>The C++ built-in <b>dynamic_cast</b> must be used to cast references rather
-than pointers.&nbsp; It is also the only cast that can be used to check whether
-a given interface is supported; in that case a return of 0 isn't an error
-condition.</p>
-<h3>polymorphic_cast and polymorphic_downcast synopsis</h3>
-<blockquote>
-  <pre>template &lt;class Derived, class Base&gt;
-inline Derived polymorphic_cast(Base* x);
-// Throws: std::bad_cast if ( dynamic_cast&lt;Derived&gt;(x) == 0 )
-// Returns: dynamic_cast&lt;Derived&gt;(x)
-
-template &lt;class Derived, class Base&gt;
-inline Derived polymorphic_downcast(Base* x);
-// Effects: assert( dynamic_cast&lt;Derived&gt;(x) == x );
-// Returns: static_cast&lt;Derived&gt;(x)</pre>
-</blockquote>
-<h3>polymorphic_downcast example</h3>
-<blockquote>
-  <pre>#include &lt;boost/cast.hpp&gt;
-...
-class Fruit { public: virtual ~Fruit(){}; ... };
-class Banana : public Fruit { ... };
-...
-void f( Fruit * fruit ) {
-// ... logic which leads us to believe it is a Banana
-  Banana * banana = boost::polymorphic_downcast&lt;Banana*&gt;(fruit);
-  ...</pre>
-</blockquote>
-<h3><a name="numeric_cast">numeric_cast</a></h3>
-<p>A <b>static_cast</b>, <b>implicit_cast</b> or implicit conversion will not
-detect failure to preserve range for numeric casts. The <b>numeric_cast</b>
-template function are similar to <b>static_cast</b> and certain (dubious)
-implicit conversions in this respect, except that they detect loss of numeric
-range. An exception is thrown when a runtime value preservation check fails.</p>
-<p>The requirements on the argument and result types are:</p>
-<blockquote>
-  <ul>
-    <li>Both argument and result types are CopyConstructible [20.1.3].</li>
-    <li>Both argument and result types are Numeric, defined by <code>std::numeric_limits&lt;&gt;::is_specialized</code>
-      being true.</li>
-    <li>The argument can be converted to the result type using <b>static_cast</b>.</li>
-  </ul>
-</blockquote>
-<h3>numeric_cast synopsis</h3>
-<blockquote>
-  <pre>class bad_numeric_cast : public std::bad_cast {...};
-
-template&lt;typename Target, typename Source&gt;
-  inline Target numeric_cast(Source arg);
-    // Throws:  bad_numeric_cast unless, in converting arg from Source to Target,
-    //          there is no loss of negative range, and no underflow, and no
-    //          overflow, as determined by std::numeric_limits
-    // Returns: static_cast&lt;Target&gt;(arg)</pre>
-</blockquote>
-<h3>numeric_cast example</h3>
-<blockquote>
-  <pre>#include &lt;boost/cast.hpp&gt;
-using namespace boost::cast;
-
-void ariane(double vx)
-{
-    ...
-    unsigned short dx = numeric_cast&lt;unsigned short&gt;(vx);
-    ...
-}</pre>
-</blockquote>
-<h3>numeric_cast rationale</h3>
-<p>The form of the throws condition is specified so that != is not a required
-operation.</p>

-
-<p>All of the contents of &lt;boost/compressed_pair.hpp&gt; are
-defined inside namespace boost.</p>
-
-<p>The class compressed pair is very similar to std::pair, but if
-either of the template arguments are empty classes, then the
-&quot;empty member optimisation&quot; is applied to compress the
-size of the pair.</p>
-
-<pre>template &lt;class T1, class T2&gt;
-class compressed_pair
-{
-public:
-	typedef T1                                                 first_type;
-	typedef T2                                                 second_type;
-	typedef typename call_traits&lt;first_type&gt;::param_type       first_param_type;
-	typedef typename call_traits&lt;second_type&gt;::param_type      second_param_type;
-	typedef typename call_traits&lt;first_type&gt;::reference        first_reference;
-	typedef typename call_traits&lt;second_type&gt;::reference       second_reference;
-	typedef typename call_traits&lt;first_type&gt;::const_reference  first_const_reference;
-	typedef typename call_traits&lt;second_type&gt;::const_reference second_const_reference;
-
-	         compressed_pair() : base() {}
-	         compressed_pair(first_param_type x, second_param_type y);
-	explicit compressed_pair(first_param_type x);
-	explicit compressed_pair(second_param_type y);
-
-	first_reference       first();
-	first_const_reference first() const;
-
-	second_reference       second();
-	second_const_reference second() const;
-
-	void swap(compressed_pair&amp; y);
-};</pre>
-
-<p>The two members of the pair can be accessed using the member
-functions first() and second(). Note that not all member
-functions can be instantiated for all template parameter types.
-In particular compressed_pair can be instantiated for reference
-and array types, however in these cases the range of constructors
-that can be used are limited. If types T1 and T2 are the same
-type, then there is only one version of the single-argument
-constructor, and this constructor initialises both values in the
-pair to the passed value.</p>
-
-<p>Note that compressed_pair can not be instantiated if either of
-the template arguments is an enumerator type, unless there is
-compiler support for boost::is_enum, or if boost::is_enum is
-specialised for the enumerator type.</p>
-
-<p>Finally, compressed_pair requires compiler support for partial
-specialisation of class templates - without that support
-compressed_pair behaves just like std::pair.</p>

-//            partial specialization (Beman Dawes)
-//  10 Nov 99 Initial version
-
-// 10 Jun 00:
-// An additional optional template parameter was added to most of 
-// operator templates to support the base class chaining technique (see 
-// documentation for the details). Unfortunately, a straightforward
-// implementation of this change would have broken compatibility with the
-// previous version of the library by making it impossible to use the same
-// template name (e.g. 'addable') for both the 1- and 2-argument versions of
-// an operator template. This implementation solves the backward-compatibility
-// issue at the cost of some simplicity.
-//
-// One of the complications is an existence of special auxiliary class template
-// 'is_chained_base<>' (see 'detail' namespace below), which is used
-// to determine whether its template parameter is a library's operator template
-// or not. You have to specialize 'is_chained_base<>' for each new 
-// operator template you add to the library.
-//
-// However, most of the non-trivial implementation details are hidden behind 
-// several local macros defined below, and as soon as you understand them,
-// you understand the whole library implementation.

-Abrahams</a> started the library, coming up with the idea to use

-<h3><a name="iterator_adaptors">The Iterator Adaptors Class</a></h3>
-
-Implementing standard conforming iterators is a non-trivial task.
-There are some fine-points such as iterator/const_iterator
-interactions and there are the myriad of operators that should be
-implemented but are easily forgotten such as
-<tt>operator-&gt;()</tt>. The purpose of the
-<tt>iterator_adaptors</tt> class is to make it easier to implement an
-iterator class, and even easier to extend and adapt existing iterator
-types. The <tt>iterator_adaptors</tt> class itself is not an adaptor
-class but a <i>type generator</i>. It generates a pair of adaptor classes,
-one class for the mutable iterator and one class for the const
-iterator. The definition of the <tt>iterator_adaptors</tt> class is as
-follows:
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
-<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
-<PRE>
-template &lt;class Iterator, 
-          class ConstIterator, 
-          class Traits = std::iterator_traits&lt;Iterator&gt;,
-          class ConstTraits = std::iterator_traits&lt;ConstIterator&gt;, 
-          class Policies = default_iterator_policies&gt;
-struct iterator_adaptors
-{
-  typedef ... iterator;
-  typedef ... const_iterator;
-};
-</PRE></TD></TABLE>
-
-<p>The <tt>Iterator</tt> and <tt>ConstIterator</tt> template parameters
-are the iterator types that you want to adapt. The <tt>Traits</tt> and
-<tt>ConstTraits</tt> must be iterator traits classes.  The traits
-parameters default to the specialization of the
-<tt>std::iterator_traits</tt> class for the adapted iterators. If you
-want the traits for your new iterator adaptor (<tt>value_type</tt>,
-<tt>iterator_category</tt>, etc.) to be the same as the adapted
-iterator then use the default, otherwise create your own traits
-classes and pass them in <a href="#1">[1]</a>. 
-
-
-<p>The <tt>Policies</tt> class that you pass in will become the heart of
-the iterator adaptor. The policy class determines how your new adaptor
-class will behave. The <tt>Policies</tt> class must implement 3, 4, or
-7 of the core iterator operations depending on whether you wish the
-new iterator adaptor class to be a
-<a href="http://www.sgi.com/Technology/STL/ForwardIterator.html">
-ForwardIterator</a>,
-<a href="http://www.sgi.com/Technology/STL/BidirectionalIterator.html">
-BidirectionalIterator</a>, or <a
-href="http://www.sgi.com/Technology/STL/RandomAccessIterator.html">
-RandomAccessIterator</a>. Make sure that the
-<tt>iterator_category</tt> type of the traits class you pass in
-matches the category of iterator that you want to create. The default
-policy class, <tt>default_iterator_policies</tt>, implements all 7 of
-the core operations in the usual way. If you wish to create an
-iterator adaptor that only changes a few of the iterator's behaviors,
-then you can have your new policy class inherit from
-<tt>default_iterator_policies</tt> to avoid retyping the usual
-behaviours. You should also look at <tt>default_iterator_policies</tt>
-as the &quot;boiler-plate&quot; for your own policy classes. The
-following is definition of the <tt>default_iterator_policies</tt>
-class:
-
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>

-{

-<h3><a name="iterator_adaptor">The Iterator Adaptor Class</a></h3>
-
-This is the class used inside of the <tt>iterator_adaptors</tt> type
-generator. Use this class directly (instead of using
-<tt>iterator_adaptors</tt>) when there is no difference between the
-const and non-const versions of the iterator type. Often this is
-because there is only a const (read-only) version of the iterator, as
-is the case for <tt>std::set</tt>'s iterators. Use the same type for
-the <tt>Iterator</tt> and <tt>NonconstIterator</tt> template
-arguments.
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
-<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
-<PRE>
-template &lt;class Iterator, 
-          class Policies = default_iterator_policies,

-struct iterator_adaptor;
-</PRE></TD></TABLE>
-
-
-<p>
-Next we will look at some iterator adaptors that are examples of how
-to use the iterator adaptors class, and that are useful iterator
-adaptors in their own right.
-
-<h3><a name="transform_iterator">The Transform Iterator Class</a></h3>
-
-It is often useful to automatically apply some function to the value
-returned by dereferencing (<tt>operator*()</tt>) an iterator. The
-<tt>transform_iterators</tt> class makes it easy to create an iterator
-adaptor that does just that.
-
-First let us consider what the <tt>Policies</tt> class for the transform
-iterator should look like. We are only changing one of the iterator
-behaviours, so we will inherit from
-<tt>default_iterator_policies</tt>. In addition, we will need a
-function object to apply, so we will have a template parameter and a
-data member for the function object. The function will take one
-argument (the dereferenced value) and we will need to know the
-<tt>result_type</tt> of the function, so <a
-href="http://www.sgi.com/Technology/STL/AdaptableUnaryFunction.html">
-AdaptableUnaryFunction</a> is the corrent concept to choose for the
-function object type. Now for the heart of our iterator adaptor, we
-implement the <tt>dereference</tt> method, applying the function
-object to <tt>*i</tt>. The <tt>type&lt;Reference&gt;</tt> class is
-there to tell you what the reference type of the iterator is, which is
-handy when writing generic iterator adaptors such as this one <a
-href="#2">[2]</a>.
-
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
-<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
-<PRE>
-  template &lt;class AdaptableUnaryFunction&gt;
-  struct transform_iterator_policies : public default_iterator_policies
-  {
-    transform_iterator_policies(const AdaptableUnaryFunction& f) : m_f(f) { }
-
-    template &lt;class Reference, class Iterator&gt;
-    Reference dereference(type&lt;Reference&gt;, const Iterator& i) const
-      { return m_f(*i); }
-
-    AdaptableUnaryFunction m_f;
-  };
-</PRE></TD></TABLE>
-
-Next we need to create the traits class for our new iterator.  In some
-situations you may need to create a separate traits class for the
-const and non-const iterator types, but here a single traits class
-will do. The <tt>value_type</tt> and <tt>reference</tt> type of our
-transform iterator will be the <tt>result_type</tt> of the function
-object.  The <tt>difference_type</tt> and <tt>iterator_category</tt>
-will be the same as the adapted iterator.
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
-<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
-<PRE>
-  template &lt;class AdaptableUnaryFunction, class IteratorTraits&gt;
-  struct transform_iterator_traits {
-    typedef typename AdaptableUnaryFunction::result_type value_type;
-    typedef value_type reference;
-    typedef value_type* pointer;
-    typedef typename IteratorTraits::difference_type difference_type;
-    typedef typename IteratorTraits::iterator_category iterator_category;
-  };
-</PRE></TD></TABLE>
-
-The final step is to use the <tt>iterator_adaptor</tt> class to
-construct our transform iterator. We will use the single iterator
-adaptor version because we will not need to create both a mutable and
-const version of the transform iterator. The transform iterator is
-inherently a read-only iterator.  The nicest way to package up our new
-transform iterator is to create a type generator similar to
-<tt>iterator_adaptor</tt>. The first template parameter will be the
-type of the function object. The second parameter will be the adapted
-iterator type. The third parameter is the trait class for
-the adapted iterator.  Inside the <tt>transform_iterators</tt> class
-we use the <tt>transform_iterator_traits</tt> class defined above to
-create the traits class for the new transform iterator. We then use
-the <tt>iterator_adaptor</tt> class to extract the generated
-iterator adaptor type.
-
-<p>

-<h3><a name="indirect_iterators">The Indirect Iterators Class</a></h3>
-
-It is not all that uncommon to create data structures that consist of
-pointers to pointers. For such a structure it might be nice to have an
-iterator that applies a double-dereference inside the
-<tt>operator*()</tt>. The implementation of this is similar to the
-<tt>transform_iterators</tt><a href="#3">[3]</a>. We first create a
-policies class which does a double-dereference in the
-<tt>dereference()</tt> method. We then create a traits class, this
-time also including a template parameter for the traits of the second
-level iterators as well as the first. Lastly we wrap this up in the
-type generator <tt>indirect_iterators</tt>, using
-<tt>iterator_adaptors</tt> to do most of the work.

-<h3><a name="reverse_iterators">The Reverse Iterators Class</a></h3>
-
-<p>
-Yes, there is already a <tt>reverse_iterator</tt> adaptor class
-defined in the C++ Standard, but using the <tt>iterator_adaptors</tt>
-class we can re-implement this classic adaptor in a more succinct and
-elegant fashion. Also, this makes for a good example of using
-<tt>iterator_adaptors</tt> that is in familiar territory.
-
-<p>
-The first step is to create the <tt>Policies</tt> class. As in the
-<tt>std::reverse_iterator</tt> class, we need to flip all the
-operations of the iterator. Increment will become decrement, advancing
-by <tt>n</tt> will become retreating by <tt>n</tt>, etc.

-<h3><a name="integer_range">The Integer Range Class</a></h3>
-
-The <tt>iterator_adaptors</tt> class can not only be used for adapting
-iterators, but it can also be used to take a non-iterator type and use
-it to build an iterator. An especially simple example of this is
-turning an integer type into an iterator, a counting iterator. The
-builtin integer types of C++ are almost iterators. They have
-<tt>operator++()</tt>, <tt>operator--()</tt>, etc. The one operator
-they are lacking is the <tt>operator*()</tt>, which we will want to
-simply return the current value of the integer. The following few
-lines of code implement the policy and traits class for the counting
-iterator.

-<h3>Challenge</h3>
-
-<p>
-There is an unlimited number of ways the the
-<tt>iterator_adaptors</tt> class can be used to create iterators. One
-interesting exercise would be to re-implement the iterators of
-<tt>std::list</tt> and <tt>std::slist</tt> using
-<tt>iterator_adaptors</tt>, where the adapted <tt>Iterator</tt> types
-would be node pointers.
-
-
-<h3>Notes</h3>
-
-<p>
-<a name="1">[1]</a>
-If your compiler does not support partial specialization and hence
-does not have a working <tt>std::iterator_traits</tt> class, you will
-not be able to use the defaults and will need to supply your own
-<tt>Traits</tt> and <tt>ConstTraits</tt> classes.
-
-<p>
-<a name="2">[2]</a>
-The reference type could also be obtained from
-<tt>std::iterator_traits</tt>, but that is not portable on compilers
-that do not support partial specialization.
-
-<p>
-<a name="3">[3]</a>
-It would have been more elegant to implement <tt>indirect_iterators</tt>
-using <tt>transform_iterators</tt>, but for subtle reasons that would require
-the use of <tt>boost::remove_cv</tt> which is not portable.
-
-<h3>Implementation Notes</h3>
-
-The code is somewhat complicated because there are three iterator
-adaptor class: <tt>forward_iterator_adaptor</tt>,
-<tt>bidirectional_iterator_adaptor</tt>, and
-<tt>random_access_iterator_adaptor</tt>. The alternative would be to
-just have one iterator adaptor equivalent to the
-<tt>random_access_iterator_adaptor</tt>.  The reason for going with
-the three adaptors is that according to 14.5.3p5 in the C++ Standard,
-friend functions defined inside a template class body are instantiated
-when the template class is instantiated. This means that if we only
-used the one iterator adaptor, then if the adapted iterator did not
-meet all of the requirements for a
-<a href="http://www.sgi.com/Technology/STL/RandomAccessIterator.html">
-RandomAccessIterator</a> then a compiler error should occur.  Many
-current compilers in fact do not instantiate the friend functions
-unless used, so we could get away with the one iterator adaptor in
-most cases. However, out of respect for the standard this implementation
-uses the three adaptors.

-<h2>Rationale</h2>
-<p>Overloaded operators for class types typically occur in groups. If you can
-write <code>x + y</code>, you probably also want to be able to write <code>x +=
-y</code>. If you can write <code>x &lt; y,</code> you also want <code>x &gt; y,
-x &gt;= y,</code> and <code>x &lt;= y</code>. Moreover, unless your class has
-really surprising behavior, some of these related operators can be defined in
-terms of others (e.g. <code>x &gt;= y <b>&lt;=&gt;</b> !(x &lt; y)</code>).
-Replicating this boilerplate for multiple classes is both tedious and
-error-prone. The <a href="file:///c:/boost/site/boost/operators.hpp">boost/operators.hpp</a>
-templates help by generating operators for you at namespace scope based on other
-operators you've defined in your class.</p>
-<a name="two_arg">
-<h2>Two-Argument Template Forms</h2>
-</a>
-<p>The arguments to a binary operator commonly have identical types, but it is
-not unusual to want to define operators which combine different types. For <a href="#usage">example</a>,
-one might want to multiply a mathematical vector by a scalar. The two-argument
-template forms of the arithmetic operator templates are supplied for this
-purpose. When applying the two-argument form of a template, the desired return
-type of the operators typically determines which of the two types in question
-should be derived from the operator template. For example, if the result of <code>T&nbsp;+&nbsp;U</code>
-is of type <code>T</code>, then <code>T</code> (not <code>U</code>) should be
-derived from <code>addable&lt;T,U&gt;</code>. The comparison templates <code><a href="#less_than_comparable">less_than_comparable&lt;&gt;</a></code>
-and <code><a href="#equality_comparable">equality_comparable&lt;&gt;</a></code>
-are exceptions to this guideline, since the return type of the operators they
-define is <code>bool</code>.</p>
-<p>On compilers which do not support partial specialization, the two-argument
-forms must be specified by using the names shown below with the trailing <code>'2'</code>.
-The single-argument forms with the trailing <code>'1'</code> are provided for
-symmetry and to enable certain applications of the <a href="#chaining">base
-class chaining</a> technique.</p>
-<h2>Arithmetic operators table</h2>
-<p>The requirements for the types used to instantiate operator templates are
-specified in terms of expressions which must be valid and by the return type of
-the expression. In the following table <code>t</code> and <code>t1</code> are
-values of type <code>T</code>, and <code>u</code> is a value of type <code>U</code>.
-Every template in the library other than <a href="#operators"><code>operators&lt;&gt;</code></a>
-and <a href="#operators"><code>operators2&lt;&gt;</code></a> has an additional
-optional template parameter <code>B</code> which is not shown in the table, but
-is explained <a href="#chaining">below</a></p>

-<b><a name="portability">Portability Note:</a></b> many compilers (e.g. MSVC6.3,
-GCC 2.95.2) will not enforce the requirements in this table unless the
-operations which depend on them are actually used. This is not
-standard-conforming behavior. If you are trying to write portable code it is
-important not to rely on this bug. In particular, it would be convenient to
-derive all your classes which need binary operators from the <a href="#operators"><code>operators&lt;&gt;</code></a>
-and <a href="#operators"><code>operators2&lt;&gt;</code></a> templates,
-regardless of whether they implement all the requirements in the table. Even if
-this works with your compiler today, it may not work tomorrow.
-<h2><a name="chaining">Base Class Chaining</a> and Object Size</h2>
-<p>Every template listed in the table except <a href="#operators"><code>operators&lt;&gt;</code></a>
-and <a href="#operators"><code>operators2&lt;&gt;</code></a> has an additional
-optional template parameter <code>B</code>.&nbsp; If supplied, <code>B</code>
-must be a class type; the resulting class will be publicly derived from B. This
-can be used to avoid the object size bloat commonly associated with multiple
-empty base classes (see the <a href="#old_lib_note">note for users of older
-versions</a> below for more details). To provide support for several groups of
-operators, use the additional parameter to chain operator templates into a
-single-base class hierarchy, as in the following <a href="#usage">example</a>.</p>
-<p><b>Caveat:</b> to chain to a base class which is <i>not</i> a boost operator
-template when using the <a href="#two_arg">single-argument form</a><a> of a
-boost operator template, you must specify the operator template with the
-trailing <code>'1'</code> in its name. Otherwise the library will assume you
-mean to define a binary operation combining the class you intend to use as a
-base class and the class you're deriving.</p>
-<p><b>Borland users</b>: even single-inheritance seems to cause an increase in
-object size in some cases. If you are not defining a template, you may get
-better object-size performance by avoiding derivation altogether, and instead
-explicitly instantiating the operator template as follows:
-<pre>
-    class myclass // lose the inheritance...
-    {
-        //...
-    };
-    // explicitly instantiate the operators I need.
-    template class less_than_comparable&lt;myclass&gt;;
-    template class equality_comparable&lt;myclass&gt;;

-<p>The <a href="#dereference">dereference operators</a> were motivated by the <a href="#Iterator helpers">iterator
-helpers</a>, but are often useful in non-iterator contexts as well. Many of the
-redundant iterator operators are also arithmetic operators, so the iterator
-helper classes borrow many of the operators defined above. In fact, only two new
-operators need to be defined! (the pointer-to-member <code>operator-&gt;</code>
-and the subscript <code>operator[]</code>). </PP>

-<h2><a name="old_lib_note">Note for users of older versions</a></h2>
-<p>The <a href="#chaining">changes in the library interface and recommended
-usage</a> were motivated by some practical issues described below. The new
-version of the library is still backward-compatible with the former one (so
-you're not <i>forced</i> change any existing code), but the old usage is
-deprecated. Though it was arguably simpler and more intuitive than using <a href="#chaining">base
-class chaining</a>, it has been discovered that the old practice of deriving
-from multiple operator templates can cause the resulting classes to be much
-larger than they should be. Most modern C++ compilers significantly bloat the
-size of classes derived from multiple empty base classes, even though the base
-classes themselves have no state. For instance, the size of <code>point&lt;int&gt;</code>
-from the <a href="#usage">example</a> above was 12-24 bytes on various compilers
-for the Win32 platform, instead of the expected 8 bytes.
-<p>Strictly speaking, it was not the library's fault - the language rules allow
-the compiler to apply the empty base class optimization in that situation. In
-principle an arbitrary number of empty base classes can be allocated at the same
-offset, provided that none of them have a common ancestor (see section 10.5 [class.derived],
-par. 5 of the standard). But the language definition also doesn't <i>require</i>
-implementations to do the optimization, and few if any of today's compilers
-implement it when multiple inheritance is involved. What's worse, it is very
-unlikely that implementors will adopt it as a future enhancement to existing
-compilers, because it would break binary compatibility between code generated by
-two different versions of the same compiler. As Matt Austern said, &quot;One of
-the few times when you have the freedom to do this sort of thing is when you're
-targeting a new architecture...&quot;. On the other hand, many common compilers
-will use the empty base optimization for single inheritance hierarchies.</p>
-<p>Given the importance of the issue for the users of the library (which aims to
-be useful for writing light-weight classes like <code>MyInt</code> or <code>point&lt;&gt;</code>),
-and the forces described above, we decided to change the library interface so
-that the object size bloat could be eliminated even on compilers that support
-only the simplest form of the empty base class optimization. The current library
-interface is the result of those changes. Though the new usage is a bit more
-complicated than the old one, we think it's worth it to make the library more
-useful in real world. Alexy Gurtovoy contributed the code which supports the new
-usage idiom while allowing the library remain backward-compatible.</p>

-This is a utility function that makes it more convenient to work with
-a function which returns a pair. The effect of the <TT>tie()</TT>
-function is to allow the assignment of the two values of the pair to
-two separate variables. The idea for this comes from Jaakko

-
-<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>Template <a name="functions next">functions next</a>() and prior()</h2>
-
-<p>Certain data types, such as the C++ Standard Library's forward and
-bidirectional iterators, do not provide addition and subtraction via operator+()
-or operator-().&nbsp; This means that non-modifying computation of the next or
-prior value requires a temporary, even though operator++() or operator--() is
-provided.&nbsp; It also means that writing code like <code>itr+1</code> inside a
-template restricts the iterator category to random access iterators.</p>
-
-<p>The next() and prior() functions provide a simple way around these problems:</p>
-
-<blockquote>
-
-<pre>template &lt;class T&gt;
-T next(T x) { return ++x; }
-
-template &lt;class X&gt;
-T prior(T x) { return --x; }</pre>
-
-</blockquote>
-
-<p>Usage is simple:</p>
-
-<blockquote>
-
-<pre>const std::list&lt;T&gt;::iterator p = get_some_iterator();
-const std::list&lt;T&gt;::iterator prev = boost::prior(p);</pre>

-<h2><a name="Class noncopyable">Class noncopyable</a></h2>
-
-<p>Class <strong>noncopyable</strong> is a base class.&nbsp; Derive your own class from <strong>noncopyable</strong>
-when you want to prohibit copy construction and copy assignment.</p>
-
-<p>Some objects, particularly those which hold complex resources like files or
-network connections, have no sensible copy semantics.&nbsp; Sometimes there are
-possible copy semantics, but these would be of very limited usefulness and be
-very difficult to implement correctly.&nbsp; Sometimes you're implementing a class that doesn't need to be copied
-just yet and you don't want to take the time to write the appropriate functions.&nbsp;
-Deriving from <b> noncopyable</b> will prevent the otherwise implicitly-generated
-functions (which don't have the proper semantics) from becoming a trap for other programmers.</p>
-
-<p>The traditional way to deal with these is to declare a private copy constructor and copy assignment, and then
-document why this is done.&nbsp; But deriving from <b>noncopyable</b> is simpler
-and clearer, and doesn't require additional documentation.</p>
-
-<p>The program <a href="noncopyable_test.cpp">noncopyable_test.cpp</a> can be
-used to verify class <b>noncopyable</b> works as expected. It has have been run successfully under
-GCC 2.95, Metrowerks
-CodeWarrior 5.0, and Microsoft Visual C++ 6.0 sp 3.</p>

-<h3>Example</h3>
-<blockquote>
-  <pre>// inside one of your own headers ...
-#include &lt;boost/utility.hpp&gt;
-
-class ResourceLadenFileSystem : noncopyable {
-...</pre>
-</blockquote>
-
-<h3>Rationale</h3>
-<p>Class noncopyable has protected constructor and destructor members to
-emphasize that it is to be used only as a base class.&nbsp; Dave Abrahams notes
-concern about the effect on compiler optimization of adding (even trivial inline)
-destructor declarations. He says &quot;Probably this concern is misplaced, because
-noncopyable will be used mostly for classes which own resources and thus have non-trivial destruction semantics.&quot;</p>
