<p>The class template <code>boost::base_from_member</code> provides
a workaround for a class that needs to initialize a base class with a
member. The class template is in <cite><a
href="../../boost/utility/base_from_member.hpp">boost/utility/base_from_member.hpp</a></cite>
which is included in <i><a href="../../boost/utility.hpp">boost/utility.hpp</a></i>.
The class template is forward declared in <i><a href="../../boost/utility_fwd.hpp">boost/utility_fwd.hpp</a></i>.</p>
<p>There is test/example code in <cite><a
href="base_from_member_test.cpp">base_from_member_test.cpp</a></cite>.</p>

<h2><a name="rationale">Rationale</a></h2>
<p>When developing a class, sometimes a base class needs to be
initialized with a member of the current class. As a na&iuml;ve
example:</p>
<blockquote><pre>
#include &lt;streambuf&gt; <i>// for std::streambuf</i>
#include &lt;ostream&gt; <i>// for std::ostream</i>
class fdoutbuf
: public std::streambuf
{
public:
explicit fdoutbuf( int fd );
//...
};
class fdostream
: public std::ostream
{
protected:
fdoutbuf buf;
public:
explicit fdostream( int fd )
: buf( fd ), std::ostream( &amp;buf )
{}
//...
};
</pre></blockquote>
<p>This is undefined because C++'s initialization order mandates that
the base class is initialized before the member it uses. Ron Klatchko
developed a way around this by using the initialization order in his
favor. Base classes are intialized in order of declaration, so moving
the desired member to another base class, that is initialized before the
desired base class, can ensure proper initialization.</p>
<p>A custom base class can be made for this idiom:</p>
<blockquote><pre>
#include &lt;streambuf&gt; <i>// for std::streambuf</i>
#include &lt;ostream&gt; <i>// for std::ostream</i>
class fdoutbuf
: public std::streambuf
{
public:
explicit fdoutbuf( int fd );
//...
};
struct fdostream_pbase
{
fdoutbuf sbuffer;
explicit fdostream_pbase( int fd )
: sbuffer( fd )
{}
};
class fdostream
: private fdostream_pbase
, public std::ostream
{
typedef fdostream_pbase pbase_type;
typedef std::ostream base_type;
public:
explicit fdostream( int fd )
: pbase_type( fd ), base_type( &amp;sbuffer )
{}
//...
};
</pre></blockquote>
<p>Other projects can use similar custom base classes. The technique is basic enough to make a template, with a sample template class in this library. The main template parameter is the type of the enclosed member. The template class has several (explicit) constructor member templates, which implicitly type the constructor arguments and pass them to the member. The template class uses implicit copy construction and assignment, cancelling them if the enclosed member is non-copyable.</p>
<p>Manually coding a base class may be better if the construction
and/or copying needs are too complex for the supplied template class,
or if the compiler is not advanced enough to use it.</p>
<p>Since base classes are unnamed, a class cannot have multiple (direct)
base classes of the same type. The supplied template class has an
extra template parameter, an integer, that exists solely to provide type
differentiation. This parameter has a default value so a single use of a
particular member type does not need to concern itself with the integer.</p>
<h2><a name="synopsis">Synopsis</a></h2>
<blockquote><pre>
template &lt; typename MemberType, int UniqueID = 0 &gt;
class boost::base_from_member
{
protected:
MemberType member;
explicit base_from_member();
template&lt; typename T1 &gt;
explicit base_from_member( T1 x1 );
//...
template&lt; typename T1, typename T2, typename T3 &gt;
explicit base_from_member( T1 x1, T2 x2, T3 x3 );
};
</pre></blockquote>
<p>The class template has a first template parameter
<var>MemberType</var> representing the type of the based-member.
It has a last template parameter <var>UniqueID</var>, that is an
<code>int</code>, to differentiate between multiple base classes that use
the same based-member type. The last template parameter has a default
value of zero if it is omitted. The class template has a protected
data member called <var>member</var> that the derived class can use
for later base classes (or itself).</p>
<p>There is a default constructor and several constructor member
templates. These constructor templates can take as many arguments
(currently up to three) as possible and pass them to a constructor of
the data member. Since C++ does not allow any way to explicitly state
the template parameters of a templated constructor, make sure that
the arguments are already close as possible to the actual type used in
the data member's desired constructor.</p>
<h2><a name="usage">Usage</a></h2>
<p>With the starting example, the <code>fdoutbuf</code> sub-object needs
to be encapsulated in a base class that is inheirited before
<code>std::ostream</code>.</p>
<blockquote><pre>
#include &lt;boost/utility/base_from_member.hpp&gt;
#include &lt;streambuf&gt; <i>// for std::streambuf</i>
#include &lt;ostream&gt; <i>// for std::ostream</i>
class fdoutbuf
: public std::streambuf
{
public:
explicit fdoutbuf( int fd );
//...
};
class fdostream
: private boost::base_from_member&lt;fdoutbuf&gt;
, public std::ostream
{
// Helper typedef's
typedef boost::base_from_member&lt;fdoutbuf&gt; pbase_type;
typedef std::ostream base_type;
public:
explicit fdostream( int fd )
: pbase_type( fd ), base_type( &amp;member )
{}
//...
};
</pre></blockquote>
<p>The base-from-member idiom is an implementation detail, so it
should not be visible to the clients (or any derived classes) of
<code>fdostream</code>. Due to the initialization order, the
<code>fdoutbuf</code> sub-object will get initialized before the
<code>std::ostream</code> sub-object does, making the former
sub-object safe to use in the latter sub-object's construction. Since the
<code>fdoutbuf</code> sub-object of the final type is the only sub-object
with the name &quot;member,&quot; that name can be used
unqualified within the final class.</p>
<h2><a name="example">Example</a></h2>
<p>The base-from-member class templates should commonly involve
only one base-from-member sub-object, usually for attaching a
stream-buffer to an I/O stream. The next example demonstrates how
to use multiple base-from-member sub-objects and the resulting
qualification issues.</p>
<blockquote><pre>
#include &lt;boost/utility/base_from_member.hpp&gt;
#include &lt;cstddef&gt; <i>// for NULL</i>
struct an_int
{
int y;
an_int( float yf );
};
class switcher
{
public:
switcher();
switcher( double, int * );
//...
};
class flow_regulator
{
public:
flow_regulator( switcher &amp;, switcher &amp; );
//...
};
template &lt; unsigned Size &gt;
class fan
{
public:
explicit fan( switcher );
//...
};
class system
: private boost::base_from_member&lt;an_int&gt;
, private boost::base_from_member&lt;switcher&gt;
, private boost::base_from_member&lt;switcher, 1&gt;
, private boost::base_from_member&lt;switcher, 2&gt;
, protected flow_regulator
, public fan&lt;6&gt;
{
// Helper typedef's
typedef boost::base_from_member&lt;an_int&gt; pbase0_type;
typedef boost::base_from_member&lt;switcher&gt; pbase1_type;
typedef boost::base_from_member&lt;switcher, 1&gt; pbase2_type;
typedef boost::base_from_member&lt;switcher, 2&gt; pbase3_type;
typedef flow_regulator base1_type;
typedef fan&lt;6&gt; base2_type;
public:
system( double x );
//...
};
system::system( double x )
: pbase0_type( 0.2 )
, pbase1_type()
, pbase2_type( -16, &amp;this-&gt;pbase0_type::member )
, pbase3_type( x, static_cast&lt;int *&gt;(NULL) )
, base1_type( pbase3_type::member, pbase1_type::member )
, base2_type( pbase2_type::member )
{
//...
}
</pre></blockquote>
<p>The final class has multiple sub-objects with the name
&quot;member,&quot; so any use of that name needs qualification by
a name of the appropriate base type. (Using <code>typedef</code>s
ease mentioning the base types.) However, the fix introduces a new
problem when a pointer is needed. Using the address operator with
a sub-object qualified with its class's name results in a pointer-to-member
(here, having a type of <code>an_int boost::base_from_member&lt;an_int,
0&gt; :: *</code>) instead of a pointer to the member (having a type of
<code>an_int *</code>). The new problem is fixed by qualifying the
sub-object with &quot;<code>this-&gt;</code>,&quot; and is needed just
for pointers, and not for references or values.</p>
<p>There are some argument conversions in the initialization. The
constructor argument for <code>pbase0_type</code> is converted from
<code>double</code> to <code>float</code>. The first constructor
argument for <code>pbase2_type</code> is converted from <code>int</code>
to <code>double</code>. The second constructor argument for
<code>pbase3_type</code> is a special case of necessary conversion; all
forms of the null-pointer literal in C++ also look like compile-time
integral expressions, so C++ always interprets such code as an integer
when it has overloads that can take either an integer or a pointer. The
last conversion is necessary for the compiler to call a constructor form
with the exact pointer type used in <code>switcher</code>'s constructor.</p>

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

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

specific useful behaviors to arbitrary base iterators.
<h2>Backward Compatibility Note</h2>
<p>The library's interface has changed since it was first released, breaking
backward compatibility:
<ol>
<li><a href="#policies">Policies classes</a> now operate on instances of the
whole <tt>iterator_adaptor</tt> object, rather than just operating on the
<tt>Base</tt> object. This change not only gives the policies class access
to both members of a pair of interacting iterators, but also eliminates the
need for the ugly <tt>type&lt;Reference&gt;</tt> and
<tt>type&lt;Difference&gt;</tt> parameters to various policy functions.
<li>The <a href="#named_template_parameters">Named Template Parameter</a>
interface has been made simpler, easier to use, and compatible with more
compilers.
</ol>
<h2>Other Documentation</h2>
<p><a href="iterator_adaptors.pdf">``Policy Adaptors and the Boost Iterator
Adaptor Library''</a> is a technical paper describing this library and the
powerful design pattern on which it is based. It was presented at the <a
href="http://www.oonumerics.org/tmpw01">C++ Template Workshop</a> at OOPSLA
2001; the slides from the talk are available <a
href="iterator_adaptors.ppt">here</a>. Please note that while the slides
incorporate the minor interface changes described in the previous section,
the paper does not.

For example, the following adapts <tt>foo_iterator</tt> to create
an <a href=

with <tt>reference</tt> type <tt>foo</tt>, and whose other traits
are determined according to the defaults described <a
href="#template_parameters">above</a>.
The <tt>iterator_traits_generator</tt> is used to create a list of
of template arguments. For example, suppose you want to set the
<tt>Reference</tt> and <tt>Category</tt> parameters, and use the
defaults for the rest. Then you can use the traits generator as
follows:
<blockquote>
<pre>
typedef iterator_adaptor&lt;foo_iterator, foo_policies,
reference_is&lt;foo&gt;, iterator_category_is&lt;std::input_iterator_tag&gt;
&gt; MyIterator;
iterator_traits_generator::reference&lt;foo&gt;::category&lt;std::input_iterator_tag&gt;
</pre>
</blockquote>
This generated type can then be passed into the <tt>iterator_adaptor</tt>
class to replace any of the last five parameters. If you use the traits
generator in the <i>i</i>th parameter position, then the parameters <i>i</i>
through 7 will use the types specified in the generator. For example, the
following adapts <tt>foo_iterator</tt> to create an <a href=
"http://www.sgi.com/tech/stl/InputIterator.html">InputIterator</a> with
<tt>reference</tt> type <tt>foo</tt>, and whose other traits are determined

Forward Iterator</a>, so you will need to use a less restrictive
iterator category such as <tt>std::input_iterator_tag</tt>.
<p><a name="6">[6]</a>
There is a common misconception that an iterator should have two
versions of <tt>operator*</tt> and of <tt>operator[]</tt>, one
version that is a <tt>const</tt> member function and one version
that is non-<tt>const</tt>. Perhaps the source of this
misconception is that containers typically have const and
non-const versions of many of their member functions. Iterators,
however, are different. A particular iterator type can be either
<i>mutable</i> or <i>constant</i> (but not both). One can assign
to and change the object pointed to by a mutable iterator whereas a
constant iterator returns constant objects when dereferenced. Whether
the iterator object itself is <tt>const</tt> has nothing to do with
whether the iterator is mutable or constant. This is analogous to
the way built-in pointer types behave. For example, one can
modify objects pointed to by a <tt>const</tt> pointer
<pre>
int* const x = new int;
int i = 3;
*x = i;
</pre>
but one cannot modify objects pointed to by a pointer
to <tt>const</tt>
<pre>
int const* x = new int;
int i = 3;
*x = i;
</pre>
<p><a name="7">[7]</a>
If you are using a compiler that does not have a version of
<tt>std::iterator_traits</tt> that works for pointers (i.e., if your
compiler does not support partial specialization) then if the
<tt>Base</tt> type is a const pointer, then the correct defaults
for the <tt>reference</tt> and <tt>pointer</tt> types can not be
deduced. You must specify these types explicitly.
<p><a name="8">[8]</a>
Exposing the base object might be considered as being dangerous.
A possible fix would require compiler support for template friends.
As this is not widely available today, the base object remains exposed for now.

<title>Permutation Iterator Adaptor Documentation</title>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<h1>Permutation Iterator Adaptor</h1>
<p>Defined in header <a href="../../boost/permutation_iterator.hpp">boost/permutation_iterator.hpp</a></p>
<p>The permutation iterator adaptor provides an iterator to a permutation of a given range.
(<a href="http://www.cut-the-knot.com/do_you_know/permutation.html">see definition of permutation</a>).
The adaptor takes two arguments
<ul>
<li>an iterator to the range V on which the <a href="http://www.cut-the-knot.com/do_you_know/permutation.html">permutation</a> will be applied</li>
<li>the reindexing scheme that defines how the elements of V will be permuted.</li>
</ul>
<p>Note that the permutation iterator is not limited to strict permutations of the given range V.
The distance between begin and end of the reindexing iterators is allowed to be smaller compared to the
size of the range V, in which case the permutation iterator only provides a permutation of a subrange of V.
The indexes neither need to be unique. In this same context, it must be noted that the past the end permutation iterator is
completely defined by means of the past-the-end iterator to the indices</p>
<h2>Synopsis</h2>
<blockquote>
<pre>
namespace boost {
template &lt;class IndexIterator&gt;
class permutation_iterator_policies;
template &lt;class ElementIterator, class IndexIterator&gt;
class permutation_iterator_generator;
template &lt;class ElementIterator, class IndexIterator&gt;
typename permutation_iterator_generator&lt;ElementIterator, IndexIterator&gt;::type
make_permutation_iterator(ElementIterator&amp; base, IndexIterator&amp; indexing);
}
</pre>
</blockquote>
<h2>The Permutation Iterator Generator Class Template</h2>
<p>The <code>permutation_iterator_generator</code> is a helper class whose purpose
is to construct a permutation iterator <strong>type</strong>. This class has
two template arguments, the first being the iterator type over the range V, the
second being the type of the iterator over the indices.
<blockquote>
<pre>
template &lt;class ElementIterator, class IndexIterator&gt;
class permutation_iterator_generator
{
public:
typedef <a href="iterator_adaptors.htm#iterator_adaptor">iterator_adaptor</a>&lt...&gt; type; // the resulting permutation iterator type
}
</pre>
</blockquote>
<h3>Template Parameters</h3>
<table border>
<tr>
<th>Parameter</th>
<th>Description</th>
</tr>
<tr>
<td><tt>ElementIterator</tt></td>
<td>The iterator over the elements to be permuted. This type must be a model
of <a href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">RandomAccessIterator</a></td>
</td>
<tr>
<td><tt>IndexIterator</tt></td>
<td>The iterator over the new indexing scheme. This type must at least be a model
of <a href="http://www.sgi.com/tech/stl/ForwardIterator.html">ForwardIterator</a>.
The <code>IndexIterator::value_type</code> must be convertible to the
<code>ElementIterator::difference_type</code>.</td>
</table>
<h3>Concept Model</h3>
The permutation iterator is always a model of the same concept as the IndexIterator.
<h3>Members</h3>
The permutation iterator implements the member functions
and operators required for the
<a href="http://www.sgi.com/tech/stl/RandomAccessIterator.html">Random Access Iterator</a>
concept. However, the permutation iterator can only meet the complexity guarantees
of the same concept as the IndexIterator. Thus for instance, although the permutation
iterator provides <code>operator+=(distance)</code>, this operation will take linear time
in case the IndexIterator is a model of ForwardIterator instead of amortized constant time.
<br>
<h2><a name="make_generator_iterator">The Permutation Iterator Object Generator</a></h2>
The <code>make_permutation_iterator()</code> function provides a
convenient way to create permutation iterator objects. The function
saves the user the trouble of explicitly writing out the iterator
types.
<blockquote>
<pre>
template &lt;class ElementIterator, class IndexIterator &gt;
typename permutation_iterator_generator&lt;ElementIterator, IndexIterator&gt;::type
make_permutation_iterator(ElementIterator&amp; base, IndexIterator&amp; indices);
</pre>
</blockquote>
<h2>Example</h2>
<blockquote>
<pre>
using namespace boost;
int i = 0;
typedef std::vector< int > element_range_type;
typedef std::list< int > index_type;
static const int element_range_size = 10;
static const int index_size = 4;
element_range_type elements( element_range_size );
for(element_range_type::iterator el_it = elements.begin() ; el_it != elements.end() ; ++el_it) *el_it = std::distance(elements.begin(), el_it);
index_type indices( index_size );
for(index_type::iterator i_it = indices.begin() ; i_it != indices.end() ; ++i_it ) *i_it = element_range_size - index_size + std::distance(indices.begin(), i_it);
std::reverse( indices.begin(), indices.end() );
typedef permutation_iterator_generator< element_range_type::iterator, index_type::iterator >::type permutation_type;
permutation_type begin = make_permutation_iterator( elements.begin(), indices.begin() );
permutation_type it = begin;
permutation_type end = make_permutation_iterator( elements.begin(), indices.end() );
std::cout << "The original range is : ";
std::copy( elements.begin(), elements.end(), std::ostream_iterator< int >( std::cout, " " ) );
std::cout << "\n";
std::cout << "The reindexing scheme is : ";

std::copy( begin, end, std::ostream_iterator< int >( std::cout, " " ) );
std::cout << "\n";
std::cout << "Elements at even indices in the permutation : ";
it = begin;
for(i = 0; i < index_size / 2 ; ++i, it+=2 ) std::cout << *it << " ";
std::cout << "\n";
std::cout << "Permutation backwards : ";

std::cout << "\n";
std::cout << "Iterate backward with stride 2 : ";
it = begin + (index_size - 1);
for(i = 0 ; i < index_size / 2 ; ++i, it-=2 ) std::cout << *it << " ";
std::cout << "\n";

Thanks: The permutation iterator is only a small addition to the superb iterator adaptors
library of David Abrahams and Jeremy Siek.

BOOKTITLE = "First Workshop on {C++} Template Programming,
Erfurt, Germany",
MONTH = "October 10",
YEAR = "2000",
URL = "http://oonumerics.org/tmpw00/",
ABSTRACT =
"Mixin-Based Programming in C++ is a powerful programming style
based on the parameterized inheritance idiom and the composition
of C++ templates. Type expressions describing specific inheritance
hierarchies can be composed either automatically using generative
programming idioms in C++ or manually. Unfortunately, the mixin-based
C++ programming techniques published to date do not adequately support
optional and alternative mixin classes with constructors expecting
varying numbers of arguments, which are common in practice. This
is because the varying base class constructors do not provide a
uniform interface on which the constructors of the derived classes
could rely. This paper discusses several partial solutions to this
problem that were proposed to date and presents a new, complete
solution. The new solution uses generative programming techniques to
automatically generate the appropriate constructors, and this way it
avoids the overhead and clumsiness of instantiating composed mixin
classes in the client code using the partial solutions. In fact,
the new solution allows users to instantiate automatically composed
mixin classes with the simplicity of instantiating concrete classes
from traditional class hierarchies. Finally, the new solution does
not suffer from the scalability problems of the partial solutions."

ABSTRACT =
"Grids are fundamental data structures for representing
geometric structures or their subdivisions. We propose a strategy
for decoupling algorithms working on grids from the details of
grid representations, using a generic programming approach in C++.
Functionality of grid data structures is captured by a small set of
primitives, divided into combinatorial and geometric ones. Special
attention is paid to the generic implementation of grid functions, which
correspond to the notion of mappings from grid elements (e. g. vertices)
to entities of a given type. Experiments indicate that the overhead
of the generic formulation is low and can be completely eliminated in
some cases."

BOOKTITLE = "First Workshop on {C++} Template Programming,
Erfurt, Germany",
MONTH = "October 10",
YEAR = "2000",
URL = "http://oonumerics.org/tmpw00/",
ABSTRACT =
"This paper proposes an alternate structure for C++ compilers.
Type analysis is removed from the compiler and replaced with a
`type system library' which is treated as source code by the
compiler. Type computations are embedded in the intermediate
language of the compiler, and partial evaluation is used to drive
type analysis and template instantiation. By making simple changes to
the behavior of the partial evaluator, a wide range of compilation
models is achieved, each with a distinct tradeoff of compile time, code
size, and code speed. These models range from pure dynamic typing --
ideal for scripting C++ -- to profile-directed template instantiation.
This approach may solve several serious problems in compiling C++:
it achieves separate compilation of templates, allows template
code to be distributed in binary form by deferring template instantiation
until run time, and reduces the code bloat associated with
templates."

MONTH = "October 10",
YEAR = "2000",
URL = "http://oonumerics.org/tmpw00/",
ABSTRACT =
"Template libraries such as the STL contain several generic algorithms
that expect functions as arguments and thereby cause frequent use of
function objects. User-defined function objects are awkward because
they must be declared as a class in namespace scope before they may
be used. In this paper, we describe a lambda function for C++, which
allows users to define function objects on the fly, without writing class
declarations. We show that, by using expression templates, the lambda
function can be implemented without hurting the runtime performance of a
program. Expression templates can also help to overcome the performance
penalties that may arise when using expressions over user-defined
types. Thus, we based our approach on PETE which is a framework
that simplifies the addition of expression template functionality to
user-defined classes."

TITLE = "Static Interfaces in {C++}",
BOOKTITLE = "First Workshop on {C++} Template Programming,
Erfurt, Germany",
MONTH = "October 10",
YEAR = "2000",
URL = "http://oonumerics.org/tmpw00/",
ABSTRACT =
"We present an extensible framework for defining and
using ``static interfaces'' in C++. Static interfaces are especially
useful as constraints on template parameters. That is, in addition to the
usual template $class T$, template definitions can specify that T ``isa''
Foo, for some static interface named Foo. These ``isa-constraints'' can be
based on either inheritance (named conformance: T publicly inherits Foo),
members (structural conformance: T has these member functions with these
signatures), or both. The constraint mechanism imposes no space or time
overheads at runtime; virtual functions are conspicuously absent from
our framework.
We demonstrate two key utilities of static interfaces. First,
constraints enable better error messages with template code. By applying
static interfaces as constraints, instantiating a template with the
wrong type is an error that can be caught at the instantiation point,
rather than later (typically in the bowels of the implementation).
Authors of template classes and template functions can also dispatch
``custom error messages'' to report named constraint violations by
clients, making debugging easier. We show examples of the improvement of
error messages when constraints are applied to STL code.
Second, constraints enable automatic compile-time dispatch of different
implementations of class or function templates based on the named
conformance properties of the template types. For example, $Set<T>$ can be
written to automatically choose the most efficient implementation: use a
hashtable implementation if ``T isa Hashable'', or else a binary search
tree if ``T isa LessThanComparable'' , or else a linked-list if merely ``T
isa EqualityComparable''. This dispatch can be completely hidden from
clients of Set, who just use $Set<T>$ as usual."

TITLE = "Concept Checking: Binding Parametric Polymorphism in {C++}",
BOOKTITLE = "First Workshop on {C++} Template Programming,
Erfurt, Germany",
MONTH = "October 10",
YEAR = "2000",
URL = "http://oonumerics.org/tmpw00/",
ABSTRACT =
"Generic programming in C++ is characterized by the use of template
parameters to represent abstract data types (or ``concepts'').
However, the C++ language itself does not provide a mechanism for
explicitly handling concepts. As a result, it can be difficult to
insure that a concrete type meets the requirements of the concept it
is supposed to represent. Error messages resulting from incorrect
use of a concrete type can be particularly difficult to decipher.
In this paper we present techniques to check parameters in generic
C++ libraries. Our techniques use standard C++ and introduce no
run-time overhead."

BOOKTITLE = "First Workshop on {C++} Template Programming,
Erfurt, Germany",
MONTH = "October 10",
YEAR = "2000",
URL = "http://oonumerics.org/tmpw00/",
ABSTRACT =
"The STL is a powerful tool for many kinds of processing. Unfortunately,
using polymorphic objects with the STL seems not to work: Polymorphic
objects stored in STL containers either get sliced (i.e. only the base
part is copied or assigned but not the derived part) or, when storing
pointers to them instead, are not destroyed. Applying algorithms to
such containers often results in the wrong thing or complex predicate
objects are needed. This article shows how to overcome at least some
of these problems using some adaptors and also outlines a possible
implementation of STL for better integration with polymorphic objects.
The improved integration just acknowledges the distinction between the
object and the entity used to maintain it."

<h2><a name="addressof">Function template addressof()</a></h2>
<p>Function <strong>addressof()</strong> returns the address of an object.</p>
<blockquote>
<pre>
template &lt;typename T&gt; inline T* addressof(T& v);
template &lt;typename T&gt; inline const T* addressof(const T& v);
template &lt;typename T&gt; inline volatile T* addressof(volatile T& v);
template &lt;typename T&gt; inline const volatile T* addressof(const volatile T& v);
</pre>
</blockquote>
<p>C++ allows programmers to replace the unary
<strong>operator&()</strong> class member used to get the address of
an object. Getting the real address of an object requires ugly
casting tricks to avoid invoking the overloaded
<strong>operator&()</strong>. Function <strong>addressof()</strong>
provides a wrapper around the necessary code to make it easy to get an
object's real address.
</p>
<p>The program <a href="addressof_test.cpp">addressof_test.cpp</a> can be
used to verify that <b>addressof()</b> works as expected.</p>
<p>Contributed by Brad King based on ideas from discussion with Doug Gregor.</p>
<h3>Example</h3>
<blockquote>
<pre>#include &lt;boost/utility.hpp&gt;
struct useless_type {};
class nonaddressable {
useless_type operator&() const;
};
void f() {
nonaddressable x;
nonaddressable* xp = boost::addressof(x);
// nonaddressable* xpe = &amp;x; /* error */
}</pre>
