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

Broken Compiler Notes
=====================
Because of workarounds in Boost, you may find that these
metafunctions_ actually work better than the facilities provided by
your compiler's standard library.
On compilers that don't support partial specialization, such as
Microsoft Visual C++ 6.0 or 7.0, you may need to manually invoke
BOOST_BROKEN_COMPILER_TYPE_TRAITS_SPECIALIZATION_ on the
``value_type`` of pointers that are passed to these metafunctions.
Because of bugs in the implementation of GCC-2.9x, the name of
``iterator_category`` is changed to ``iterator_category_`` on that
compiler. A macro, ``BOOST_ITERATOR_CATEGORY``, that expands to
either ``iterator_category`` or ``iterator_category_``, as
appropriate to the platform, is provided for portability.

[endsect] [h2 Broken Compiler Notes]
Because of workarounds in Boost, you may find that these
[@../../mpl/doc/index.html#metafunctions metafunctions] actually work better than the facilities provided by
your compiler's standard library.
On compilers that don't support partial specialization, such as
Microsoft Visual C++ 6.0 or 7.0, you may need to manually invoke
[@../../type_traits/index.html#transformations BOOST_BROKEN_COMPILER_TYPE_TRAITS_SPECIALIZATION] on the
`value_type` of pointers that are passed to these metafunctions.
Because of bugs in the implementation of GCC-2.9x, the name of
`iterator_category` is changed to `iterator_category_` on that
compiler. A macro, `BOOST_ITERATOR_CATEGORY`, that expands to
either `iterator_category` or `iterator_category_`, as
appropriate to the platform, is provided for portability.

The library provides several utilities to simplify conversions between iterator categories
and traversal tags:
* `iterator_category_to_traversal<C>::type` - the metafunction takes an iterator category `C` and returns
the corresponding traversal tag.
* `iterator_traversal<T>::type` - a shorthand for `iterator_category_to_traversal<iterator_category<T>::type>::type`.
* `pure_traversal_tag<T>::type` - the metafunction takes a tag `T` which derives from one of the iterator traversal tags
and returns that traversal tag. `T` may also derive from other tags describing the iterator (e.g. whether this is a `const`-iterator
or not), these additional tags are not considered.

Dereferencing the zip iterator returns a tuple that contains Dereferencing the zip iterator returns a tuple that contains
the results of dereferencing the individual iterators. the results of dereferencing the individual iterators.
The tuple of iterators is now implemented in terms of a Boost fusion sequence.
Because of this the 'tuple' may be any Boost fusion sequence and, for backwards
compatibility through a Boost fusion sequence adapter, a Boost tuple. Because the
'tuple' may be any boost::fusion sequence the 'tuple' may also be any type for which a
Boost fusion adapter exists. This includes, among others, a std::tuple and a std::pair.
Just remember to include the appropriate Boost fusion adapter header files for these
other Boost fusion adapters. The zip_iterator header file already includes the
Boost fusion adapter header file for Boost tuple, so you need not include it yourself
to use a Boost tuple as your 'tuple'.
