Overview
========
Boost.Range MFC/ATL Extension provides `Boost.Range`_ support for MFC/ATL collection and string types.
.. parsed-literal::
CTypedPtrArray<CPtrArray, CList<CString> \*> myArray;
...
BOOST_FOREACH (CList<CString> \*theList, myArray)
{
BOOST_FOREACH (CString& str, \*theList)
{
boost::to_upper(str);
std::sort(boost::begin(str), boost::end(str));
...
}
}

* `MFC Ranges`_
* `ATL Ranges`_

Requirements
============
- `Boost C++ Libraries Version 1.34.0`__ or later (no compilation required)
- Visual C++ 7.1 or Visual C++ 8.0
__ Boost_
==========
MFC Ranges
==========
If the ``<boost/range/mfc.hpp>`` is included before or after `Boost.Range`_ headers,
the MFC collections and strings become models of Range.
The table below lists the Traversal Category and ``range_reference`` of MFC ranges.
============================= ================== =======================================
``Range`` Traversal Category ``range_reference<Range>::type``
============================= ================== =======================================
``CArray<T,A>`` Random Access ``T&``

----------------------------- ------------------ ---------------------------------------
``CTypedPtrMap<B,T*,V*>`` Forward ``std::pair<T*,V*> const``
----------------------------- ------------------ ---------------------------------------
``CByteArray`` Random Access ``BYTE&``

----------------------------- ------------------ ---------------------------------------
``CMapWordToPtr`` Forward ``std::pair<WORD,void*> const``
============================= ================== =======================================
Other `Boost.Range`_ metafunctions are defined by the following.
Let ``Range`` be any type listed above and ``ReF`` be the same as ``range_reference<Range>::type``.
``range_value<Range>::type`` is the same as ``remove_reference<remove_const<Ref>::type>::type``,
``range_difference<Range>::type`` is the same as ``std::ptrdiff_t``, and
``range_pointer<Range>::type`` is the same as ``add_pointer<remove_reference<Ref>::type>::type``.
As for ``const Range``, see `const Ranges`_.

ATL Ranges
==========
If the ``<boost/range/atl.hpp>`` is included before or after `Boost.Range`_ headers,
the ATL collections and strings become models of Range.
The table below lists the Traversal Category and ``range_reference`` of ATL ranges.

If the template argument is not a model of Forward Traversal Iterator, one can
still use a subset of the interface. In particular, <code>size()</code> requires
Forward Traversal Iterators whereas <code>empty()</code> only requires Single
Random Access Iterators whereas <code>empty()</code> only requires Single
Pass Iterators.

Recall that many default constructed iterators
are <i>singular</i> and hence can only be assigned, but not compared or
incremented or anything. However, if one creates a default constructed
<code>iterator_range</code>, then one
can still call all its member functions. This means that the
<code>iterator_range</code> will still be usable in many contexts even
though the iterators underneath are not.
