========
Overview
========

Boost.Range MFC/ATL Extension provides `Boost.Range`_ support for MFC/ATL collection and string types.

==========
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.

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``,

============
const Ranges
============

``range_reference<const Range>::type`` is defined by the following algorithm.
Let ``Range`` be any type listed above and ``ReF`` be the same as ``range_reference<Range>::type``.


.. parsed-literal::

    if (Range is CObArray || Range is CObList)
        return CObject const \* &
    else if (Range is CPtrArray || Range is CPtrList)
        return void const \* &
    else if (there is a type X such that X& is the same as ReF)
        return X const &
    else if (there is a type X such that X* const is the same as ReF)
        return X const \* const
    else
        return ReF


Other `Boost.Range`_ metafunctions are defined by the following.
``range_value<const Range>::type`` is the same as ``range_value<Range>::type``,
``range_difference<const Range>::type`` is the same as ``std::ptrdiff_t``, and
``range_pointer<const Range>::type`` is the same as ``add_pointer<remove_reference<range_reference<const Range>::type>::type>::type``.
