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 Range	`T&`
`CList<T,A>`	Bidirectional Range	`T&`
`CMap<K,AK,M,AM>`	Forward Range	`Range::CPair&`
`CTypedPtrArray<B,T*>`	Random Access Range	`T* const`
`CTypedPtrList<B,T*>`	Bidirectional Range	`T* const`
`CTypedPtrMap<B,T,V>`	Forward Range	`std::pair<T,V> const`
`CByteArray`	Random Access Range	`BYTE&`
`CDWordArray`	Random Access Range	`DWORD&`
`CObArray`	Random Access Range	`CObject*&`
`CPtrArray`	Random Access Range	`void*&`
`CStringArray`	Random Access Range	`CString&`
`CUIntArray`	Random Access Range	`UINT&`
`CWordArray`	Random Access Range	`WORD&`
`CObList`	Bidirectional Range	`CObject*&`
`CPtrList`	Bidirectional Range	`void*&`
`CStringList`	Bidirectional Range	`CString&`
`CMapPtrToWord`	Forward Range	`std::pair<void*,WORD> const`
`CMapPtrToPtr`	Forward Range	`std::pair<void,void> const`
`CMapStringToOb`	Forward Range	`std::pair<String,CObject*> const`
`CMapStringToString`	Forward Range	`Range::CPair&`
`CMapWordToOb`	Forward Range	`std::pair<WORD,CObject*> const`
`CMapWordToPtr`	Forward Range	`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 below.

Adam Walling has provided the header <boost/range/mfc_map.hpp> to add support for the map adaptor with MFC map types.
