CMapPtrToWord

The CMapPtrToWord class supports maps of 16-bit words keyed by void pointers.

The member functions of CMapPtrToWord are similar to the member functions of class CMapStringToOb. Because of this similarity, you can use the CMapStringToOb reference documentation for member function specifics. Wherever you see a CObject pointer as a function parameter or return value, substitute WORD. Wherever you see a CString or a const pointer to char as a function parameter or return value, substitute a pointer to void.

BOOL CMapStringToOb::Lookup( const char* <key>,
                             CObject*& <rValue> ) const;

for example, translates to

BOOL CMapPtrToWord::Lookup( const void* <key>, WORD& <rValue> ) const;

CMapWordToPtr incorporates the IMPLEMENT_DYNAMIC macro to support run-time type access and dumping to a CDumpContext object. If you need a dump of individual map elements, you must set the depth of the dump context to 1 or greater.

Pointer-to-word maps may not be serialized.

When a CMapPtrToWord object is deleted, or when its elements are removed, the pointers and the words are removed. The entities referenced by the key pointers are not removed.
