CMapWordToPtr Class

Supports maps of void pointers keyed by 16-bit words.

class CMapWordToPtr : public CObject

The member functions of CMapWordToPtr 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 a pointer to void. Wherever you see a CString or a const pointer to char as a function parameter or return value, substitute WORD.

BOOL CMapStringToOb::Lookup( const char* <key>,

CObject*& <rValue> ) const;

for example, translates to

BOOL CMapWordToPtr::Lookup( WORD <key>, void*& <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.

Word-to-pointer maps may not be serialized.

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