CMapPtrToPtr Class
Supports maps of void pointers keyed by void pointers.
class CMapPtrToPtr : public CObject
Заметки
The member functions of CMapPtrToPtr 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 a pointer to void.
BOOL CMapStringToOb::Lookup( const char* <key>,
CObject*& <rValue> ) const;
for example, translates to
BOOL CMapPtrToPtr::Lookup( void* <key>, void*& <rValue> ) const;
CMapPtrToPtr 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 (pointer values), you must set the depth of the dump context to 1 or greater.
Pointer-to-pointer maps may not be serialized.
When a CMapPtrToPtr object is deleted, or when its elements are removed, only the pointers are removed, not the entities they reference.
