template< class BASE_CLASS, class KEY, class VALUE >
class CTypedPtrMap : public BASE_CLASS

Parameters

  • BASE_CLASS
    Base class of the typed pointer map class; must be a pointer map class (CMapPtrToPtr, CMapPtrToWord, CMapWordToPtr, or CMapStringToPtr).

Remarks

When you use CTypedPtrMap, the C++ type-checking facility helps eliminate errors caused by mismatched pointer types.

Because all CTypedPtrMap functions are inline, use of this template does not significantly affect the size or speed of your code.
