CTypedPtrMap Class

Provides a type-safe "wrapper" for objects of the pointer-map classes CMapPtrToPtr, CMapPtrToWord, CMapWordToPtr, and CMapStringToPtr.

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).

  • KEY
    Class of the object used as the key to the map.

  • VALUE
    Class of the object stored in the map.

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.

For more information on using CTypedPtrMap, see the articles Collections and Template-Based Classes.
