Tests this object's relationship to a given class.
BOOL IsKindOf(
const CRuntimeClass* pClass
) const;
Parameters
- pClass
A pointer to a CRuntimeClass structure associated with your CObject-derived class.
Return Value
Nonzero if the object corresponds to the class; otherwise 0.
Remarks
This function tests pClass to see if (1) it is an object of the specified class or (2) it is an object of a class derived from the specified class. This function works only for classes declared with the DECLARE_DYNAMIC, DECLARE_DYNCREATE, or DECLARE_SERIAL macro.
Do not use this function extensively because it defeats the C++ polymorphism feature. Use virtual functions instead.
Example
See CObList::CObList for a listing of the CAge class used in all CObject examples.
CAge a(21); // Must use IMPLEMENT_DYNAMIC, IMPLEMENT _DYNCREATE, or
// IMPLEMENT_SERIAL
ASSERT(a.IsKindOf(RUNTIME_CLASS(CAge)));
ASSERT(a.IsKindOf(RUNTIME_CLASS(CObject)));
