Remarks
CanExtend returns whether an extender is available for the given CATID and name for the specified Extendee instance. The extender provider may need to inspect the extendee instance to determine whether or not it should provide an Extender for it. For example, an extender provider may be chartered to create an "ATLClass" extender to a class object, but only if Class.Language has a value of "C++." The extender provider is expected to do this kind of check in this CanExtend method.
Note
The extendee object is passed as an IUnknown interface.
