Description
Increments the reference count for the interfaced object's interface.
_AddRef implements the IInterface method, _AddRef, which increments the reference count of an interface and returns the current reference count.
If the interfaced persistent object has an Owner and that owner supports an interface, then _AddRef simply calls the _AddRef method of the Owner. Otherwise, it simply returns –1.
