can a subclass method determine if called by superclass?

Thanks Ian - that is one possibility.

I am trying to create a subclass with slightly different functionality
and use it with an existing code base i.e. there is already one or
more modules that instantiate the current superclass and I want to
just drop in this new class to replace it with no ripples up the line
(so to speak). The new class implements some interface changes that
can safely be hidden from the rest of the application.
