Hi Everyone,

I'm looking for a little OO guidance here ...

If I weren't using CORBA, my design would show two classes both decended
from a common abstract-class ancestor.  The pure-virtual methods that would
be implemented by the decendents would be public.  The methods implemented
by the ancestor would be protected.

Here's my difficulty.  I would like to have only the public methods appear
as IDL interfaces.   How do I declare in IDL or otherwise the relationship
of the decendent class to their ancestor?  In IDL I tried declaring
(overloading) in the decendent an ancestor's method -- this generated an IDL
compilation error.  If I copy the method definitions to each decendent and
not even have an interface for the ancestor, where do I tie the
IDL-generated class back to the ancestor?
