org.apache.derby.iapi.sql.depend.Provider
A provider is an object that others can build dependencies on. Providers can themselves also be dependents and thus be invalid/revalidated in turn. Revalidating a provider may, as a side-effect, re-validate its dependents -- it is up to the implementation to determine the appropriate action.

                UUID                        providerID = pi.getObjectId();
                Provider                    provider = (Provider) finder.getDependable( dd, providerID );


                dm.addDependency( defDesc, provider, cm );
