TAO_DynEnum_i * TAO_DynEnum_i::_narrow ( CORBA::Object_ptr obj ) [static]

Todo:: Narrowing a LocalObject to a CORBA::Object is broken right now. The solution seems to be making CORBA::Object an abstract base class and create a CORBA::RemoteObject for regular object. Or, even easier, add a is_local member into CORBA::Object. I'll take the easier route for now.

Reimplemented from CORBA::LocalObject.
