- // TAO_Connection_Handler
- //
- // = DESCRIPTION
- // This class is an abstraction for the connection handlers. The
- // connections handler in every protocol can derive from this
- // class as well as the ACE_Svc_Handler specialised for the
- // right protocol. This way, most of the common code for the
- // different protocls would be in this implementation. Further,
- // this class wold be of immense use in storing the handlers in
- // the Cache for TAO. This would help in purging entries which
- // is generally accompanied by closing the open handles and
- // deleting memory associated with the handlers.
-
- // Note: This class has NOT abstracted the GIOP specific
- // details. It is just to be safe so that, we can reuse this
- // class for any messaging protocol underneath. This way we need
- // not touch the Cache setup even when using other protocols (I
- // mean messaging). BUT, I doubt whether this abstraction will
- // satisfy the needs of other messaging protocols. (will not?).
