Detailed Description

Gateway side of RC-MAC.

This MAC protocol assumes a network topology where all traffic is destined for a set of GW nodes which are connected via some out of band (RF?) means. UanMacRcGw is the protocol which runs on the gateway nodes.

This particular implementation assumes that there is only a single gateway.

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.
