Detailed Description

Non-gateway node MAC for reservation channel MAC protocol.

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

void ns3::UanMacRc::DoDispose ( void )

protectedvirtual

Destructor implementation.

This method is called by 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.
