FILE:
ProtocolNotification.cpp
DESCRIPTION:
Implementation of cProtocolNotification base class and derivations
PUBLIC CLASSES AND METHODS:
sProtocolNotificationEvent
Generic protocol event notification structure
cProtocolNotification
This abstract base class provides notification of protocol server
events sent from the protocol server to protocol server clients
cProtocolQueueNotification
This class provides notification via a cSyncQueue object
populated with sProtocolNotificationEvent objects
