Event Notification Service

File: DevGuideExamples/NotifyService/Filtering/README

This example extends the NotifyService/Messenger example by
demonstrating how filtering can be incorporated into the utilization
of the Notification channel.  Supplier-side, and consumer-side
filtering can be implemented, but only consumer_side filtering is
demonstrated in this example.

Filters are configured to guarantee that only certain events are
passed to the consumer. The criteria is specified by imposing constraints
on the appropriate fields of a structured event.


The Client code is stored in:

DevGuideExamples/NotifyService/Filtering/MessengerClient.cpp

The Server code is stored in:

DevGuideExamples/NotifyService/Filtering/MessengerServer.cpp

The Consumer code is stored in:

DevGuideExamples/NotifyService/Filtering/MessengerConsumer.cpp
