Event Notification Service
File: examples/NotifyService/Messenger/README
This directory contains a simple example of using the Notification Service.
This example extends the Messenger example in GettingStarted directory
to illustrate how the Notification channel can be used to push messages
from the supplier to the consumer. Structured events are used to demonstrate
the operation of the channel. The example uses the push/push model.
The MessengerServer in this example plays the role of a server for
the MessengerClient and the role of a supplier for the MessengerConsumer.
The flow of messages is shown below:
MessengerClient->MessengerSupplier->NotificationChannel->MessengerConsumer.
The Client code is stored in:
examples/NotifyService/Messenger/MessengerClient.cpp
The Server code is stored in:
examples/NotifyService/Messenger/MessengerServer.cpp
The Consumer code is stored in:
examples/NotifyService/Messenger/MessengerConsumer.cpp
