Notification Service examples: This directory has examples to illustrate how to use the Notification Service Examples: Filter: A simple example to how how to do filtering of events. ------ An event passing through the channel encounters filters at the proxy, admin and channel level.This example shows how to setup filters and use them. Subscribe: A simple example to show how to specify subscription constraints. --------- This example does not add any filters to keep the example simple. If filters are added, then they would be evaluated *after* the event type constraints have been met. Thus subscriptions are a way of provide coarse grain filtering.
