Examples of EventBroker

org.wso2.carbon.event.core.EventBroker
the main eventing interface for the other components. this interface supports two kinds of subscriptions. 1. subscritions with EventDispatcher Event broker does not persists these subscriptions and call the on message method upon receiving an event. 2. subscriptions with EventDispatcherName Event broker persists these subscriptions. It is responsibility of the user who calls this method to register the eventDispatcher with the given name. In a server restart again caller has to register the Event dispatcher.
