Examples of BasicEventConsumer

org.rioproject.impl.event.BasicEventConsumer
The BasicEventConsumer is a helper class that manages the discovery of {@link org.rioproject.event.EventProducer} instances that provide support foruser defined events. The BasicEventConsumer is to be used as a local (within a JVM) utility, managing the discovery, event registration and leasing of {@link net.jini.core.event.EventRegistration} objects on behalf ofclient(s). In this manner, clients wishing to easily register (subscribe) for the notification of an event in the distributed system need not be overly concerned with the underlying semantics and management of event registrations, leases and events. @author Dennis Reedy
