Examples of EventRegistration

Event registration is the type returned from registering a single event, or from registering an event handler. Since an event handler is comprised of single events, the handler contains a list of children which are themselves event handlers.

net.jini.core.event.EventRegistration

A utility class for use as a return value for event-interest registration methods. Objects of this class are meant to encapsulate the information needed by a client to identify a notification as a response to a registration request and to maintain that registration request. It is not mandatory for an event-interest registration method to use this class.

A registration of interest in some kind of event that occurs within the scope of a transaction is leased in the same way as other event interest registrations. However, the duration of the registration is the minimum of the length of the lease and the duration of the transaction. Simply put, when the transaction ends (either because of a commit or an abort) the interest registration also ends. This is true even if the lease for the event registration has not expired and no call has been made to cancel the lease. @author Sun Microsystems, Inc. @since 1.0
