public class EventRegistration extends Object implements Serializable
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.
