Class ErrorNotification

java.lang.Object
  com.continuent.tungsten.fsm.core.Event
      com.continuent.tungsten.replicator.ErrorNotification

All Implemented Interfaces:

com.continuent.tungsten.fsm.event.CriticalEvent, com.continuent.tungsten.fsm.event.OutOfBandEvent

public class ErrorNotification
extends com.continuent.tungsten.fsm.core.Event
implements com.continuent.tungsten.fsm.event.OutOfBandEvent, com.continuent.tungsten.fsm.event.CriticalEvent

This class defines a ErrorNotification, which denotes a severe replication error that causes replication to fail. It implements the OutOfBandEvent interface to ensure it is processed out-of-band no matter how it is submitted to the state machine. It also implements critical event so that event processing is not interrupted, which prevents race conditions around shutdown.
