Class EventSequenceID

java.lang.Object

org.apache.geode.cache.wan.EventSequenceID

public final class EventSequenceID
extends java.lang.Object

This class wraps 1) DistributedMembershipID 2) ThreadID 3) SequenceID attributes which are used to uniquely identify any Region Operation like create, update, destroy etc. This helps in sequencing the events belonging to a unique producer. As an example, the EventSequenceID can be used to track the events received by AsyncEventListener. If the event has already been seen, AsyncEventListener can choose to ignore it.
