Returns:

whether possibleDuplicate is set for this event

getEventSequenceID

EventSequenceID getEventSequenceID()

Returns the wrapper over the DistributedMembershipID, ThreadID, SequenceID which are used to uniquely identify any region operation like create, update etc. This helps in sequencing the events belonging to a unique producer. e.g. The EventID can be used to track events received by AsyncEventListener to avoid processing duplicates.

Returns:

the wrapper over the DistributedMembershipID, ThreadID, SequenceID which are used to uniquely identify any region operation
