Interface ARMEvent

All Superinterfaces:

java.io.Externalizable, java.io.Serializable

All Known Implementing Classes:

ReplicaFailureEvent, ReplicaPingEvent

public interface ARMEvent
extends java.io.Externalizable

Event types implementing the ARMEvent interface may be passed to the replication manager to notify it of certain events. The event itself must provide the handle() method, enabling the replication manager to invoke the event handler. That is, events provide self-handling.

Note that events must also implement the Externalizable interface.

Since:

Jgroup 1.2
