Examples of ReplicationMsg

org.nasutekds.server.replication.protocol.ReplicationMsg
Abstract class that must be used when defining messages that can be sent for replication purpose between servers. When extending this class one should also create a new MSG_TYPE and should update the generateMsg() method.
