Class PayloadUUID

java.lang.Object
  extended by org.jgroups.util.UUID
      extended by org.jgroups.util.PayloadUUID
All Implemented Interfaces:
java.io.Externalizable, java.io.Serializable, java.lang.Comparable<Address>, Address, Streamable

public class PayloadUUID
extends UUID

Subclass of UUID which adds a string as payload. An instance of this can be fed to JChannel.setAddressGenerator(org.jgroups.stack.AddressGenerator), with the address generator creating PayloadUUIDs.
