Class PayloadUUID

java.lang.Object

org.jgroups.util.UUID

org.jgroups.util.PayloadUUID

All Implemented Interfaces:

Externalizable, Serializable, 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.
