org.jgroups.util.UUID

org.jgroups.util.AdditionalDataUUID

All Implemented Interfaces:

Externalizable, Serializable, Cloneable, Comparable<Address>, Address, Streamable

public class AdditionalDataUUID
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.
