Package org.jgroups.util

Class FlagsUUID

java.lang.Object

org.jgroups.util.UUID

org.jgroups.util.FlagsUUID

All Implemented Interfaces:

java.lang.Comparable<Address>, Address, Constructable<UUID>, SizeStreamable, Streamable

Direct Known Subclasses:

ExtendedUUID

public class FlagsUUID
extends UUID

Subclass of UUID accommodating additional data such as a flag. There may be many instances in memory, and as they are serialized a lot and sent across the wire, I tried to make this as compact as possible.

Since:

3.5
