Package org.jgroups.stack

Class IpAddressUUID

java.lang.Object

org.jgroups.stack.IpAddress

org.jgroups.stack.IpAddressUUID

All Implemented Interfaces:

java.lang.Comparable<Address>, Address, Constructable<IpAddress>, PhysicalAddress, SizeStreamable, Streamable

public class IpAddressUUID
extends IpAddress

IpAddress with a 'semi'-UUID to prevent reincarnation when the port is fixed. The randomness is given through a long and an int. On 64-bit architectures, this increases the memory size from 24 to 32 bytes per instance.

See https://issues.jboss.org/browse/JGRP-2080 for details
