public class Guid

extends java.lang.Object

This class is capable of generated what is very close to a globally unique ID. This adheres to no specification because we can't get access to the IEEE hardware address for the machine (otherwise we might adhere to the Network Working Group GUID standard created by Paul J. Leach, Microsoft, and Rich Salz).
