java.lang.Objectorg.apache.openjpa.lib.util.UUIDGenerator
public class UUIDGenerator
UUID value generator. Based on the time-based generator in the Apache
Commons Id project: http://jakarta.apache.org/commons/sandbox/id/uuid.html
The code has been vastly simplified and modified to replace the ethernet
address of the host machine with the IP, since we do not want to require
native libs and Java cannot access the MAC address directly.
In spirit, implements the IETF UUID draft specification, found here:
