UUID value generator. Type 1 generator is based on the time-based generator | |
in the Apache Commons Id project: http://jakarta.apache.org/commons/sandbox | |
/id/uuid.html The type 4 generator uses the standard Java UUID generator. | |
The type 1 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:<br /> | |
