| 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 /> |
