Class UUID

  org.eclipse.ohf.ihe.xds.source.utils.UUID

public class UUID
extends java.lang.Object

Generates a (mostly) ASN.1 complaint UUID.
Under Windows the MAC address of the machine is used, under Linux and other OS's a randomly generated construct using the SHA-1 message digest is used. It is thus possible that UUIDs will not be completely unique under non Windows platforms, but given the number of bits of random data used to generate the fake MAC addresses for non Windows machines, it is very unlikely any collosions will every occur in practice.
