oracle.ide.util.GuidGen
public class GuidGen
This static class provided utilties for generation and manipulation of DFC style Globally Unique Identifiers, using the original HP/OSF UUID reference implemenation as a basis. Since the Java runtime does not allow access to the full IEEE 802 48-bit ethernet address of a host (if indeed there is one) this implementation attempts to use the 32-bit IP number in the first instance, and defaults to the sample pseudo-unique algorithm if the IP address is not available.
A native method-based extension will be provided in due course to provide true GUID values.
