public class ClusterIdFactory
extends java.lang.Object
The aim of this class is to generate unique IDs to identify an instance of a
clustered server. The IDs generated by this class are guaranteed to be
unique on the whole network. Several methods may be provided.
To generate an ID, time may be needed, because they can be generated by
locking a well know resource for a period of time.
