Class EOTemporaryGlobalID

java.lang.Object
  net.wotonomy.control.EOGlobalID
      net.wotonomy.control.EOTemporaryGlobalID

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class EOTemporaryGlobalID
extends EOGlobalID

EOTemporaryGlobalID is a network-wide unique key. This is used by EOEditingContext to construct temporary ids when new objects are created.

The specified format of the key is a byte array: < Sequence [2], ProcessID [2], Time [4], IP Addr [4] >, but because java does not allow access to the process id, the timestamp of when this class is first loaded is used to simulate a process id.
