org.apache.derby.iapi.services.uuid
Interface UUIDFactory  

---

public interface UUIDFactory

Generates and recreates unique identifiers. An example of such an identifier is:

        E4900B90-DA0E-11d0-BAFE-0060973F0942
  

These resemble DCE UUIDs, but use a different implementation.

The string format is designed to be the same as the string format produced by Microsoft's UUIDGEN program, although at present the bit fields are probably not the same.
