Examples of org.apache.derby.catalog.UUID

org.apache.derby.catalog.UUID
An interface for accessing Cloudscape UUIDs, unique identifiers.
The values in the system catalog held in ID columns with a type of CHAR(36) are the string representations of these UUIDs.
A UUID implements equals() and hashCode based on value equality.
