POID - Persistent Id Generation. This package provides a series of classes providing generation of identities. The entry point is PoidManager which is used for creating and managing the various PoidGenerators. All generators are known by a symbolic name and can be accessed from the PoidManager via that name once created. All PoidGenerators implements the standard JDO2 "javax.jdo.datastore.Sequence" interface providing a standard interface to access identity values.
