Examples of IdentifierFactory

org.datanucleus.store.mapped.IdentifierFactory
Factory that creates immutable instances of DatastoreIdentifier. Identifiers are of a particular type. Each datastore could invent its own particular types as required, just that the ones here should be the principal types required.
