Interface SequenceFactory

All Superinterfaces:

Serializable

All Known Implementing Classes:

DBSequenceFactory, TrueSequenceFactory, ClassSequenceFactory

public interface SequenceFactory

extends Serializable

An implementation of the SequenceFactory interface is used to generate unique primary key values for newly persisted JDO instances. SequenceFactories must be serializable so that the PersistenceManagerFactory can retain them when stored in JNDI.

Method Summary

long	getNext(Class cls, Connector connector) Return a unique primary key value for the given class.
void	setConfiguration(JDBCConfiguration conf, DBDictionary dict) Set the configuration for this factory; allows access to database connection information, etc.
