java.lang.Object

au.com.cybersearch2.classyjpa.entity.PersistenceContainer

public class PersistenceContainer
extends Object

PersistenceContainer Provides task-scoped persistence context with automatic rollback if a fatal exception occurs. The unit of work is passed as a PersistenceWork object which handles one of 3 outcomes: success, failure and rollback. Failure is intended for when pre-conditions are not satisfied. If failure occurs after changes have be made, then rollback should be invoked.
