Updated EntityManager / Query APIs
JPA 2.0 Root | Enhancement Request
Issue Summary
In JPA 2.0 the specification extends EntityManager and Query APIs. New APIs have been added for getting supported properties and getting the owning Entity Manager Factory.
A new operation 'clear' was also added including a new Cascade Type. Calling clear on an Entity allows the user to remove an Entity and cascaded related entities from the persistence context. Effectively an unregister call.
The new Locking APIs will be covered by the locking functionality feature (http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/pessimistic_locking) but as Query Hints can now be provided to lock, find and refresh calls this feature must add support for EM processing of these Query Hints.
See JPA 2.0 ED section 3.1.1 and 3.2.6 for details.
General Solution
The implementation of this functionality should be straight forward.
Work Required
- Develop test for testing new non-pessimistic locking APIs
- approx 2 days
- Update Processing to
- approx 3 days - clear(Object entity)
- approx 2 days - remaining APIs
