Method Detail

delegate

protected abstract JpaInjectionServices delegate()

registerPersistenceContextInjectionPoint

public ResourceReferenceFactory<EntityManager> registerPersistenceContextInjectionPoint(InjectionPoint injectionPoint)

Description copied from interface: JpaInjectionServices

Register a persistence context injection point. The implementation validates the injection point. If the validation passes, an instance of ResourceReferenceFactory is returned which may be used at runtime for creating instances of the resource.

Specified by:

registerPersistenceContextInjectionPoint in interface JpaInjectionServices

Parameters:

injectionPoint - the injection point metadata

Returns:

factory for obtaining EntityManager instances

registerPersistenceUnitInjectionPoint

public ResourceReferenceFactory<EntityManagerFactory> registerPersistenceUnitInjectionPoint(InjectionPoint injectionPoint)

Description copied from interface: JpaInjectionServices

Register a persistence unit injection point. The implementation validates the injection point. If the validation passes, an instance of ResourceReferenceFactory is returned which may be used at runtime for creating instances of the resource.

Specified by:

registerPersistenceUnitInjectionPoint in interface JpaInjectionServices

Parameters:

injectionPoint - the injection point metadata

Returns:

factory for obtaining EntityManagerFactory instances

resolvePersistenceContext

public EntityManager resolvePersistenceContext(InjectionPoint injectionPoint)

Description copied from interface: JpaInjectionServices

Resolve the value for the given PersistenceContext injection point

Specified by:

resolvePersistenceContext in interface JpaInjectionServices

Parameters:

injectionPoint - the injection point metadata

Returns:

an instance of the entity manager

resolvePersistenceUnit

public EntityManagerFactory resolvePersistenceUnit(InjectionPoint injectionPoint)

Description copied from interface: JpaInjectionServices

Resolve the value for the given PersistenceUnit injection point

Specified by:

resolvePersistenceUnit in interface JpaInjectionServices

Parameters:

injectionPoint - the injection point metadata

Returns:

an instance of the entity manager
