public interface JpaInjectionServices extends Service {

    
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.

Parameters:
injectionPoint the injection point metadata
Returns:
factory for obtaining EntityManager instances
Throws:
IllegalArgumentException if the injection point is not annotated with
IllegalStateException if no suitable persistence units can be resolved
PersistenceContext:
if the injection point is a method that doesn't follow JavaBean conventions or if the injection
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.

Parameters:
injectionPoint the injection point metadata
Returns:
factory for obtaining EntityManagerFactory instances
Throws:
IllegalArgumentException if the injection point is not annotated with
IllegalStateException if no suitable persistence units can be resolved
PersistenceUnit:
or, if the injection point is a method that doesn't follow JavaBean conventions
    ResourceReferenceFactory<EntityManagerFactory> registerPersistenceUnitInjectionPoint(InjectionPoint injectionPoint);

    
Resolve the value for the given

Deprecated:
Instead of calling this method at runtime, Weld should register every persistence context injection point at bootstrap using registerPersistenceContextInjectionPoint(InjectionPoint) and use the returned factory for producing injectable instances at runtime.
Parameters:
injectionPoint the injection point metadata
Returns:
an instance of the entity manager
Throws:
IllegalArgumentException if the injection point is not annotated with
IllegalStateException if no suitable persistence units can be resolved for injection
PersistenceContext:
injection point
PersistenceContext:
or, if the injection point is a method that doesn't follow JavaBean conventions
    @Deprecated
    EntityManager resolvePersistenceContext(InjectionPoint injectionPoint);
