Method Detail

registerPersistenceContextInjectionPoint

ResourceReferenceFactory<javax.persistence.EntityManager> registerPersistenceContextInjectionPoint(javax.enterprise.inject.spi.InjectionPoint injectionPoint)

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 PersistenceContext, if the injection point is a method that doesn't follow JavaBean conventions or if the injection

IllegalStateException - if no suitable persistence units can be resolved

registerPersistenceUnitInjectionPoint

ResourceReferenceFactory<javax.persistence.EntityManagerFactory> registerPersistenceUnitInjectionPoint(javax.enterprise.inject.spi.InjectionPoint injectionPoint)

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 PersistenceUnit, or, if the injection point is a method that doesn't follow JavaBean conventions

IllegalStateException - if no suitable persistence units can be resolved
