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

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

IllegalStateException - if no suitable persistence units can be resolved

resolvePersistenceContext

@Deprecated
javax.persistence.EntityManager resolvePersistenceContext(javax.enterprise.inject.spi.InjectionPoint injectionPoint)

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.

Resolve the value for the given @PersistenceContext injection point

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

resolvePersistenceUnit

@Deprecated
javax.persistence.EntityManagerFactory resolvePersistenceUnit(javax.enterprise.inject.spi.InjectionPoint injectionPoint)

Deprecated. Instead of calling this method at runtime, Weld should register every persistence unit injection point at bootstrap using registerPersistenceUnitInjectionPoint(InjectionPoint) and use the returned factory for producing injectable instances at runtime.

Resolve the value for the given @PersistenceUnit injection point

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
