EE4J 10.0.0 · jakarta.enterprise.inject.spi.ProcessProducer

The container fires an event of this type for each producer method or field of each enabled bean, including resources.

Any observer of this event is permitted to wrap and/or replace the Producer by calling either setProducer(Producer) or configureProducer(). If both methods are called within an observer notification an IllegalStateException is thrown. The container must use the final value of this property, after all observers have been called, whenever it calls the producer or disposer.

For example, this observer decorates the Producer for the all producer methods and field of type EntityManager.

void decorateEntityManager(@Observes ProcessProducer<?, EntityManager> pp) {
    pit.setProducer(decorate(pp.getProducer()));
}

If any observer method of a ProcessProducer event throws an exception, the exception is treated as a definition error by the container.

CDI Lite implementations are not required to provide support for Portable Extensions.

Method Summary

Modifier and Type	Method and Description
public void	addDefinitionError(Throwable The definition error to register as a `java.lang.Throwable` t) Registers a definition error with the container, causing the container to abort deployment after bean discovery is complete.
public ProducerConfigurator<X>	Returns: a non reusable `ProducerConfigurator` to configure the original `Producer`. configureProducer() Returns a `ProducerConfigurator` initialized with the `Producer` processed by this event, to configure a new `Producer` that will replace the original one at the end of the observer invocation.
public AnnotatedMember<T>	Returns: the `AnnotatedMember` representing the producer getAnnotatedMember() Returns the `AnnotatedField` representing the producer field or the `AnnotatedMethod` representing the producer method.
public Producer<X>	Returns: the `Producer` invoker object used by the container getProducer() Returns the `Producer` object that will be used by the container to call the producer method or read the producer field.
public void	setProducer(Producer<X> the new `Producer` object to use producer) Replaces the `Producer` object that will be used by the container to call the producer method or read the producer field.
