Package javax.enterprise.inject.spi
Interface ProcessProducer<T,X>
- Type Parameters:
T
- The bean class of the bean that declares the producer method or fieldX
- The return type of the producer method or the type of the producer field
public interface ProcessProducer<T,X>
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
. 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.
