[cdi-dev] Easy way to get 'original' type from alternative producers

Hi, When writing an alternative producer, e.g. @Alternative @Priority(500) @ApplicationScoped public class ApplicationInit { @Produces public HttpAuthenticationMechanism produce(BeanManager beanManager) { return ... } } You not rarely need the bean the producer is going to be an alternative for. For instance to wrap it, or otherwise augment it, or perhaps to take a few values from. In order to get that bean, a bunch of quite verbose code is needed. I.e I came up with: HttpAuthenticationMechanism mechanism = createRef( beanManager.resolve( beanManager.getBeans(HttpAuthenticationMechanism.class) .stream() .filter(e -> !e.getBeanClass().equals(ApplicationInit.class)) .collect(toSet())), beanManager); And: HttpAuthenticationMechanism createRef(Bean<?> bean, BeanManager beanManager) { return (HttpAuthenticationMechanism) beanManager.getReference( bean, HttpAuthenticationMechanism.class, beanManager.createCreationalContext(bean)); } I wonder if it would not be a good idea to introduce something to get that original bean more easily, i.e. just like a decorator and @Delegate. E.g. @Alternative @Priority(500) @ApplicationScoped public class ApplicationInit { @Produces public HttpAuthenticationMechanism produce(BeanManager beanManager, HttpAuthenticationMechanism original) { return ... } } Or reuse the @Delegate (perhaps with the @Alternative annotation) @Alternative @Priority(500) @ApplicationScoped public class ApplicationInit { @Inject @Delegate @Alternative (?) private HttpAuthenticationMechanism original; @Produces public HttpAuthenticationMechanism produce(BeanManager beanManager) { return ... } } Thoughts?
