Re: [cdi-dev] WithAnnotations with ProcessInjectionTarget events

Hi Nigel, Check the error message, I think it's not the same method you referenced it. However I would like to see @WithAnnotations or a similar solution for other Process* types. Best Regards, George Gastaldi Em 14/08/2015 09:04, "Nigel Deakin" <nigel.deakin(a)oracle.com <mailto:nigel.deakin@oracle.com>> escreveu: I'm writing a portable extension, and my Extension class includes the following observer method public <X> void processInjectionTarget( @Observes ProcessInjectionTarget<X> event) { When I start the server (Glassfish) I see this warning in the log: WELD-000411: Observer method [BackedAnnotatedMethod] public com.foo.MyExtension.processAnnotatedType(@Observes ProcessAnnotatedType<Object>) receives events for all annotated types. Consider restricting events using @WithAnnotations or a generic type with bounds.]] I thought "OK, fair enough. I only want to receive ProcessInjectionTarget events for classes that have a specific annotation. So I'll do what it suggests and @WithAnnotations to restrict the events received." However if I look up the javadocs for WithAnnotations it says "WithAnnotations may be applied to any portable extension observer method with an event parameter type of ProcessAnnotatedType to filter the events delivered." And if I try using WithAnnotations on the above method, I indeed get an error at runtime. So the warning message WELD-000411 is incorrect, since it suggests doing something that is not allowed. @WithAnnotations would have been perfect for my needs. Why is it not allowed when observing ProcessInjectionTarget events? So it looks as if I will simply have to receive every such event and check whether it has the required annotation: public <X> void processInjectionTarget( @Observes ProcessInjectionTarget<X> event) { if (!event.getAnnotatedType().isAnnotationPresent(MyAnnotation.class)) { return; } This doesn't look very efficient to me, since there will be a lot of irrelevant events. Is there a better way?
