[cdi-dev] [JBoss JIRA] (CDI-271) Provide a way to inject Event metadata into an observer method

Provide a way to inject Event metadata into an observer method -------------------------------------------------------------- Key: CDI-271 URL: https://issues.jboss.org/browse/CDI-271 Project: CDI Specification Issues Issue Type: Feature Request Components: Events Reporter: Arne Limburg Currently there is no way for observer methods to access the qualifiers of the fired event (i.e. to access @Nonbinding members). Consider the following example: {code} @Inject @MyQualifier Event<MyObject> event; public void fireEvent(MyObject object, MyTypeValue type) { event.select(new MyTypeAnnotationLiteral(type)).fire(object); } {code} Currently no observer can receive the value of MyTypeValue. I suggest to introduce an interface AnnotatedEvent that extends Annotated and contains this information. It then could be injected via the InjectionPoint like this: {code} public void observeEvent(@Observes @MyType MyObject object, InjectionPoint ip) { MyType annotation = ip.getAnnotated().getAnnotation(MyType.class); MyTypeValue value = annotation.value(); ... } {code}
