Dynamically fire CDI event with qualifier with members

Question

I\'m trying to use CDI events in my backend services, on JBoss AS6 - ideally with maximum code reuse.

I can see from the docs I can cut down on the qualifier annotat

Answer 1

There's a slightly cleaner way to do it based on your post:

public class TypeQualifier extends AnnotationLiteral<Type> implements Type{

private TypeEnum type;

public TypeQualifier(TypeEnum t) {
      this.type = t;
}

public TypeEnum value() {
    return type;
}

}

then just fire like this:

dynamicEventFirer.fireEvent(new TypeQualifier(TypeEnum.TYPEA));

Answer 2

You need to declare an abstract TypeQualifier that extends AnnotationLiteral and implements Type

abstract class TypeQualifier extends AnnotationLiteral<Type> implements Type{}

and use it like this

dynamicEventFirer.fireEvent(new TypeQualifier() {
public TypeEnum value() {
    return TypeEnum.TYPEA;
}
});

and later if you want to fire an event with TypeEnum.TYPEB

dynamicEventFirer.fireEvent(new TypeQualifier() {
public TypeEnum value() {
    return TypeEnum.TYPEB;
}
});
