Using generic event with Otto event bus

Question

I use Otto event bus to subscribe for Volley Requests. I want to use this generic class but the wrong fragment (subscriber) tries to handle the event. Is it possible to use a generic class or is randomly every subscriber of the VolleyResultEvent, independent of the generic type, called?

public class VolleyResultEvent<T> {

    public final VolleyResult result;
    public final T content;

    public VolleyResultEvent(VolleyResult result, T content) {
        this.result = result;
        this.content = content;
    }

    public enum VolleyResult {
        SUCCESS, ERROR
    }

}

Every subscriber of VolleyResultEvent will be called regardless of type generics. Either would you want to make several subclasses of VolleyResultEvent according to the number of types you're having; or implement a matching function which, for example, would compare event id (or type) with subscriber's id (or type) and allow further processing if those are equal.

way is it like this? different generics should actually be different type, aren't they? – benchuk Sep 17 '14 at 17:16

This is a result of type erasure in Java :/ See: http://docs.oracle.com/javase/tutorial/java/generics/erasure.html – Christian Brüggemann Mar 02 '15 at 12:17
