>>You must create a sub class, this then allows Java to resolve the type variables

Hi; In method, public void fireEvent(Object event, Annotation... qualifiers) in BeanManager; spec specifies that runtime event type can not be TypeVariable. But when I look at portable events, all of them contain type variable. For Example; ProcessAnnotatedType<X> When fires this event, event.getClass.getTypeVariables always contain TypeVariable. Is this true? Thanks; --Gurkan _______________________________________________ webbeans-dev mailing list webbeans-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/webbeans-dev

I believe this method all return's type variables.

The type variables of a parameterized type can sometimes be resolved to an actual type, sometimes they can't. This is defined by the Java Language Spec (where it discusses type inference). They can in the case of a subclass of a generic type, they can't for the class itself. > > --Gurkan > > From: Pete Muir <pmuir(a)redhat.com&gt; > To: Gurkan Erdogdu <gurkanerdogdu(a)yahoo.com&gt; > Cc: webbeans-dev(a)lists.jboss.org > Sent: Wednesday, August 26, 2009 10:21:54 PM > Subject: Re: [webbeans-dev] TypeVariabe Event Type > > Yes, you can't fire an event of type Foo<T>.
