Re: [seam-dev] CDI with generic class and the hell of type erasure.

Hey guys, how you doing? I'm trying to achieve something that might be impossible, but before concluding that, I'd like to ask you, CDI gurus! I have the following class: public class Foo<T> { public TypedQuery<T> getQuery(){ } } As you can Imagine, inside my getQuery method, I'd have to use "T.class" to make it TypedQuery. which is impossible due java generics type erasure. so I'd have to build a private field to hold the t.class for me. public class Foo<T> { private Class<T> klass; public TypedQuery<T> getQuery(){ } public void setKlass(Class<T> klass){ this.klass = klass; } } The problem is that forcing this 'setKlass' feels very ugly to the api, and it's not very error prone, since one could easily forget to set this configuration. So I had an Idea: force the setKlass inside the constructor: public class Foo<T> { private Class<T> klass; public Foo(Class<T> klass){ this.klass = klass; } public TypedQuery<T> getQuery(){ } } Unfortunatelly, this breaks cdi, since it cannot inject it anymore. At least AFAIK. So, is there a way out of this? maybe using a secret solder feature? _______________________________________________ seam-dev mailing list seam-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/seam-dev
