CDI: best way to get Class object from subclass

Imagine having the following class in a JEE project using a CDI container:

abstract class C <Implementer extends C> { ... }

What is the best way of getting a Class<Implementer> object to use in C?

I imagine something along the lines of using a producer and injecting it with @Inject Class<Implementer> impl;

Any ideas are appreciated.
