Re: Generics and reflection

Hi.

I would like to find, at run-time, the actual return type of a generic
method.
For a parameterized return type, that's OK, but what about a
TypeVariable return type ??

Suppose we have the following:

abstract class Generic<T> {
  private T genericInstance;
  public T getGeneric() {
    return genericInstance;
  }
  public void setGeneric(T instance) {
    genericInstance = instance;
  }
}

// Recursive structure
class Concrete extends Generic<Concrete> {
}

The class Concrete actually defines a method which looks like:
public Concrete getGeneric();

But I just can't figure out, and I don't even know if it's possible,
how to find that this method returns an instance of Concrete.

Concrete.class.getMethod("getGeneric", null).getGenericReturnType()
returns a TypeVariable, and I just can't see how to do from it !
 
Thanks !
