Using static .values() method of Enum in Generic Class

Question

Hi *,
I tried to do the following:
public class AClass<E extends Enum<E> >  {
     public AClass() {
          E[] values = E.values(); // this DOESN'T work
          for (E e : values) { /* do something */ }
}This is not possible. But how can I access all Enum constants if I use
an Enum type parameter in a Generic class?
Thanks for your help ;-) Stephan

Here's a possible workaround. The generic class isn't adding much in this case; I originally wrote it as a static method that you simply passed the class to:
public class Test21
  public static enum TestEnum { A, B, C };
  public static class AClass<E extends Enum<E>>
    private Class<E> clazz;
    public AClass(Class<E> _clazz)
    {  clazz = _clazz;  }
    public Class<E> getClazz()
    {  return clazz;  }
    public void printConstants()
      for (E e : clazz.getEnumConstants())
        System.out.println(e.toString());
  public static void main(String[] argv)
    AClass<TestEnum> a = new AClass<TestEnum>(TestEnum.class);
    a.printConstants();
}
