 Abstract subclasses generally override this method with an abstract method
 that has a more specific return type, such as <A HREF="../../../../../com/google/common/collect/ForwardingSet.html#delegate()"><CODE>ForwardingSet.delegate()</CODE></A>. Concrete subclasses override this method to supply
 the instance being decorated.
