<DD>Returns the backing delegate instance that methods are forwarded to.
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.
