What is returned by narrow method?

Question

Hi,
Following java code is part of the idlj-generated HelloHelper class. What is returned, When we called narrow() method in the client application code? It is stub or HelloApp.Hello object?
************** HelloHelper class *************************
public static HelloApp.Hello narrow (org.omg.CORBA.Object obj){
if (obj == null)
return null;
else if (obj instanceof HelloApp.Hello)
return (HelloApp.Hello)obj;
else if (!obj._is_a (id ()))
throw new org.omg.CORBA.BAD_PARAM ();
else{
org.omg.CORBA.portable.Delegate delegate = ((org.omg.CORBA.portable.ObjectImpl)obj)._get_delegate ();
HelloApp._HelloStub stub = new HelloApp._HelloStub ();
stub._set_delegate(delegate);
return stub;
*********in the server application code****************
HelloImpl helloImpl = new HelloImpl();
org.omg.CORBA.Object ref = rootpoa.servant_to_reference(helloImpl);Hello href = HelloHelper.narrow(ref);
String name = "Hello";NameComponent[] path = ncRef.to_name(name);ncRef.rebind(path, href);
*********in the client application code****************
static Hello hello;
hello = HelloHelper.narrow(ncRef.resolve_str(name));
Sincerely...

Both. If the object is already a stub it returns it, otherwise it forms a stub from the object (presumably an IOR or the remote object itself) and returns it. In either case the stub is an instance of HelloApp.Hello which I would guess is a remote interface.
