[omniORB] Re: distinguishing remote and local objects

[Sai-Lai Lo]

I don't like to suggest you a hack that is neither portable nor will be
compatible with omniORB 3. But if you really need it now and you don't mind
changing your code later. You can use this internal function.

CORBA::Object_ptr obj;

if (!CORBA::is_nil(obj)) {
   if (obj->PR_getobj()->is_proxy()) {
      // This object reference points to a non-local object
   }
   else {
      // This object is a local object.
   }
}

With the POA (omniORB 3), you can ask if an object reference points to an
object in a particular POA. I think this in effect gives you the
information you want. Look up a CORBA text book for details.
