This is done by invoking the non standard - "non_existent" method on it. If it fails an exception will be thrown, - if the exception is not the Forward_Request exception of the POA, - the object is not there. If it is this specific exception, the new - forwarded location can be extracted and returned in the locate reply. - If the call on "non_existent" succeeds, we know the object is there and - return that. - - The client part of the locate request is handled int Locate_Request_Invocation. - The response is checked on the answer. If there, we go on and invoke the - actual method on the distant object. If not there, we fail and throw the proper - exception and if we get forwarded we replace our IIOP profile acordingly. - - <h2>API</h2> - To activate the locate requests, please invoke the non standard method - "_use_locate_requests (CORBA::B_TRUE)" on your CORBA::Object or any - object which inherits form this object. This will activate the locate - request on the first call to the object. The second time and on all - following calls "no" locate request will be used any more. To switch - it on again use "_use_locate_requests (CORBA::B_TRUE)" again. - You can also switch it of by "_use_locate_requests (CORBA::B_FALSE)". - - <HR> - For more details and questions, - <p> - <address><a href="mailto:irfan1@cs.wustl.edu">Irfan Pyarali</a></address> - <p> - <address><a href="mailto:mk1@cs.wustl.edu">Michael Kircher</a></address> - <p> - </body> -</html> - |
