Pure CORBA

oneway Invocations

If you are invoking a oneway operation, you must make the invocation by calling send_oneway() in place of invoke(). It has the following syntax in C++ and Java:

//C++
void CORBA::Request::send_oneway();
//Java
void org.omg.CORBA.Request.send_oneway();

The semantics of send_oneway() depend on the particular version of GIOP used over the connection.

• GIOP 1.0 or 1.1 A call to send_oneway() sends a request message to the server that has the response_expected flag set to false. No reply is sent back from the server, and send_oneway() returns immediately.

• GIOP 1.2 In this case, a call to send_oneway() provides only a hint to the ORB that a reply is not needed. The ORB might ignore this hint and ask for a reply anyway. This would ...
