 * used to store "out" and "inout" parameters in IDL methods.

 * If an IDL method signature has a CORBA Object reference as an "out"

 * or "inout" parameter, the programmer must pass an instance of

 * parameter in the method invocation; for "inout" parameters, the programmer

 * must also fill the "in" value to be sent to the server.

 * Before the method invocation returns, the ORB will fill in the

 * value corresponding to the "out" value returned from the server.
