* If an IDL operation signature has an IDL TypeCode
as an "out"
* or "inout" parameter, the programmer must pass an instance of

as the corresponding
* 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.

is an instance of TypeCodeHolder
,

field can be accessed with
