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

* must also fill the "in" value to be sent to the server.
* Before the method invocation returns, the ORB will fill in the

is an instance of DoubleHolder
,

field can be accessed with
