/**
* The Holder for Double. For more information on
* Holder files, see
* "Generated Files: Holder Files".
* A Holder class for a double
* that is used to store "out" and "inout" parameters in IDL methods.
* If an IDL method signature has an IDL double
as an "out"
* or "inout" parameter, the programmer must pass an instance of
* DoubleHolder
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.
*
* If myDoubleHolder
is an instance of DoubleHolder
,
* the value stored in its value
field can be accessed with
* myDoubleHolder.value
.
