* A Holder class for a long
* that is used to store "out" and "inout" parameters in IDL methods.
* If an IDL method signature has an IDL long long as an "out"
* or "inout" parameter, the programmer must pass an instance of
* LongHolder 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 myLongHolder is an instance of LongHolder,
* the value stored in its value field can be accessed with
* myLongHolder.value.
