public final class LongHolder extends Object implements Streamable
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.
