public final class LongHolder extends Object implements Streamable
The Holder for Long. For more information on Holder files, see "Generated Files: Holder Files".A Holder class for a
longthat is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDLlong longas an "out" or "inout" parameter, the programmer must pass an instance ofLongHolderas 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
myLongHolderis an instance ofLongHolder, the value stored in itsvaluefield can be accessed withmyLongHolder.value.- Since:
- JDK1.2
