The Holder for Double. For more information on Holder files, see "Generated Files: Holder Files".A Holder class for a
doublethat is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDLdoubleas an "out" or "inout" parameter, the programmer must pass an instance ofDoubleHolderas 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
myDoubleHolderis an instance ofDoubleHolder, the value stored in itsvaluefield can be accessed withmyDoubleHolder.value.- Since:
- JDK1.2
