public final class StringHolder extends Object implements Streamable
The Holder for String. For more information on Holder files, see "Generated Files: Holder Files".A Holder class for a
Stringthat is used to store "out" and "inout" parameters in IDL operations. If an IDL operation signature has an IDLstringas an "out" or "inout" parameter, the programmer must pass an instance ofStringHolderas 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
myStringHolderis an instance ofStringHolder, the value stored in itsvaluefield can be accessed withmyStringHolder.value.- Since:
- JDK1.2
