public final class TypeCodeHolder extends Object implements Streamable
The Holder for TypeCode. For more information on Holder files, see "Generated Files: Holder Files".A Holder class for a
TypeCodeobject that is used to store "out" and "inout" parameters in IDL operations. If an IDL operation signature has an IDLTypeCodeas an "out" or "inout" parameter, the programmer must pass an instance ofTypeCodeHolderas 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
myTypeCodeHolderis an instance ofTypeCodeHolder, the value stored in itsvaluefield can be accessed withmyTypeCodeHolder.value.- Since:
- JDK1.2
