public final class ByteHolder extends Object implements Streamable
The Holder for Byte. For more information on Holder files, see "Generated Files: Holder Files".A Holder class for a
bytethat is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDLoctetas an "out" or "inout" parameter, the programmer must pass an instance ofByteHolderas 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
myByteHolderis an instance ofByteHolder, the value stored in itsvaluefield can be accessed withmyByteHolder.value.- Since:
- JDK1.2
