| * A Holder class for a {@code byte} |
| * that is used to store "out" and "inout" parameters in IDL methods. |
| * If an IDL method signature has an IDL {@code octet} as an "out" |
| * or "inout" parameter, the programmer must pass an instance of |
| * {@code ByteHolder} as 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. |
| * <P> |
| * If {@code myByteHolder} is an instance of {@code ByteHolder}, |
| * the value stored in its {@code value} field can be accessed with |
| * {@code myByteHolder.value}. |
