    37  * A Holder class for a <code>byte</code>

    39  * If an IDL method signature has an IDL <code>octet</code> as an "out"

    41  * <code>ByteHolder</code> as the corresponding
    42  * parameter in the method invocation; for "inout" parameters, the programmer
    43  * must also fill the "in" value to be sent to the server.
    44  * Before the method invocation returns, the ORB will fill in the
    45  * value corresponding to the "out" value returned from the server.
    46  * <P>
    47  * If <code>myByteHolder</code> is an instance of <code>ByteHolder</code>,
    48  * the value stored in its <code>value</code> field can be accessed with
