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>myFloatHolder</code> is an instance of <code>FloatHolder</code>,
48 * the value stored in its <code>value</code> field can be accessed with
