 * A Holder class for a {@code ServiceInformation} object
 * that is used to store "out" and "inout" parameters in IDL methods.
 * If an IDL method signature has an IDL {@code xxx} as an "out"
 * or "inout" parameter, the programmer must pass an instance of
 * {@code ServiceInformationHolder} 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 myServiceInformationHolder} is an instance of {@code ServiceInformationHolder},
 * the value stored in its {@code value} field can be accessed with
 * {@code myServiceInformationHolder.value}.
