Union values can be traversed using the operations defined in <code>DynAny</code>. The first component in the union corresponds to the discriminator; the second corresponds to the actual value of the union. Calling the method <code>next()</code> twice allows you to access both components.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ========
