/**
 * The mapping of a CORBA <code>enum</code> tagging
 * <code>SET_OVERRIDE</code> and <code>ADD_OVERRIDE</code>, which
 * indicate whether policies should replace the
 * existing policies of an <code>Object</code> or be added to them.
 * <P>
 * The method {@link omg.org.CORBA.Object._set_policy_override} takes
 * either <code>SetOverrideType.SET_OVERRIDE</code> or
 * <code>SetOverrideType.ADD_OVERRIDE</code> as its second argument.
 * The method <code>_set_policy_override</code>
 * creates a new <code>Object</code> initialized with the
 * <code>Policy</code> objects supplied as the first argument.  If the
 * second argument is <code>ADD_OVERRIDE</code>, the new policies
 * are added to those of the <code>Object</code> instance that is
 * calling the <code>_set_policy_override</code> method.  If
 * <code>SET_OVERRIDE</code> is given instead, the existing policies
 * are replaced with the given ones.
