15  * Interface containing methods which are implemented differently in different
16  * versions of the JDK.
17  *
18  * <p>The methods should not be called directly, only via the corresponding
19  * static methods in {@link mondrian.olap.Util}, namely:<ul>
20  * <li>{@link mondrian.olap.Util#enumSetOf(Enum, Enum[])}</li>
21  * <li>{@link mondrian.olap.Util#enumSetNoneOf(Class)}</li>
22  * <li>{@link mondrian.olap.Util#enumSetAllOf(Class)}</li>
23  * </ul></p>
24  *
25  * <p>This interface could in principle be extended to allow native
26  * implementations of methods, or to serve as a factory for entire classes
27  * which have different implementations in different environments.</p>
