### Question:
LayoutVersion { public static boolean supports(final Feature f, final int lv) { final EnumSet<Feature> set = map.get(lv); return set != null && set.contains(f); }  static String getString(); static boolean supports(final Feature f, final int lv); static int getCurrentLayoutVersion();  }### Answer:
@Test public void testRelease203() { assertTrue(LayoutVersion.supports(Feature.DELEGATION_TOKEN, Feature.RESERVED_REL20_203.lv)); }
@Test public void testRelease204() { assertTrue(LayoutVersion.supports(Feature.DELEGATION_TOKEN, Feature.RESERVED_REL20_204.lv)); }
