### Question:
EPTemplateUtil { public static boolean isPlain(final IpPrefix key) { return key.getIpv4Prefix().getValue().endsWith(FULL_IPV4_MASK_SUFFIX); } private  EPTemplateUtil(); static boolean isPlain(final IpPrefix key); static SubnetInfoKeyDecorator buildSubnetInfoKey(@Nonnull final IpPrefix value); static ListenableFuture<OptionalMutablePair<L, R>> compositeRead(
            final ListenableFuture<Optional<L>> leftRead, final ListenableFuture<Optional<R>> rightRead); static ListenableFuture<Pair<K, V>> wrapToPair(
            final K keyItem,
            final ListenableFuture<Optional<V>> valueFromRead); static ListenableFuture<Optional<V>> wrapToOptional(final ListenableFuture<V> value); static Ordering<EndpointGroupId> createEndpointGroupIdOrdering(); static Ordering<ConditionName> createConditionNameOrdering(); static Ordering<Sgt> createSgtOrdering(); static final String FULL_IPV4_MASK_SUFFIX; }### Answer:
@Test public void testIsPlain() throws Exception { Assert.assertFalse(EPTemplateUtil.isPlain(IP_PREFIX_24)); Assert.assertTrue(EPTemplateUtil.isPlain(IP_PREFIX_32)); }
