Example 11 with Watcher

use of io.etcd.jetcd.Watch.Watcher in project jetcd by coreos.

the class WatchTest method testWatchOnPut.

@ParameterizedTest
@MethodSource("parameters")
public void testWatchOnPut(final Client client) throws Exception {
    final ByteSequence key = randomByteSequence();
    final ByteSequence value = randomByteSequence();
    final AtomicReference<WatchResponse> ref = new AtomicReference<>();
    try (Watcher watcher = client.getWatchClient().watch(key, ref::set)) {
        client.getKVClient().put(key, value).get();
        await().atMost(TIME_OUT_SECONDS, TimeUnit.SECONDS).untilAsserted(() -> assertThat(ref.get()).isNotNull());
        assertThat(ref.get()).isNotNull();
        assertThat(ref.get().getEvents().size()).isEqualTo(1);
        assertThat(ref.get().getEvents().get(0).getEventType()).isEqualTo(EventType.PUT);
        assertThat(ref.get().getEvents().get(0).getKeyValue().getKey()).isEqualTo(key);
    }
}

Example 12 with Watcher

use of io.etcd.jetcd.Watch.Watcher in project jetcd by coreos.

    final ByteSequence key = randomByteSequence();
    final AtomicReference<Throwable> ref = new AtomicReference<>();
    // Try to listen from previous revision on
    final WatchOption options = WatchOption.newBuilder().withRevision(getCompactedRevision(client, key)).build();
    final Watch wc = client.getWatchClient();
    try (Watcher watcher = wc.watch(key, options, Watch.listener(TestUtil::noOpWatchResponseConsumer, ref::set))) {
        await().atMost(TIME_OUT_SECONDS, TimeUnit.SECONDS).untilAsserted(() -> assertThat(ref.get()).isNotNull());
        assertThat(ref.get().getClass()).isEqualTo(CompactedException.class);
