Example 1 with FailedDeleteManagerListener

use of org.apache.curator.framework.imps.FailedDeleteManager.FailedDeleteManagerListener in project xian by happyyangyuan.

the class TestFailedDeleteManager method testGuaranteedDeleteOnNonExistentNodeInForeground.

@Test
public void testGuaranteedDeleteOnNonExistentNodeInForeground() throws Exception {
    CuratorFramework client = CuratorFrameworkFactory.newClient(server.getConnectString(), new RetryOneTime(1));
    client.start();
    final AtomicBoolean pathAdded = new AtomicBoolean(false);
    ((CuratorFrameworkImpl) client).getFailedDeleteManager().debugListener = new FailedDeleteManagerListener() {

        @Override
        public void pathAddedForDelete(String path) {
            pathAdded.set(true);
        }
    };
    try {
        client.delete().guaranteed().forPath("/nonexistent");
        Assert.fail();
    } catch (NoNodeException e) {
        // Exception is expected, the delete should not be retried
        Assert.assertFalse(pathAdded.get());
    } finally {
        client.close();
    }
}
