ZooKeeper.removeAllWatches介绍

[英]For the given znode path, removes all the registered watchers of given watcherType.

A successful call guarantees that, the removed watchers won't be triggered.
[中]对于给定的znode路径，删除给定watcherType的所有已注册观察程序。
一个成功的呼叫保证，被移除的监视程序不会被触发。

代码示例

代码示例来源：origin: apache/zookeeper

@Override
  public boolean exec() throws CliWrapperException, MalformedPathException {
    String path = args[1];
    WatcherType wtype = WatcherType.Any;
    // if no matching option -c or -d or -a is specified, we remove
    // the watches of the given node by choosing WatcherType.Any
    if (cl.hasOption("c")) {
      wtype = WatcherType.Children;
    } else if (cl.hasOption("d")) {
      wtype = WatcherType.Data;
    } else if (cl.hasOption("a")) {
      wtype = WatcherType.Any;
    }
    // whether to remove the watches locally
    boolean local = cl.hasOption("l");

    try {
      zk.removeAllWatches(path, wtype, local);
    } catch (IllegalArgumentException ex) {
      throw new MalformedPathException(ex.getMessage());
    } catch (KeeperException|InterruptedException ex) {
      throw new CliWrapperException(ex);
    }
    return true;
  }
}

代码示例来源：origin: apache/zookeeper

private void removeAllWatches(ZooKeeper zk, String path,
    WatcherType watcherType, boolean local, KeeperException.Code rc)
    throws InterruptedException, KeeperException {
  LOG.info("Sending removeWatches req using zk {} path: {} type: {} ",
      new Object[] { zk, path, watcherType });
  if (useAsync) {
    MyCallback c1 = new MyCallback(rc.intValue(), path);
    zk.removeAllWatches(path, watcherType, local, c1, null);
    Assert.assertTrue("Didn't succeeds removeWatch operation",
        c1.matches());
    if (KeeperException.Code.OK.intValue() != c1.rc) {
      KeeperException ke = KeeperException
          .create(KeeperException.Code.get(c1.rc));
      throw ke;
    }
  } else {
    zk.removeAllWatches(path, watcherType, local);
  }
}
