Uses of Watcher in org.apache.zookeeper
 

Methods in org.apache.zookeeper that return types with arguments of type Watcher
 Set<Watcher> ClientWatchManager.materialize(Watcher.Event.KeeperState state, Watcher.Event.EventType type, String path)
          Return a set of watchers that should be notified of the event.
 

Methods in org.apache.zookeeper with parameters of type Watcher
 Stat ZooKeeper.exists(String path, Watcher watcher)
          Return the stat of the node of the given path.
 void ZooKeeper.exists(String path, Watcher watcher, AsyncCallback.StatCallback cb, Object ctx)
          The asynchronous version of exists.
 List<String> ZooKeeper.getChildren(String path, Watcher watcher)
          Return the list of the children of the node of the given path.
 void ZooKeeper.getChildren(String path, Watcher watcher, AsyncCallback.Children2Callback cb, Object ctx)
          The asynchronous version of getChildren.
 void ZooKeeper.getChildren(String path, Watcher watcher, AsyncCallback.ChildrenCallback cb, Object ctx)
          The asynchronous version of getChildren.
 List<String> ZooKeeper.getChildren(String path, Watcher watcher, Stat stat)
          For the given znode path return the stat and children list.
 void ZooKeeper.getData(String path, Watcher watcher, AsyncCallback.DataCallback cb, Object ctx)
          The asynchronous version of getData.
 byte[] ZooKeeper.getData(String path, Watcher watcher, Stat stat)
          Return the data and the stat of the node of the given path.
 void ZooKeeper.register(Watcher watcher)
          Specify the default watcher for the connection (overrides the one specified during construction).
 

Constructors in org.apache.zookeeper with parameters of type Watcher
ZooKeeper(String connectString, int sessionTimeout, Watcher watcher)
          To create a ZooKeeper client object, the application needs to pass a connection string containing a comma separated list of host:port pairs, each corresponding to a ZooKeeper server.
ZooKeeper(String connectString, int sessionTimeout, Watcher watcher, boolean canBeReadOnly)
          To create a ZooKeeper client object, the application needs to pass a connection string containing a comma separated list of host:port pairs, each corresponding to a ZooKeeper server.
ZooKeeper(String connectString, int sessionTimeout, Watcher watcher, long sessionId, byte[] sessionPasswd)
          To create a ZooKeeper client object, the application needs to pass a connection string containing a comma separated list of host:port pairs, each corresponding to a ZooKeeper server.
ZooKeeper(String connectString, int sessionTimeout, Watcher watcher, long sessionId, byte[] sessionPasswd, boolean canBeReadOnly)
          To create a ZooKeeper client object, the application needs to pass a connection string containing a comma separated list of host:port pairs, each corresponding to a ZooKeeper server.
