+<div class="block">This is the main class of ZooKeeper client library. To use a ZooKeeper
+ service, an application must first instantiate an object of ZooKeeper class.
+ All the iterations will be done by calling the methods of ZooKeeper class.
+ The methods of this class are thread-safe unless otherwise noted.
+ <p>
+ Once a connection to a server is established, a session ID is assigned to the
+ client. The client will send heart beats to the server periodically to keep
+ the session valid.
+ <p>
+ The application can call ZooKeeper APIs through a client as long as the
+ session ID of the client remains valid.
+ <p>
+ If for some reason, the client fails to send heart beats to the server for a
+ prolonged period of time (exceeding the sessionTimeout value, for instance),
+ the server will expire the session, and the session ID will become invalid.
+ The client object will no longer be usable. To make ZooKeeper API calls, the
+ application must create a new client object.
+ <p>
+ If the ZooKeeper server the client currently connects to fails or otherwise
+ does not respond, the client will automatically try to connect to another
+ server before its session ID expires. If successful, the application can
+ continue to use the client.
+ <p>
+ The ZooKeeper API methods are either synchronous or asynchronous. Synchronous
+ methods blocks until the server has responded. Asynchronous methods just queue
+ the request for sending and return immediately. They take a callback object that
+ will be executed either on successful execution of the request or on error with
+ an appropriate return code (rc) indicating the error.
+ <p>
+ Some successful ZooKeeper API calls can leave watches on the "data nodes" in
+ the ZooKeeper server. Other successful ZooKeeper API calls can trigger those
+ watches. Once a watch is triggered, an event will be delivered to the client
+ which left the watch at the first place. Each watch can be triggered only
+ once. Thus, up to one event will be delivered to a client for every watch it
+ leaves.
+ <p>
+ A client needs an object of a class implementing Watcher interface for
+ processing the events delivered to the client.
+
+ When a client drops current connection and re-connects to a server, all the
+ existing watches are considered as being triggered but the undelivered events
+ are lost. To emulate this, the client will generate a special event to tell
+ the event handler a connection has been dropped. This special event has type
+ EventNone and state sKeeperStateDisconnected.</div>
