create - create a znode

create(String path, byte[] data, List acl, CreateMode createMode)

exists - CHECK WHETHER a znode exists and its information

exists(String path, BOOLEAN watcher)

getData - get data from a particular znode

getData(String path, Watcher watcher, Stat stat)

setData - set data in a particular znode

setData(String path, byte[] data, int version)

getChildren - get all sub-nodes available in a particular znode

getChildren(String path, Watcher watcher)

delete - get a particular znode and all its children

delete(String path, int version)

close - close a connection
