Method Details

getKeeperState

public abstract org.apache.zookeeper.Watcher.Event.KeeperState getKeeperState()

Returns the error condition that temporarily triggered the watcher. NOTE: the watcher will most likely still be set. Use reset() to stage on the successful trigger

Returns:

state

reset

public abstract CompletionStage<org.apache.zookeeper.WatchedEvent> reset()

ZooKeeper temporarily triggers watchers when there is a connection event. However, the watcher stays set for the original operation. Use this method to reset with a new completion stage that will allow waiting for a successful trigger.
