Class AnyOfOperations

java.lang.Object

org.apache.camel.component.zookeeper.operations.ZooKeeperOperation

org.apache.camel.component.zookeeper.operations.AnyOfOperations

All Implemented Interfaces:

WatchedEventProvider

public class AnyOfOperations
extends ZooKeeperOperation
implements WatchedEventProvider

AnyOfOperations is a composite operation of one or more sub operation, executing each in turn until any one succeeds. If any execute successfully, this operation succeeds; if the sub operations are all executed without success it fails.

It is mostly used for test and watch scenarios where a node is tested for existence, data or children, falling back to a corresponding watch operation if the test operation fails.
