ExistsBuilderImpl

public ExistsBuilderImpl(CuratorFrameworkImpl client,
                         Backgrounding backgrounding,
                         org.apache.zookeeper.Watcher watcher,

Method Detail

creatingParentsIfNeeded

public ACLableExistBuilderMain creatingParentsIfNeeded()

Description copied from interface: ExistsBuilder

Causes any parent nodes to get created if they haven't already been

Specified by:

creatingParentsIfNeeded in interface ExistsBuilder

Returns:

this

creatingParentContainersIfNeeded

public ACLableExistBuilderMain creatingParentContainersIfNeeded()

Description copied from interface: ExistsBuilder

Causes any parent nodes to get created using CreateMode.CONTAINER if they haven't already been. IMPORTANT NOTE: container creation is a new feature in recent versions of ZooKeeper. If the ZooKeeper version you're using does not support containers, the parent nodes are created as ordinary PERSISTENT nodes.

creatingParentContainersIfNeeded in interface ExistsBuilder

Returns:

this

Specified by:

withACL in interface ACLable<ExistsBuilderMain>

Parameters:

aclList - the ACL list to use

Returns:

this
