@Deprecated public class EnsurePath extends Object
Utility to ensure that a particular path is created.
The first time it is used, a synchronized call to ZKPaths.mkdirs(ZooKeeper, String)
is made to
ensure that the entire path has been created (with an empty byte array if needed). Subsequent
calls with the instance are un-synchronized NOPs.
Usage:
EnsurePath ensurePath = new EnsurePath(aFullPathToEnsure); ... String nodePath = aFullPathToEnsure + "/foo"; ensurePath.ensure(zk); // first time syncs and creates if needed zk.create(nodePath, ...); ... ensurePath.ensure(zk); // subsequent times are NOPs zk.create(nodePath, ...);
