process

public void process(WatchedEvent event)

process in interface Watcher

processResult

public void processResult(int rc,
                          java.lang.String path,
                          java.lang.Object ctx,
                          java.util.List<java.lang.String> children)

Description copied from interface: AsyncCallback.ChildrenCallback

Process the result of the asynchronous call.

On success, rc is KeeperException.Code.OK.

On failure, rc is set to the corresponding failure code in KeeperException.

• KeeperException.Code.NONODE - The node on given path doesn't exist for some API calls.

Specified by:

processResult in interface AsyncCallback.ChildrenCallback

Parameters:

rc - The return code or the result of the call.

path - The path that we passed to asynchronous calls.

ctx - Whatever context object that we passed to asynchronous calls.

children - An unordered array of children of the node on given path.
