Subject getChildren question.
Date Tue, 13 Nov 2012 19:47:52 GMT
Does anybody have any idea about importance of object parameter in this below method? What
exactly it does if we provide some object? Documentation didn't provide any details about
this extra parameter. Appreciate your time.



public void getChildren(String path,

                        Watcher watcher,

                        AsyncCallback.ChildrenCallback<http://zookeeper.apache.org/doc/r3.4.4/api/org/apache/zookeeper/AsyncCallback.ChildrenCallback.html>
cb,

                        Object ctx)

http://zookeeper.apache.org/doc/r3.4.4/api/index.html


for example

zk.getChildren("/node/child1/subchild", watcher, childrencallback, Context.MESSAGE);


where Context is enum

private enum Context {

        MESSAGE,
        LOCK;
    }
