/**
* For the given znode path return the stat and children list.
* <p>
* If the watch is non-null and the call is successful (no exception is thrown),
* a watch will be left on the node with the given path. The watch willbe
* triggered by a successful operation that deletes the node of the given
* path or creates/delete a child under the node.
* <p>
* The list of children returned is not sorted and no guarantee is provided
* as to its natural or lexical order.
* <p>
* A KeeperException with error code KeeperException.NoNode will be thrown
* if no node with the given path exists.

* @since 3.3.0

* @param path
* @param watcher explicit watcher
* @param stat stat of the znode designated by path
* @return an unordered array of children of the node with the given path
* @throws InterruptedException If the server transaction is interrupted.
* @throws KeeperException If the server signals an error with a non-zero error code.
* @throws IllegalArgumentException if an invalid path is specified
