processResult
void processResult(int rc, String path, Object ctx, byte[] data, Stat stat)Process the result of asynchronous calls.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.
- 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.data- The data of the node.stat-Statobject of the node on given path.- See Also:
