void	processResult(int rc, String path, Object ctx, byte[] data, Stat stat) Process the result of asynchronous calls.

Method Detail

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 - Stat object of the node on given path.
