- All Superinterfaces:
AsyncCallback
- Enclosing interface:
AsyncCallback
This callback doesn't retrieve anything from the node. It is useful for some APIs
that doesn't want anything sent back, e.g.
ZooKeeper.sync(String, AsyncCallback.VoidCallback, Object)

Method Details
-
processResult
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.KeeperException.Code.BADVERSION
- The given version doesn't match the node's version for some API calls.KeeperException.Code.NOTEMPTY
- the node has children and some API calls cannot succeed, e.g.ZooKeeper.delete(String, int, AsyncCallback.VoidCallback, Object)
.
- 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.- See Also:
