AsyncCallback.VoidCallback (Apache ZooKeeper - Server 3.9.1 API)

All Superinterfaces:

AsyncCallback

Enclosing interface:

AsyncCallback
```
@Public
public static interface AsyncCallback.VoidCallback
extends 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).

Modifier and Type	Method	Description
`void`	`processResult(int rc, String path, Object ctx)`	Process the result of the asynchronous call.

- Method Detail
  - processResult
```
void processResult(int rc,
                   String path,
                   Object ctx)
```
    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.
