- Method Detail
  - done
```
void done()
```
    Method for sync notifications. When this callback method is called, there is a guarantee the data is written on the disk.
    Note:Leave this method as soon as possible, or you would be blocking the whole notification thread
  - onError
```
void onError(int errorCode,
             String errorMessage)
```
    Method for error notifications. Observation: The whole file will be probably failing if this happens. Like, if you delete the file, you will start to get errors for these operations
  - done
```
static void done(Collection<? extends IOCallback> delegates)
```
  - onError
```
static void onError(Collection<? extends IOCallback> delegates,
                    int errorCode,
                    String errorMessage)
