所有超级接口:

AutoCloseable

所有已知实现类:

FetchedResult, LazyResult, LocalResult, ResultRemote, ResultWithPaddedStrings, SimpleResult
```
public interface ResultInterface
extends AutoCloseable
```
The result interface is used by the LocalResult and ResultRemote class. A result may contain rows, or just an update count.
