> if you extend TypedWriter you must implement 
> {code}
>   protected abstract void doOpen(C checkpoint);
>   protected abstract C doCheckpointInfo();
>   protected abstract void doWriteItems(List<R> items);
> {code}
> but in many cases you won’t do that.
> BufferedItemReader can extend NoStateItemWriter which provides a default implementation for doOpen() doCheckpointInfo()
