Review comment:
Do you mean dedup like this?
```scala
@Override
public <T> KVStoreView<T> view(Class<T> type){
return viewWithCondition(type, t -> true);
}
```
It cannot invoke `view` in `viewWithCondition` since `list.view(type)` will
create much more instances than `list.viewWithCondition` indeed.
