Hi @iamsmkr,
I'm not really sure what you're looking to do. The BigIntVector class
implements a version of get(int) that returns a long rather than int (since
it's a BIG int vector). The only way to map over the three types would be to
use long as the return type.
```
List<Long> rowData = vectors.map(v ->
v.get(row)).boxed().collect(Collectors.toList());
```
I didn't attempt to compile that, as I'm not entirely sure I'm answering the
right question. It might need some tweaking.
