   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.
