Can I put a filter into a lambda?

Show all headers | View raw

I haven't gotten around to mastering the lambda syntax.
I have a JTable with a custom row sorter building an index of all model rows:

rowToModelIndex.clear();
if (modelRowCount > 0) {
     if (getRowFilter() != null) {
          for (int r = 0; r < modelRowCount; r++) {
               if (include(r)) {
                    rowToModelIndex.add(r);
               }
          }
     } else {
          rowToModelIndex.addAll(Stream.iterate(firstRow, n -> n + 1).limit(modelRowCount).collect(Collectors.toList()));
     }
}

If it's a straight up series it's a lambda.  Can the filter loop be also?  I would guess that would be more efficient.
