Number of selected rows in GridBandedTableView

Number of selected rows in GridBandedTableView was created by Andrey Florinsky
What is the easiest way to get the number of selected rows in a GridBandedTableView?
I am doing as shown below, but it's bad for large data:
GridSelectionIterator* selection = m_view->selectionIterator();
int selectCount = 0;
while (!selection->end())
{
    ++selectCount;
    const int indx = selection->row()->modelRowIndex();
    while (!selection->end() && indx == selection->row()->modelRowIndex())
        selection->next();
}

selectionIterator() is deprecated in latest version of the grid. This week will be released an update. With this version it will be possible to get the selected rows count this way:
    Qtitan::GridTableView* view = m_grid->view<Qtitan::GridTableView>();
    view->selection()->ranges()[0].bottom() - view->selection()->ranges()[0].top();

P.S. Please note, In current version selection()->ranges() function has a private declaration.
