[vtk-developers] Why is GetRange double* even for non double arrays?

[David Doria]

If I have an array like this:

vtkSmartPointer<vtkDoubleArray> distances =
    vtkIntArray::SafeDownCast(polydata->GetPointData()->GetArray("Distances"));

It makes sense to do:

double range[2];
distances->GetRange(range);

But if the array is not a DoubleArray: e.g.

vtkSmartPointer<vtkIntArray> ids =
    vtkIntArray::SafeDownCast(polydata->GetPointData()->GetArray("ids"));

shouldn't one be able to get the range like this:

int range[2];
ids->GetRange(range);

?

Thanks,

David
