One of our existing apps uses a deprecated form of `vtkUnstructuredGrid::SetCells`. Here it is in [an older Doxygen](https://vtk.org/doc/release/7.1/html/classvtkUnstructuredGrid.html#a02eb2ba6eee9751e8f6f53cd4da0685d):
```auto
void vtkUnstructuredGrid::SetCells (
vtkUnsignedCharArray *cellTypes,
vtkIdTypeArray *cellLocations,
vtkCellArray *cells
)
```
How do I replace it using the latest version of VTK? Can I use this form and omit `cellLocations`?
```auto
void vtkUnstructuredGrid::SetCells (
vtkUnsignedCharArray *cellTypes,
vtkCellArray *cells
)
```

Yes. The information that was in `cellLocations` is now directly embedded in the `vtkCellArray`, so it no longer needs to be specified here.

Great, thank you!
