 * @class   vtkExtractSelectedIds
 * @brief   extract a list of cells from a dataset
 *
 * vtkExtractSelectedIds extracts a set of cells and points from within a
 * vtkDataSet. The set of ids to extract are listed within a vtkSelection.
 * This filter adds a scalar array called vtkOriginalCellIds that says what
 * input cell produced each output cell. This is an example of a Pedigree ID
 * which helps to trace back results. Depending on whether the selection has
 * GLOBALIDS, VALUES or INDICES, the selection will use the contents of the
 * array named in the GLOBALIDS DataSetAttribute, and arbitrary array, or the
 * position (tuple id or number) within the cell or point array.
 *
 * @sa
 * vtkSelection vtkExtractSelection
 *
 * @deprecated vtkExtractSelectedIds is deprecated in VTK 9.2 and will be removed.
 * Use `vtkExtractSelection` instead of `vtkExtractSelectedIds`.
 *
 * Example using vtkExtractSelectedIds:
 *
 * vtkNew<vtkExtractSelectedIds> selFilter;
 * selFilter->SetInputConnection(0, sphereSource->GetOutputPort());
 * selFilter->SetInputConnection(1, selectionSource->GetOutputPort());
 *
 * Example using vtkExtractSelection:
 *
 * vtkNew<vtkExtractSelection> selFilter;
 * selFilter->SetInputConnection(0, sphereSource->GetOutputPort());
 * selFilter->SetInputConnection(1, selectionSource->GetOutputPort());
