From vtkDataSet.h: (superclass of vtkPolyData and vtkUnstructuredGrid)

/**

  • Get type of cell with cellId such that: 0 <= cellId < NumberOfCells.
  • THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND
  • THE DATASET IS NOT MODIFIED
    */
    virtual int GetCellType(vtkIdType cellId) = 0;
