Data members in vtkPolyDataConnectivityFilter should be protected, not private
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
A lot of the fields used internally in vtkPolyDataConnectivityFilter are private:
private: // used to support algorithm execution vtkDataArray *CellScalars; vtkIdList *NeighborCellPointIds; vtkIdType *Visited; vtkIdType *PointMap; vtkDataArray *NewScalars; vtkIdType RegionNumber; vtkIdType PointNumber; vtkIdType NumCellsInRegion; vtkDataArray *InScalars; vtkPolyData *Mesh; vtkIdList *Wave; vtkIdList *Wave2; vtkIdList *PointIds; vtkIdList *CellIds;
Unfortunately, this is problematic when trying to extend the class, I have to copy it completely instead of simply deriving from it.
