Implementation of vtkCellIterator specialized for vtkUnstructuredGrid.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void SetUnstructuredGrid(vtkUnstructuredGrid *ug)
void IncrementToNextCell() override
Update internal state to point to the next cell.
void ResetToFirstCell() override
Update internal state to point to the first cell.
vtkSmartPointer< vtkIdTypeArray > FaceLocs
bool IsDoneWithTraversal() override
Returns false while the iterator is valid.
vtkIdType GetCellId() override
Get the id of the current cell.
