bool IsDoneWithTraversal() override
Returns false while the iterator is valid.
Default cell iterator for vtkMappedUnstructuredGrid.
void FetchPoints() override
Lookup the cell points in the data set and store them in this->Points.
void IncrementToNextCell() override
Update internal state to point to the next cell.

vtkTemplateTypeMacro(vtkMappedUnstructuredGridCellIterator< Implementation >, vtkCellIterator)
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void ResetToFirstCell() override
Update internal state to point to the first cell.

void SetMappedUnstructuredGrid(vtkMappedUnstructuredGrid< ImplementationType, ThisType > *grid)
void FetchPointIds() override
Lookup the cell point ids in the data set and store them in this->PointIds.
void FetchCellType() override
Lookup the cell type in the data set and store it in this->CellType.
Efficient cell iterator for vtkDataSet topologies.
vtkIdType GetCellId() override
Get the id of the current cell.
