int vtkIdType
Definition: vtkType.h:345
virtual void FetchCellType()=0
Lookup the cell type in the data set and store it in this->CellType.
Implementation of vtkCellIterator using vtkPointSet API.
virtual void ResetToFirstCell()=0
Update internal state to point to the first cell.
virtual void IncrementToNextCell()=0
Update internal state to point to the next cell.
virtual vtkIdType GetCellId()=0
Get the id of the current cell.
virtual void FetchPointIds()=0
Lookup the cell point ids in the data set and store them in this->PointIds.
a simple class to control print indentation
Definition: vtkIndent.h:33
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkSmartPointer< vtkPointSet > PointSet
virtual void FetchPoints()=0
Lookup the cell points in the data set and store them in this->Points.
Efficient cell iterator for vtkDataSet topologies.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
virtual bool IsDoneWithTraversal()=0
Returns false while the iterator is valid.
vtkSmartPointer< vtkPoints > PointSetPoints
represent and manipulate 3D points
