iterator used to traverse points
virtual vtkTypeBool IsAtEnd()=0
Is the iterator at the end of traversal?
void PrintSelf(ostream &os, vtkIndent indent) override
Standard VTK construction and type macros.
virtual void Begin()=0
Move iterator to first position if any (loop initialization).
virtual void GetPosition(double x[3])=0
Get the coordinates of the point at the current iterator position.
virtual double * GetPosition()=0
Get the coordinates of the point at the current iterator position.
virtual void Next()=0
Move the iterator to the next position in the list.
vtkGenericPointIterator()
Destructor.
~vtkGenericPointIterator() override
Destructor.
virtual vtkIdType GetId()=0
Return the unique identifier for the point, could be non-contiguous.
