defines cell interface
iterator used to traverse cells
virtual void Next()=0
Move the iterator to the next position in the list.
virtual vtkTypeBool IsAtEnd()=0
Is the iterator at the end of traversal?
virtual void Begin()=0
Move iterator to first position if any (loop initialization).
virtual vtkGenericAdaptorCell * NewCell()=0
Create an empty cell.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard VTK construction and type macros.
virtual vtkGenericAdaptorCell * GetCell()=0
Get the cell at the current traversal position.
~vtkGenericCellIterator() override
virtual void GetCell(vtkGenericAdaptorCell *c)=0
Get the cell at current position.
