// .NAME vtkBridgeCellIteratorStrategy - Interface used by vtkBridgeCellIterator
// vtkBridgeCellIterator has different behaviors depending on the way it is
// initialized. vtkBridgeCellIteratorStrategy is the interface for one of those
// behaviors. Concrete classes are vtkBridgeCellIteratorOnDataSet,
// vtkBridgeCellIteratorOnDataSetBoundaries,
// vtkBridgeCellIteratorOnCellBoundaries,
// vtkBridgeCellIteratorOnCellNeighbors,
// .SECTION See Also
