 * @class   vtkBridgeCellIteratorStrategy
 * @brief   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,
 * @sa
 * vtkGenericCellIterator, vtkBridgeCellIterator, vtkBridgeDataSet, vtkBridgeCellIteratorOnDataSet, vtkBridgeCellIteratorOnDataSetBoundaries, vtkBridgeCellIteratorOnCellBoundaries, vtkBridgeCellIteratorOnCellNeighbors
