- Method Detail
  - toCells
```
public void toCells(CellSink sink)
```
    Transforms this range in a list of cells that are added to the given sink. IMPORTANT: the order in which the cells are added follows the natural Z-order curve order!
    
    Parameters:
    
    sink - object receiving each cell
  - toCellsWithKnowledge
```
public void toCellsWithKnowledge(CellSink sink,
                                 int depthMax,
                                 int twiceDD,
                                 long rangeLenMin,
                                 long mask)
```
    Same as toCells but with additional informations which are (see parameter list). This version may have better performances since a large part of the cells in a MOC are at the deepest MOC order.
    
    Parameters:
    
    sink - object receiving each cell
    
    depthMax - the depth of the lower possible cell order in the Range (i.e. the MOC order)
    
    twiceDD - (29 - depthMax) << 1, provided not ot have to recompute it
    
    rangeLenMin - 1L << twiceDD, provided not to have to recompute it
    
    mask - 3L << twiceDD, provided not to have to recompute it
