```
public static Nc4Chunking factory(Nc4Chunking.Strategy type,
                                  int deflateLevel,
                                  boolean shuffle)
```
    Parameters:
    
    type - Strategy type
    
    deflateLevel - 0 corresponds to no compression and 9 to maximum compression,
    
    shuffle - true to turn shuffling on which may improve compression. This option is ignored unless a non-zero deflation level is specified.
    
    Returns:
