    Parameters:
    
    pos - position where a zero word was added
  - setOne
```
public final void setOne(int pos)
```
    Parameters:
    
    pos - position were a 11...1 word was added
  - dispatch
```
public abstract void dispatch(BitmapStorage32 out,
                              int runBegin,
