  - tileComputed
```
public void tileComputed(TileComputationEvent event)
```
    Description copied from class: TileComputationObserver
    
    Called each time a tile has been computed. This method is usually called asynchronously by multiple threads. It should perform very fast.
    
    Specified by:
    
    tileComputed in class TileComputationObserver
    
    Parameters:
    
    event - The tile computation event.
  - stop
```
public void stop()
```
    Description copied from class: TileComputationObserver
    
    Stops observation of tile computation events.
    
    Specified by:
    
    stop in class TileComputationObserver
