ViewportData (JOSM)

java.lang.Object
- org.openstreetmap.josm.data.ViewportData

```
public class ViewportData
extends java.lang.Object
```
Data class to keep viewport information. This can be either a combination of map center and map scale or a rectangle in east-north coordinate space. Either of those will be null, so the consumer of the ViewportData object has to check, which one is set.
