OffsetIterator (JOSM)

java.lang.Object
- org.openstreetmap.josm.data.osm.visitor.paint.OffsetIterator

All Implemented Interfaces:

java.util.Iterator<MapViewState.MapViewPoint>
```
public class OffsetIterator
extends java.lang.Object
implements java.util.Iterator<MapViewState.MapViewPoint>
```
Iterates over a list of Way Nodes and returns screen coordinates that represent a line that is shifted by a certain offset perpendicular to the way direction. There is no intention, to handle consecutive duplicate Nodes in a perfect way, but it should not throw an exception.
