Let's have a look on the processing in mkgmap:
1. The StyledConverter applies the style to the Way object. This creates a MapRoad object. 2. The MapRoad object is added to the RoadNetwork 3. The MapRoad object is passed through the filters. Some of these filters may not care about routing nodes (CoordNode). But filters usually copy the MapRoad object before modifying it. 4. After all filters have been applied the RoadNetwork is generated.
Do you think my short algo desription is correct? I think it's not bad to try to understand the different processing steps to see the big picture...
I think the problem is that we do some calculations before the filters are applied, for example the StyledConverter calls road.setNumNodes(numNodes); which sets the number of coordNodes in a road. This number is written to the img file, so it causes errors if the number of these nodes doesn't match after the filters were used. I think the same problem may happen with the setStartsWithNode() method. I'd prefer to do these calculations after all the filters were applied, but I don't know yet if it's possible.
