`details=road_class_link` lacking documentation

I don’t believe there is any documentation available for what exactly this property means.

Does anybody know?

OSM has extra highway types for links: https://wiki.openstreetmap.org/wiki/Key:highway#Link_roads

GraphHopper only uses the base types and carries the link information as an extra field.

Oh, I see. So the road_class_link is just indicating whether it is a “link” of the corresponding road_class.

Good to know, I wasn’t able to find that info documented anywhere. Hopefully this will be useful for others in the future.
