Where are the pillar nodes stored?


I have read the documentation over here: https://github.com/graphhopper/graphhopper/blob/master/docs/core/technical.md and as far as I understand only the tower nodes are stored in the nodes & edges lists. I am wondering where and how the pillar nodes are stored? Is there another graph with both pillar and tower nodes which is used to reconstruct the polyline after the routing is done?

This is stored via edge.fetchWayGeometry and linked from the edges storage (“properties”) to the geometries storage.
