[GraphHopper] Getting lat lon pairs of an edge

[Karim]

Hello,
May be my questions are very basic w.r.t the other questions that are
posted here. Also, that I am new to programming.

I have couple of questions:
1. Given an Edge ID, how to get the (lat,lon) pairs that connect it?
2. Given a single (lat, lon) pair, how to get which edge ID it belongs to?
Because, with Map-matching, I will need atlas 2 points.

Thanks a lot for the help!
