[GraphHopper] create graph structure from OSM data

[Philipp Kraus]

Hello,

I'm new with graphhopper and I would like to create a full graph of a OSM for a simulation, so each edge must be sampled into cells.
My first question is, how can I create a sampling of the edges?

I know I can convert a OSM with the shell script graphhopper.sh into a directory with edges and vertex data, but I have checked the GraphHopper.java
for creating my own OSM converting structure, because my application should create the GraphHopper data on-fly, but I cannot create
a working source code. Can anybody explain me, in which steps the OSM file must be converted into GraphHopper data directory?

Thanks

Phil
