Computes the shortest path through a contracted network.
The template parameters are:
E | The edge class to use (MSEdge/ROEdge) |
V | The vehicle class to use (MSVehicle/ROVehicle) |
PF | The prohibition function to use (prohibited_withPermissions/noProhibitions) |
The router is edge-based. It must know the number of edges for internal reasons and whether a missing connection between two given edges (unbuild route) shall be reported as an error or as a warning.
