void MSLink::setApproaching	(	SUMOVehicle *	approaching,

Sets the information about an approaching vehicle.

Parameters:

[in] approaching The approaching vehicle

		const std::vector< MSLink * > &	foeLinks,
		const std::vector< MSLane * > &	foeLanes

Sets the request information.

Because traffic lights and junction logics are loaded after links, we have to assign the information about the right-of-way requests and responses after the initialisation.

Parameters:
