void MSLink::setApproaching ( SUMOVehicle approaching,
SUMOTime  arrivalTime,
SUMOReal  speed,
bool  setRequest 
)

Sets the information about an approaching vehicle.

The information is stored in myApproachingVehicles.

Parameters:
[in]approachingThe approaching vehicle

unsigned int  respondIdx,
bool  isCrossing,
bool  isCont,
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:
[in]requestIdxThis link's index within this request
[in]respondIdxThis link's index within this respond
[in]foesThis link's foes
Todo:
Unsecure!

Parameters:
[in]stateThe current state of the link
