Member Enumeration Documentation

Definition of a vehicle state.

Enumerator
NOTIFICATION_DEPARTED 

The vehicle has departed (was inserted into the network)

NOTIFICATION_JUNCTION 

The vehicle arrived at a junction.

NOTIFICATION_SEGMENT 

The vehicle changes the segment (meso only)

NOTIFICATION_LANE_CHANGE 

The vehicle changes lanes (micro only) XXX: What if a vehicle changes lanes and passes a junction simultaneously?

NOTIFICATION_TELEPORT 

The vehicle is being teleported.

NOTIFICATION_PARKING 

The vehicle starts or ends parking.

NOTIFICATION_ARRIVED 

The vehicle arrived at its destination (is deleted)

NOTIFICATION_VAPORIZED 

The vehicle got vaporized.

NOTIFICATION_TELEPORT_ARRIVED 

The vehicle was teleported out of the net.

Definition at line 95 of file MSMoveReminder.h.

bool MSMeanData::MeanDataValueTracker::notifyEnter ( SUMOVehicle veh,
MSMoveReminder::Notification  reason 
)
virtual

Computes current values and adds them to their sums.

The fraction of time the vehicle is on the lane is computed and used as a weight for the vehicle's current values. The "emitted" field is incremented, additionally.

Parameters
[in]vehThe entering vehicle.
[in]reasonhow the vehicle enters the lane

Returns
Always true

bool MSMeanData::MeanDataValueTracker::notifyLeave ( SUMOVehicle veh,

virtual

Called if the vehicle leaves the reminder's lane.

Parameters
vehThe leaving vehicle.
[in]lastPosPosition on the lane when leaving.
[in]isArrivalwhether the vehicle arrived at its destination
[in]isLaneChangewhether the vehicle changed from the lane

bool MSMeanData::MeanDataValues::notifyMove ( SUMOVehicle veh,
SUMOReal  oldPos,
SUMOReal  newPos,
SUMOReal  newSpeed 
)
virtualinherited

Checks whether the reminder still has to be notified about the vehicle moves.

Indicator if the reminders is still active for the passed vehicle/parameters. If false, the vehicle will erase this reminder from it's reminder-container.

Parameters
[in]vehVehicle that asks this reminder.
[in]oldPosPosition before move.
[in]newPosPosition after move with newSpeed.
[in]newSpeedMoving speed.
Returns
True if vehicle hasn't passed the reminder completely.
