Constructor Detail

VariableSampleRateTrajectory

public VariableSampleRateTrajectory(String id)

Construct a new VariableSamplerateTrajectory.

Parameters:

id - String; id of the new Trajectory (id of the GTU)

Method Detail

getCurrentEndTime

public org.djunits.value.vdouble.scalar.Time getCurrentEndTime()

Retrieve the time of the last stored event.

Specified by:

getCurrentEndTime in interface TrajectoryPlot.Trajectory

Returns:

Time; the time of the last stored event

getLastPosition

public Double getLastPosition()

Retrieve the last recorded non-null position, or null if no non-null positions have been recorded yet.

Specified by:

getLastPosition in interface TrajectoryPlot.Trajectory

Returns:

Double; the last recorded position of this Trajectory in meters

getId

public String getId()

Retrieve the id of this Trajectory.

Specified by:

getId in interface TrajectoryPlot.Trajectory

Returns:

Object; the id of this Trajectory

addSample

public void addSample(LaneBasedGTU gtu,
                      Lane lane,
                      double position)
               throws org.opentrafficsim.core.network.NetworkException,
                      org.opentrafficsim.core.gtu.GTUException

Add a trajectory segment sample and update the currentEndTime and currentEndPosition.

Specified by:

addSample in interface TrajectoryPlot.Trajectory

Parameters:

gtu - AbstractLaneBasedGTU; the GTU whose currently committed trajectory segment must be added

lane - Lane; the Lane that the positionOffset is valid for

position - Double; distance in meters from the start of the trajectory

Throws:

org.opentrafficsim.core.network.NetworkException - when car is not on lane anymore

org.opentrafficsim.core.gtu.GTUException - on problems obtaining data from the GTU

recordGTULeftTrajectoryEvent

public void recordGTULeftTrajectoryEvent()

Store that the GTU went off of the trajectory.

size

public int size()

Retrieve the number of stored samples in this Trajectory.

Specified by:

size in interface TrajectoryPlot.Trajectory

Returns:

int; number of stored samples

getTime

public double getTime(int item)

Return the time of the Nth stored sample.

Specified by:

getTime in interface TrajectoryPlot.Trajectory

Parameters:

item - int; the index of the sample

Returns:

double; the time of the sample

getDistance

public double getDistance(int item)

Return the distance of the Nth stored sample.

Specified by:

getDistance in interface TrajectoryPlot.Trajectory

Parameters:

item - int; the index of the sample

Returns:

double; the distance of the sample

toString

public String toString()

Overrides:

toString in class Object
