Method Detail

getCurrentEndTime

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

Retrieve the time of the last stored event.

Returns:

Time; the time of the last stored event

getLastPosition

Double getLastPosition()

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

Returns:

Double; the last recorded position of this Trajectory in meters

getId

String getId()

Retrieve the id of this Trajectory.

Returns:

Object; the id of this Trajectory

addSample

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.

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

size

int size()

Retrieve the number of stored samples in this Trajectory.

Returns:

int; number of stored samples

getTime

double getTime(int item)

Return the time of the Nth stored sample.

Parameters:

item - int; the index of the sample

Returns:

double; the time of the sample

getDistance

double getDistance(int item)

Return the distance of the Nth stored sample.

Parameters:

item - int; the index of the sample

Returns:

double; the distance of the sample
