Class LaneDirectionRecord

java.lang.Object

org.opentrafficsim.road.gtu.lane.perception.LaneDirectionRecord

All Implemented Interfaces:

LaneRecord<LaneDirectionRecord>

public class LaneDirectionRecord
extends Object
implements LaneRecord<LaneDirectionRecord>

A light-weight wrapper for LaneRecord search tools (PerceptionIterator). This is suitable for situations where parts of the network not in the LaneStructure need to be perceived, such as conflicting lanes at intersection conflicts. Searches can only be simple upstream or downstream searches, without lateral movement and without regard of a route. This class should not be used whenever the LaneStructure can be used, as this class builds up a new tree each time step.

Method Detail

getNext

public List<LaneDirectionRecord> getNext()

Returns a list of next lanes. Callers of this method do not have to mind GTUDirectionality, this is taken care of.

Specified by:

getNext in interface LaneRecord<LaneDirectionRecord>

Returns:

List; list of next lanes

getPrev

public List<LaneDirectionRecord> getPrev()

Returns a list of previous lanes. Callers of this method do not have to mind GTUDirectionality, this is taken care of.

Specified by:

getPrev in interface LaneRecord<LaneDirectionRecord>

Returns:

List; list of previous lanes

getStartDistance

public Length getStartDistance()

Returns the distance from a reference to the start of this lane, negative for upstream distance.

Specified by:

getStartDistance in interface LaneRecord<LaneDirectionRecord>

Returns:

Length; the distance from a reference to the start of this lane, negative for upstream distance

getLength

public Length getLength()

Returns the length of the lane.

Specified by:

getLength in interface LaneRecord<LaneDirectionRecord>

Returns:

Length; length of the lane.

getDirection

public GtuDirectionality getDirection()

Returns the direction of travel.

Specified by:

getDirection in interface LaneRecord<LaneDirectionRecord>

Returns:

GTUDirectionality; direction of travel

getLane

public Lane getLane()

Returns the lane.

Specified by:

getLane in interface LaneRecord<LaneDirectionRecord>

Returns:

Lane lane;
