Constructor Detail

InfrastructureLaneChangeInfo

protected InfrastructureLaneChangeInfo(int requiredNumberOfLaneChanges,
                                       boolean deadEnd)

Constructor for subclasses.

Parameters:

requiredNumberOfLaneChanges - required number of lane changes

deadEnd - whether the need to change lane comes from a dead-end

InfrastructureLaneChangeInfo

public InfrastructureLaneChangeInfo(int requiredNumberOfLaneChanges,
                                    LaneStructureRecord record,
                                    RelativePosition relativePosition,
                                    boolean deadEnd,
                                    LateralDirectionality lat)

Constructor.

Parameters:

requiredNumberOfLaneChanges - required number of lane changes

record - record who's end defines the remaining distance

relativePosition - critical relative position (i.e. nose when driving forward)

deadEnd - whether the need to change lane comes from a dead-end

lat - LateralDirectionality; lateral directionality of required lane changes

Throws:

IllegalArgumentException - if required number of lane changes or remaining distance is negative

NullPointerException - if remaining distance is null

Method Detail

Returns:

whether this reason to change lane is due to a dead-end.

setDeadEnd

public final void setDeadEnd(boolean deadEnd)

Sets whether this reason to change lane is due to a dead-end.

Parameters:

deadEnd - whether the need to change lane comes from a dead-end
