Method Detail

addIterable

public void addIterable(RelativeLane lane,
                        AbstractPerceptionReiterable<H,U> iterable)

primaryIterator in class AbstractPerceptionReiterable<H extends Headway,U>

Returns:

Iterator; primary iterator

perceive

public H perceive(LaneBasedGTU perceivingGtu,
                  U object,
                  Length distance)
           throws GTUException,
                  ParameterException

Returns a perceived version of the underlying object.

Specified by:

perceive in class AbstractPerceptionReiterable<H extends Headway,U>

Parameters:

perceivingGtu - LaneBasedGTU; perceiving GTU

object - U; underlying object

distance - Length; distance to the object

Returns:

H; perceived version of the underlying object

Throws:

GTUException - on exception

ParameterException - on invalid parameter value or missing parameter
