    • getValue

      public final <G extends GtuDataInterface> T getValue​(Query<G> query, Time endTime, java.util.List<TrajectoryGroup<G>> trajectoryGroups)
      Get value for given query over time interval, returning earlier calculated value if possible. This method uses Time.ZERO as start time.
      Type Parameters:
      G - gtu data type
      Parameters:
      query - Query<G>; query
      endTime - Time; start time of interval to calculate indicator over
      trajectoryGroups - List<TrajectoryGroup<G>>; group of trajectories to calculate the indicator for
      Returns:
      value for given query

    • getValue

      public final <G extends GtuDataInterface> T getValue​(Query<G> query, Time startTime, Time endTime, java.util.List<TrajectoryGroup<G>> trajectoryGroups)
      Get value for given query over time interval, returning earlier calculated value if possible.
      Type Parameters:
      G - gtu data type
      Parameters:
      query - Query<G>; query
      startTime - Time; start time of interval to calculate indicator over
      endTime - Time; start time of interval to calculate indicator over
      trajectoryGroups - List<TrajectoryGroup<G>>; group of trajectories to calculate the indicator for
      Returns:
      value for given query
