Method Detail

getValue

public final <G extends GtuDataInterface> T getValue(Query<G> query,
                                                     Time endTime,
                                                     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,
                                                     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

calculate

protected abstract <G extends GtuDataInterface> T calculate(Query<G> query,
                                                            Time startTime,
                                                            Time endTime,
                                                            List<TrajectoryGroup<G>> trajectoryGroups)

Calculate value for given trajectory group.

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 trajectory group
