Method Detail

getValue

public final T getValue(Query query,
                        Time endTime,
                        List<TrajectoryGroup> trajectoryGroups)

Get value for given query over time interval, returning earlier calculated value if possible. This method uses Time.ZERO as start time.

Parameters:

query - query

endTime - start time of interval to calculate indicator over

trajectoryGroups - group of trajectories to calculate the indicator for

Returns:

value for given query

getValue

public final T getValue(Query query,
                        Time startTime,
                        Time endTime,
                        List<TrajectoryGroup> trajectoryGroups)

Get value for given query over time interval, returning earlier calculated value if possible.

Parameters:

query - query

startTime - start time of interval to calculate indicator over

endTime - start time of interval to calculate indicator over

trajectoryGroups - group of trajectories to calculate the indicator for

Returns:

value for given query

calculate

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

Calculate value for given trajectory group.

Parameters:

query - query

startTime - start time of interval to calculate indicator over

endTime - start time of interval to calculate indicator over

trajectoryGroups - group of trajectories to calculate the indicator for

Returns:

value for given trajectory group
