Method Summary

Modifier and Type	Method and Description
C	accumulateEntry(C cumulative, LaneBasedGTU gtu, Detector loopDetector) Returns an accumulated value for when the front reaches the detector.
C	accumulateExit(C cumulative, LaneBasedGTU gtu, Detector loopDetector) Returns an accumulated value for when the rear leaves the detector.
A	aggregate(C cumulative, int count, org.djunits.value.vdouble.scalar.Duration aggregation) Returns an aggregated value.
String	getName() Returns the value name.
C	identity() Returns the initial value before accumulation.
boolean	isPeriodic() Returns whether the measurement aggregates every aggregation period (or only over the entire simulation).
String	stringValue(A aggregate, String format) Returns a string representation of the aggregate result.

Method Detail

identity

C identity()

Returns the initial value before accumulation.

Returns:

C; initial value before accumulation

accumulateEntry

C accumulateEntry(C cumulative,
                  LaneBasedGTU gtu,
                  Detector loopDetector)

Returns an accumulated value for when the front reaches the detector.

Parameters:

cumulative - C; accumulated value

gtu - LaneBasedGTU; gtu

loopDetector - LoopDetector; loop detector

Returns:

C; accumulated value

accumulateExit

C accumulateExit(C cumulative,
                 LaneBasedGTU gtu,
                 Detector loopDetector)

Returns an accumulated value for when the rear leaves the detector. GTU's may trigger an exit without having triggered an entry due to a lane change. Reversely, GTU's may not trigger an exit while they did trigger an entry.

Parameters:

cumulative - C; accumulated value

gtu - LaneBasedGTU; gtu

loopDetector - LoopDetector; loop detector

Returns:

C; accumulated value

isPeriodic

boolean isPeriodic()

Returns whether the measurement aggregates every aggregation period (or only over the entire simulation).

Returns:

boolean; whether the measurement aggregates every aggregation period (or only over the entire simulation)

aggregate

A aggregate(C cumulative,
            int count,
            org.djunits.value.vdouble.scalar.Duration aggregation)

Returns an aggregated value.

Parameters:

cumulative - C; accumulated value

count - int; GTU count

aggregation - Duration; aggregation period

Returns:

A; aggregated value

getName

String getName()

Returns the value name.

Returns:

String; value name

stringValue

String stringValue(A aggregate,
                   String format)

Returns a string representation of the aggregate result.

Parameters:

aggregate - A; aggregate result

format - String; format string

Returns:

String; string representation of the aggregate result
