public class DemandBasedWaitingTimeCalculator extends WaitingTimeCalculator
Calculates the waiting time for resources in environments where the stop of the waiting period cannot be observed directly. Rather the following values (respectively events) should be observable.
  • start - "request for processing"-event
  • stop - "end of processing"-event (Notice: This is different from the waiting period stop)
  • demand - the demanded time
The waiting time results from calculating (stop - start) - demand . The final result is still a (start point in time, waiting time)-tuple, i.e., a measurement typed with a metric set.

    Modifier and Type
    Method
    Description
    protected org.palladiosimulator.measurementframework.MeasuringValue
    calculate(List<ProbeMeasurement> probeMeasurements)
    Overrides the inherited calculate method because the latter assumed that the stop of the waiting period can directly be obtained.
