```
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.
