Class CurrentTimeEventGenerator

java.lang.Object
  kieker.tools.currentTimeEventGenerator.CurrentTimeEventGenerator

public class CurrentTimeEventGenerator
extends Object

Generates time events with a given resolution based on the timestamps of incoming IMonitoringRecords.

1. The first record received via newTimestamp(long) immediately leads to a new TimestampEvent with the given timestamp.
2. The timestamp of the first record is stored as firstTimestamp and future events are generated at firstTimestamp + i * timerResolution.
3. Future IMonitoringRecord may lead to future TimestampEvent as follows:
   1. A newly incoming IMonitoringRecord with logging timestamp tstamp leads to the new timer events satisfying firstTimestamp + i * timerResolution < tstamp.

It is guaranteed that the generated timestamps are in ascending order.
