Class AbstractCurrentTimeEventGenerationFilter<T>

java.lang.Object
teetime.framework.AbstractStage
teetime.framework.AbstractConsumerStage<T>
kieker.analysis.generic.time.AbstractCurrentTimeEventGenerationFilter<T>
Type Parameters:
T - Type parameter for this abstract class concrete implementations may use Long or IMonitoringRecord.
Direct Known Subclasses:
RecordCurrentTimeEventGenerationFilter, TimestampCurrentTimeEventGenerationFilter
public abstract class AbstractCurrentTimeEventGenerationFilter<T>
extends teetime.framework.AbstractConsumerStage<T>
Generates time events with a given resolution based on the timestamps of incoming IMonitoringRecords.
  1. The first record received immediately leads to a new TimestampRecord 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 TimestampRecord 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.
