teetime.framework.AbstractProducerStage<IMonitoringRecord>
kieker.analysis.generic.RealtimeRecordDelayProducer
public class RealtimeRecordDelayProducer extends teetime.framework.AbstractProducerStage<IMonitoringRecord>
Gets records from a queue, calculates the delay for each records and forwards the records after the delay. As this stage extends AbstractProducerStage it is always declared as active.

      public RealtimeRecordDelayProducer(LinkedBlockingQueue<Object> recordQueue, Object endToken, TimeUnit timeunit, double accelerationFactor)
      Creates a new instance of this class using the given parameters.
      Parameters:
      recordQueue - Queue to pass records from RealtimeRecordDelayConsumer to RealtimeRecordDelayProducer.
      endToken - Simple Object to indicate that no more records are received and the stage can terminate.
      timeunit - The time unit to be used.
      accelerationFactor - Determines the replay speed.
