Class RealtimeRecordDelayProducer

java.lang.Object

teetime.framework.AbstractStage

teetime.framework.AbstractProducerStage<IMonitoringRecord>

kieker.analysisteetime.plugin.filter.record.delayfilter.components.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.

Constructor Detail

RealtimeRecordDelayProducer

public RealtimeRecordDelayProducer(java.util.concurrent.LinkedBlockingQueue<java.lang.Object> recordQueue,
                                   java.lang.Object endToken,
                                   java.util.concurrent.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.

Method Detail

execute

protected void execute()

Specified by:

execute in class teetime.framework.AbstractStage

getNegativeDelayWarningBound

public long getNegativeDelayWarningBound()

Returns the time bound for which a warning is displayed when the computed delay falls below -(time bound).

Returns:

negativeDelayWarningBound

setNegativeDelayWarningBound

public void setNegativeDelayWarningBound(long negativeDelay,
                                         java.util.concurrent.TimeUnit unit)

Sets the time bound for which a warning is displayed when the computed delay falls below -(time bound).

Parameters:

negativeDelay - The chosen time bound.

unit - Time unit of the chosen time bound.
