Class SlidingWindowRecorder

java.lang.Object

org.palladiosimulator.recorderframework.AbstractRecorder

org.palladiosimulator.experimentanalysis.SlidingWindowRecorder

All Implemented Interfaces:

org.palladiosimulator.measurementframework.listener.IMeasurementSourceListener, org.palladiosimulator.recorderframework.IRecorder

public class SlidingWindowRecorder
extends org.palladiosimulator.recorderframework.AbstractRecorder

This class implements a Recorder which writes incoming data into a sliding window rather than passing it on to a persistence framework like EDP2.

Constructor Detail

SlidingWindowRecorder

public SlidingWindowRecorder(SlidingWindow slidingWindow,
                             java.lang.Iterable<ISlidingWindowListener> listeners)

Initializes a new instance of the SlidingWindowRecorder class with the given parameters.

Parameters:

slidingWindow - SlidingWindow to write incoming measurements into.

listeners - A collection of ISlidingWindowListeners, typically SlidingWindowAggregators, that will be attached to the given window ( null is okay).

Throws:

java.lang.IllegalArgumentException - If the given window is null.

SlidingWindowRecorder

public SlidingWindowRecorder(SlidingWindow slidingWindow,
                             ISlidingWindowListener listener)

Initializes a new instance of the SlidingWindowRecorder class with the given parameters.

Parameters:

slidingWindow - SlidingWindow to write incoming measurements into.

listener - A ISlidingWindowListener, typically a SlidingWindowAggregator, that will be attached to the given window.

Throws:

java.lang.IllegalArgumentException - If the given window is null.

Method Detail

initialize

public void initialize(org.palladiosimulator.recorderframework.config.IRecorderConfiguration recorderConfiguration)

This implementation does nothing.

writeData

public void writeData(org.palladiosimulator.measurementframework.MeasuringValue measurement)

That is, the given measurement is written into the associated SlidingWindow.

Throws:

java.lang.IllegalArgumentException - If the given measurement is null or does not adhere to the metric the associated window accepts.

java.lang.IllegalStateException - If this window is not initialized, i.e., SlidingWindow#initialize(SimuComModel) has not been called beforehand.

flush

public void flush()

It has the corresponding SlidingWindow instance discard the collected data.
