public final class EvaluationScope
extends AbstractEvaluationScope

This class represents the scope under which the energy consumption of a software system is evaluated. It subsumes a set of measurements or probes on the measurement. Specifically, a set of MetricDescriptionConstants.STATE_OF_ACTIVE_RESOURCE_METRIC_TUPLE on resources is translated into a set of discrete evaluations on the utilization.

Method Detail

createScope

public static EvaluationScope createScope(Iterable<org.palladiosimulator.edp2.datastream.IDataSource> experimentMeasurements,
                                          Collection<ExtendedMeasureProvider> extendedMeasureProviders)

Creates an evaluation scope for which the energy consumption of a software system is evaluated. The scope is created for a set of available experimentMeasures.

Parameters:

experimentMeasurements - set of measurement sources each collected on an active resource within the system.

extendedMeasureProviders - collection of extended measurement providers, allowing to derive one metric from another (e.g. MetricDescriptionConstants.UTILIZATION_TUPLE measurements from MetricDescriptionConstants.STATE_OF_ACTIVE_RESOURCE_TUPLE measurements)

Returns:

The created scope representing the context for the energy consumption evaluation.

Throws:

NullPointerException - In case either of the arguments is null.

reset

public void reset()

Resets the context to its initial state.

Overrides:

reset in class AbstractEvaluationScope

setResourceMetricsToEvaluate

public void setResourceMetricsToEvaluate(Map<org.palladiosimulator.pcm.resourceenvironment.ProcessingResourceSpecification,Set<org.palladiosimulator.metricspec.MetricDescription>> metricsMap)

Description copied from class: AbstractEvaluationScope

Sets for each ProcessingResourceSpecification which metrics are supposed to be evaluated. The method is to be provided by implementing subclasses.
A call to this method results in initializing the resourceMeasurements used to when iterating the scope. If for a certain ProcessingResourceSpecification and MetricDescription there are no measurements available or there is no way to create the measurements from the available data, an IllegalArgumentException is thrown.

Specified by:

setResourceMetricsToEvaluate in class AbstractEvaluationScope

Parameters:

metricsMap - the Map linking ProcessingResourceSpecifications to the metrics needed by the AbstractResourcePowerModelCalculator in use.
