public class SimulationTimePowerCalculator
extends org.palladiosimulator.measurementframework.listener.MeasurementSource
implements ISimulationEvaluationScopeListener

Implementation of a MeasurementSource which uses measurements provided by a SimulationTimeEvaluationScope to compute the power consumption of a PowerProvidingEntity at simulation-time.

Constructor Summary

Constructors

Constructor	Description
SimulationTimePowerCalculator(de.fzi.power.interpreter.ConsumptionContext consumptionContext, SimulationTimeEvaluationScope scope, de.fzi.power.infrastructure.PowerProvidingEntity ppe)	Initializes a new instance of the SimulationTimePowerCalculator class with the given arguments.

Method Summary

Modifier and Type	Method	Description
void	newElementAvailable()	An observed SimulationTimeEvaluationScope invokes this callback method once a new measurement has been collected.
void	preUnregister()	If the observed scope is about to detach an observer (e.g., due to a call of SimulationTimeEvaluationScope.removeAllListeners() or SimulationTimeEvaluationScope.removeListener(ISimulationEvaluationScopeListener)), this callback method is invoked.

Constructor Detail

SimulationTimePowerCalculator

public SimulationTimePowerCalculator(de.fzi.power.interpreter.ConsumptionContext consumptionContext,
                                     SimulationTimeEvaluationScope scope,
                                     de.fzi.power.infrastructure.PowerProvidingEntity ppe)

Initializes a new instance of the SimulationTimePowerCalculator class with the given arguments.

Parameters:

consumptionContext - The ConsumptionContext used for evaluating the power consumption.

scope - The SimulationTimeEvaluationScope this instance will observe.

ppe - The PowerProvidingEntity whose consumption is to be calculated.

Throws:

NullPointerException - In case any of the arguments is null.

Method Detail

newElementAvailable

public void newElementAvailable()

An observed SimulationTimeEvaluationScope invokes this callback method once a new measurement has been collected. The new measurement can be retrieved by means of the scope's AbstractEvaluationScope.next() method or by using the scope's iterator.

This implementation obtains a new power consumption measurement based on the new measurement provided by the evaluation scope and forwards it to all attached listeners.

Specified by:

newElementAvailable in interface ISimulationEvaluationScopeListener

preUnregister

public void preUnregister()

Description copied from interface: ISimulationEvaluationScopeListener

If the observed scope is about to detach an observer (e.g., due to a call of SimulationTimeEvaluationScope.removeAllListeners() or SimulationTimeEvaluationScope.removeListener(ISimulationEvaluationScopeListener)), this callback method is invoked.

Specified by:

preUnregister in interface ISimulationEvaluationScopeListener
