Package org.palladiosimulator.measurementframework.listener

Class MeasurementSource

java.lang.Object

org.palladiosimulator.metricspec.metricentity.MetricEntity

org.palladiosimulator.measurementframework.listener.MeasurementSource

All Implemented Interfaces:

org.palladiosimulator.commons.designpatterns.IAbstractObservable<IMeasurementSourceListener>, org.palladiosimulator.metricspec.metricentity.IMetricEntity

public abstract class MeasurementSource
extends org.palladiosimulator.metricspec.metricentity.MetricEntity
implements org.palladiosimulator.commons.designpatterns.IAbstractObservable<IMeasurementSourceListener>

AbstractMeasureProvider sources provide measurements from analyzers, e.g., by providing the measurements from probes. To provide such measurements, they implement the observer pattern. Observers have to implement the IMeasurementSourceListener interface to get informed about new measurements.
