Class ConfidenceStopCondition

java.lang.Object

de.uka.ipd.sdq.simucomframework.stopcondition.ConfidenceStopCondition

All Implemented Interfaces:

SimCondition, org.palladiosimulator.measurementframework.listener.IMeasurementSourceListener

public class ConfidenceStopCondition
extends Object
implements SimCondition, org.palladiosimulator.measurementframework.listener.IMeasurementSourceListener

ConfidenceStopCondition

public ConfidenceStopCondition(SimuComModel model,
                               de.uka.ipd.sdq.statistics.IBatchAlgorithm batchAlgorithm,
                               de.uka.ipd.sdq.statistics.estimation.IConfidenceEstimator estimator,
                               double confidenceLevel,
                               double halfWidth)

Parameters:

model -

batchAlgorithm -

confidenceLevel - the confidence level. Use values between 0 and 1.

halfWidth - the relative half width of the target confidence interval. Use values between 0 and 1.

Method Detail

check

public boolean check()

Description copied from interface: SimCondition

Checks whether this condition is satisfied. This is the case, for instance, if a certain stopping criterion holds.

Specified by:

check in interface SimCondition

Returns:

true, if the condition is satisfied; false, else.

newMeasurementAvailable

public void newMeasurementAvailable(org.palladiosimulator.measurementframework.MeasuringValue resultTuple)

Specified by:

newMeasurementAvailable in interface org.palladiosimulator.measurementframework.listener.IMeasurementSourceListener

getConfidence

public de.uka.ipd.sdq.statistics.estimation.ConfidenceInterval getConfidence()

preUnregister

public void preUnregister()

Specified by:
