Constructor Detail

MeasurementController

public MeasurementController(Set<MeasurementTool> measurementTools)

Constructs a new MeasurementController.

Parameters:

measurementTools - The MeasurementTools to use. Must not be null and must not contain null.

Method Detail

canMeasure

public boolean canMeasure(ReadOnlyMeasurementControllerBlackboardView blackboard)

Determines whether a MeasurementTool can contribute to the Blackboard.

Parameters:

blackboard - The blackboard. Must not be null.

Returns:

Whether a MeasurementTool can measure something which is marked as 'to be measured'. When true is returned, this is no guarantee that at least one new measurement result will be added.

measure

public void measure(MeasurementControllerBlackboardView blackboard)

Instructs all available MeasurementTools to measure all items marked as “to be measured”. MeasurementTools may not produce results for every item but will report results for all items they were able to measure.

This method may only be called, when canMeasure(de.uka.ipd.sdq.beagle.core.measurement.ReadOnlyMeasurementControllerBlackboardView) returned true before and the Blackboard wasn't changed between this call. Otherwise the behaviour of this method is undefined.

Parameters:

blackboard - The blackboard. Must not be null.
