public class ExampleTakeCPUDemandProbe
extends BasicEventProbe<ASimpleActiveResource,Double,javax.measure.quantity.Duration>
implements Observer

Measures a resource demand metric (in SI.SECOND) by taking the demand emitted from an active resource (event source), e.g., a CPU. This class uses ASimpleActiveResource as an example active resource.

Constructor Details

ExampleTakeCPUDemandProbe

public ExampleTakeCPUDemandProbe(ASimpleActiveResource activeResource)

Default constructor.

Parameters:

activeResource - The event source is an active resource (e.g., a CPU), thus, able to emit demand events.

Method Details

registerListener

protected void registerListener()

Template method for registering observers to the event source.

Specified by:

registerListener in class EventProbe<ASimpleActiveResource>

update

public void update(Observable eventSource,
 Object event)

Receives a new demand event from the active resource (event source). Afterwards, notifies all observers about this new measurement.

Specified by:

update in interface Observer

Parameters:

eventSource - The observed event source.

event - The emitted event, including the demand measurement.
