```
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.

```
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 Detail
  - 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.
