Sounds to me like PoweredDevice would be an interface.
- rahkiin 10y agoOr an IScannable and IPrintable interface (that is not the correct english word for 'something that can scan'..), and a Scanner implementing IScannable and deriving from PoweredDevice. And a copier deriving from PoweredDevice implementing both interfaces. Then an interface is a capability.
