A component or deployment diagram may show components or component instances which implement interfaces. For details see Section 18.16, “ Interface ”.
The V0.18 release of ArgoUML uses the same representation of an interface as a class diagram. The UML standard suggests that an interface on a component or deployment diagram should just be shown as a small open circle, connected to the component which realizes that interface.
There is no way to show the linking of an interface to a component or component instance in the V0.18 release of ArgoUML.
