| * A service which can appear on a component which is wholly contained with |
| * another component. The component on which it appears can be active or |
| * inactive -- depending on the state of the application. For example, a |
| * workbench part is a component which appears within a workbench window. This |
| * workbench part can either be active or inactive, depending on what the user |
| * is doing. |
| * </p> |
| * <p> |
| * Services implement this interface, and are then notified by the component |
| * when the activation changes. It is the responsibility of the component to |
| * notify such services when the activation changes. |
