| * An interface for an adaptable object. |

| * Adaptable objects can be dynamically extended to provide different |
| * interfaces (or "adapters"). Adapters are created by adapter |
| * factories, which are in turn managed by type by adapter managers. |
| * </p> |
| * For example, |
| * <pre> |
| * IAdaptable a = [some adaptable]; |
| * IFoo x = (IFoo)a.getAdapter(IFoo.class); |
| * if (x != null) |
| * [do IFoo things with x] |
| * </pre> |
| * <p> |
| * Clients may implement this interface. |
