| /** |
| * This interface defines a visual component which may serve text viewers as an annotation presentation |
| * area. Implementers of this interface have to define the presentation modus. This can either depend |
| * on the connected viewer's view port or not. If the modus is view port dependent the ruler only shows |
| * those annotations that are attached to document regions that are visible in the view port. If independent, |
| * the presented annotations can also be attached to invisible document regions. |
| * |
| * This interfaces comprises three contracts: |
| * <ul> |
| * <li> The vertical ruler retrieves the annotations it presents from an annotation model. |
| * <li> The ruler is a visual component which must be integrated in a hierarchy of SWT controls. |
| * <li> The ruler provides interested clients with mapping and |
| * interaction information. This covers the mapping between |
| * coordinates of the ruler's control and line numbers based |
| * on the connected text viewer's document (<code>IVerticalRulerInfo</code>). |
| * </ul> |
| * Clients may implement this interface or use the default implementation provided |
| * by <code>CompositeRuler</code> and <code>VerticalRuler</code>. |
