| * A source presentation is used to resolve an editor in |
| * which to display a debug model element, breakpoint, or |
| * source element. By default, a debug model presentation |
| * (which implements this interface) is used to resolve |
| * editors when performing source lookup. However, a source |
| * locator may override default editor resolution by implementing |
| * this interface. |
| * <p> |
| * Source lookup consists of the following steps:<ol> |
| * <li>Locating a source element - the source locator associated |
| * with a launch is queried for the source element associated |
| * with a stack frame.</li> |
| * <li>Resolving an editor in which to display a source element - |
| * by default, the debug model presentation associated with the |
| * debug model being debugged is queried for an editor input |
| * and editor id in which to display a source element. However, |
| * clients may override editor resolution by specifying a source |
| * locator that is an instance of <code>ISourcePresentation</code>. |
| * When a source presentation is specified as a source locator, |
| * the source presentation is used to resolve an editor, rather |
| * than the default debug model presentation.</li> |
| * </ol> |
| * </p> |
| * <p> |
| * Clients may implement this interface as part of an |
| * {@link org.eclipse.debug.ui.IDebugModelPresentation} or as an optional |
| * extension to an {@link org.eclipse.debug.core.model.ISourceLocator}. |
