org.eclipse.ui.internal.texteditor.rulers.DAG.addEdge()
Adds a directed edge from origin to target. The vertices are not required to exist prior to this call - if they are not currently contained by the graph, they are automatically added. @param origin the origin vertex of the dependency @param target the target vertex of the dependency @return true if the edge was added, false if theedge was not added because it would have violated the acyclic nature of the receiver.

        if (target == null) {
          noteUnknownTarget(desc, id);
        } else {
          boolean success;
          if (constraint.isBefore())
            success= dag.addEdge(desc, target);
          else
            success= dag.addEdge(target, desc);
          if (!success)
            noteCycle(desc, target);
