Examples with FlowEdge org.eclipse.n4js.flowgraphs.FlowEdge used on opensource projects

Example 1 with FlowEdge

use of org.eclipse.n4js.flowgraphs.FlowEdge in project n4js by eclipse.

the class PathWalkerGuide method visitNode.

@Override
public void visitNode(Node node) {
    if (node instanceof RepresentingNode) {
        ControlFlowElement cfeEnd = node.getRepresentedControlFlowElement();
        if (lastVisitedNode != null) {
            ControlFlowElement cfeStart = lastVisitedNode.getRepresentedControlFlowElement();
            FlowEdge edge = new FlowEdge(cfeStart, cfeEnd, cfTypes);
            walker.visit(edge);
        }
        cfTypes.clear();
        walker.visit(cfeEnd);
        lastVisitedNode = node;
    }
}

Example 2 with FlowEdge

use of org.eclipse.n4js.flowgraphs.FlowEdge in project n4js by eclipse.

the class BranchWalker method visit.

@Override

    pEdgeTypes.add(edge.cfType);
    if (end instanceof RepresentingNode || this.getContainer() == end.getControlFlowElement()) {

            startCFE = startCFE == null ? lastRN.getControlFlowElement() : startCFE;
            FlowEdge flowEdge = new FlowEdge(startCFE, endCFE, pEdgeTypes);
            visit(flowEdge);
            pEdgeTypes.clear();
        } else {
