Example 1 with Breadcrumb

use of org.opennms.features.topology.api.support.breadcrumbs.Breadcrumb in project opennms by OpenNMS.

the class BreadcrumbComponent method graphChanged.

@Override
public void graphChanged(GraphContainer graphContainer) {
    final BreadcrumbCriteria criteria = Criteria.getSingleCriteriaForGraphContainer(graphContainer, BreadcrumbCriteria.class, true);
    final HorizontalLayout breadcrumbLayout = (HorizontalLayout) getCompositionRoot();
    breadcrumbLayout.removeAllComponents();
    // Verify that breadcrumbs are enabled
    if (graphContainer.getTopologyServiceClient().getBreadcrumbStrategy() == BreadcrumbStrategy.SHORTEST_PATH_TO_ROOT) {
        final Collection<Vertex> displayVertices = graphContainer.getGraph().getDisplayVertices();
        if (!displayVertices.isEmpty()) {
            final PathTree pathTree = BreadcrumbPathCalculator.findPath(graphContainer.getTopologyServiceClient(), displayVertices.stream().map(v -> (VertexRef) v).collect(Collectors.toSet()));
            final List<Breadcrumb> breadcrumbs = pathTree.toBreadcrumbs();
            criteria.setBreadcrumbs(breadcrumbs);
        }
        for (Breadcrumb eachBreadcrumb : criteria.getBreadcrumbs()) {
            if (breadcrumbLayout.getComponentCount() >= 1) {
                breadcrumbLayout.addComponent(new Label(" > "));
            }

Example 2 with Breadcrumb

use of org.opennms.features.topology.api.support.breadcrumbs.Breadcrumb in project opennms by OpenNMS.

the class PathTree method toBreadcrumbs.

public List<Breadcrumb> toBreadcrumbs() {
    final List<Breadcrumb> breadcrumbList = Lists.newArrayList();
    // Build from bottom to top (including root)
    List<Node> work = getLeafs();
    while (!work.isEmpty() && !work.get(0).isRoot()) {
        // All working nodes must be on the same layer (resulting in the same namespace)
