Examples with Abstraction org.batfish.symbolic.abstraction.Abstraction used on opensource projects

Example 1 with Abstraction

use of org.batfish.symbolic.abstraction.Abstraction in project batfish by batfish.

the class PropertyChecker method findAllNetworkSlices.

private Tuple<Stream<Supplier<NetworkSlice>>, Long> findAllNetworkSlices(HeaderQuestion q, @Nullable Graph graph, boolean useDefaultCase) {
    if (q.getUseAbstraction()) {
        HeaderSpace h = q.getHeaderSpace();
        int numFailures = q.getFailures();
        System.out.println("Start verification");
        System.out.println("Using headerspace: " + h.getDstIps());
        DestinationClasses dcs = DestinationClasses.create(_batfish, graph, h, useDefaultCase);
        System.out.println("Number of edges: " + dcs.getGraph().getAllRealEdges().size());
        System.out.println("Created destination classes");
        System.out.println("Num Classes: " + dcs.getHeaderspaceMap().size());
        long l = System.currentTimeMillis();
        ArrayList<Supplier<NetworkSlice>> ecs = NetworkSlice.allSlices(dcs, numFailures);
        l = System.currentTimeMillis() - l;
        System.out.println("Created BDDs");
        return new Tuple<>(ecs.parallelStream(), l);
    } else {
        List<Supplier<NetworkSlice>> singleEc = new ArrayList<>();
        Graph g = graph == null ? new Graph(_batfish) : graph;
        Abstraction a = new Abstraction(g, null);
        NetworkSlice slice = new NetworkSlice(q.getHeaderSpace(), a, false);
