    ic.getConstraintsConverter().register(new ScheduleConverter());
    ReconfigurationPlanConverter pc = new ReconfigurationPlanConverter();
    JSONObject o = new JSONObject();
    o.put("constraint", constraint().id());
    JSONArray a = new JSONArray();
    for (Constant c : args()) {
        a.add(c.toJSON());
    }
    o.put("args", a);
    o.put("continuous", continuous());
    o.put("groups", groups());
    o.put("plan", pc.toJSON(plan()));

Example 2 with InstanceConverter

use of org.btrplace.json.model.InstanceConverter in project scheduler by btrplace.

public static TestCase fromJSON(List<Constraint> cstrs, String c) throws ParseException, JSONConverterException {
    JSONParser p = new JSONParser(JSONParser.MODE_RFC4627);
    JSONObject o = (JSONObject) p.parse(new StringReader(c));
    String cId = o.getAsString("constraint");
    Optional<Constraint> opt = cstrs.stream().filter(x -> x.id().equals(cId)).findFirst();
    if (!opt.isPresent()) {
        throw new IllegalArgumentException("Unknown constraint '" + cId + "'");
    }
    Constraint cstr = opt.get();
    InstanceConverter ic = new InstanceConverter();
    ic.getConstraintsConverter().register(new ScheduleConverter());
    ReconfigurationPlanConverter rc = new ReconfigurationPlanConverter();
    Instance i = ic.fromJSON(o.getAsString("instance"));
    ReconfigurationPlan plan = rc.fromJSON(o.getAsString("plan"));
    TestCase tc = new TestCase(i, plan, cstr);
    List<Constant> l = new ArrayList<>();
    for (Object x : (JSONArray) o.get("args")) {
        l.add(Constant.fromJSON((JSONObject) x));
    }
    tc.args(l);
    if (cstr.isSatConstraint()) {
        tc.impl(cstr.instantiate(l.stream().map(x -> x.eval(null)).collect(Collectors.toList())));
    }
    if (tc.impl() != null) {
        tc.impl().setContinuous((Boolean) o.get("continuous"));
    }
    return tc;
}
