QueryResultsUtilities

The QueryResultsUtilities class allows to parse the XML and create an associated data structure which can be processed.

The various methods of this class will return a QueryResults instance which will hold the results.

Example

Suppose the following query:

   SELECT ?number ?type
   WHERE { 
      ?alarm rdf:type inav:Alarm .
      ?alarm inav:AlarmNumber ?number .
      ?alarm inav:hasAlarmType ?type .
   }    

The following code will print the ?number and ?type of each result:

   public void subscribe(ServiceInstance service) {
      QueryResults results = (QueryResults) service.getData("response").getValue();
      Iterator<QueryResults.Result> it = results.getOrderedResultsList().iterator();
      while (it.hasNext()) {
       QueryResults.Result result = it.next();
        int number = result.getValue("number").getValueAsInt();
        String type = result.getValue("type").getValueAsString();
        System.out.println("Alarm " + number + ": " + type);
      }
   }
