Event-based API

[d9k]

It would be nice to implement event-based (SAX-style) parser API as in JSR 353 standart:

      String document = "[{\n" + "\"nom\":\"nom1\", \"prenom\": \"prenom1\", \"taille\": 175\n"
              + "},\n"
              + "{\n"
              + "\"nom\": \"nom2\", \"prenom\": \"prenom2\",\"taille\": 183\n" + "}\n"
              + "]";
      try (JsonParser parser = Json.createParser(new StringReader(document))) {
        Event event = null;
        while (parser.hasNext()) {
          event = parser.next();
          System.out.print("event=" + event);
          switch (event) {
            case KEY_NAME:
              System.out.print(" key=" + parser.getString());
              break;
            case VALUE_STRING:
              System.out.print(" value=" + parser.getString());
              break;
            case VALUE_NUMBER:
              if (parser.isIntegralNumber()) {
                System.out.println(" value=" + parser.getInt());
              } else {
                System.out.println(" value=" + parser.getBigDecimal());
              }
              break;
            case VALUE_NULL:
              System.out.print(" value=null");
              break;
          }
          System.out.println("");
        }
      } catch (Exception e) {
        e.printStackTrace();
      }

Event-based parsing will allow to lower memory usage by getting rid of intermediate tree structures and parsing directly to the application/game data structures on the fly.
