Examples of javax.json.JsonReader.readArray()

javax.json.JsonReader.readArray()
Returns a JSON array that is represented in the input source. This method needs to be called only once for a reader instance. @return a Json array @throws JsonException if a JSON array cannotbe created due to i/o error (IOException would be cause of JsonException) @throws JsonParsingException if a JSON array cannotbe created due to incorrect representation @throws IllegalStateException if this method, readObject, readArray orclose method is already called

      String filename = outputdir + "/patterns" + ".json";


      JsonArrayBuilder obj = Json.createArrayBuilder();
      if (writtenPatInJustification.containsKey(label) && writtenPatInJustification.get(label)) {
        JsonReader jsonReader = Json.createReader(new BufferedInputStream(new FileInputStream(filename)));
        JsonArray objarr = jsonReader.readArray();
        jsonReader.close();
        for (JsonValue o : objarr)
          obj.add(o);
      } else
        obj = Json.createArrayBuilder();
