Examples of backtype.storm.tuple.Values

backtype.storm.tuple.Values
A convenience class for making tuple values using new Values("field1", 2, 3) syntax.

  public static class Split extends BaseFunction {
    @Override

      String sentence = tuple.getString(0);
      for (String word : sentence.split(" ")) {
        collector.emit(new Values(word));
      }
