Enhance switch statements

[junghoon-vans]

Traditional switch statements are not very readable. But with Java 17's support for enhanced switch expressions.
it's possible to make them concise and readable. An example is shown below.

AS-IS

private RedisOperationChain from(Part part, Iterator<Object> iterator, RedisOperationChain sink) {

  switch (part.getType()) {
    case SIMPLE_PROPERTY:
      sink.sismember(part.getProperty().toDotPath(), iterator.next());
      break;
    case TRUE:
      sink.sismember(part.getProperty().toDotPath(), true);
      break;
    case FALSE:
      sink.sismember(part.getProperty().toDotPath(), false);
      break;
    case WITHIN:
    case NEAR:
      sink.near(getNearPath(part, iterator));
      break;
    default:
      throw new IllegalArgumentException(String.format("%s is not supported for Redis query derivation", part.getType()));
  }
  
  return sink;
}

TO-BE

private RedisOperationChain from(Part part, Iterator<Object> iterator, RedisOperationChain sink) {

  switch (part.getType()) {
    case SIMPLE_PROPERTY -> sink.sismember(part.getProperty().toDotPath(), iterator.next());
    case TRUE -> sink.sismember(part.getProperty().toDotPath(), true);
    case FALSE -> sink.sismember(part.getProperty().toDotPath(), false);
    case WITHIN, NEAR -> sink.near(getNearPath(part, iterator));
    default -> throw new IllegalArgumentException(
      String.format("%s is not supported for Redis query derivation", part.getType()));
  }
  
  return sink;
}
