makeOrders

public static List<Order> makeOrders(Props table,
 String... codes)

Parse dynamic code to jimmer order list, For example:

 q.makeOrders(
     Order.orders(
         table,
         "name asc, parent.name desc nulls last"
         "edition desc",
         "region.segment.size; region.segment.cost desc"
     )
 )
 

makeCustomOrders

public static <O> List<O> makeCustomOrders(Order.CustomOrderCreator<O> creator,
 String... codes)

Parse dynamic code to order list of third-party library, such as `Sort.Order` of spring-data, For example: cast to list whose element type is `Sort.Order` of spring data

 List<Sort.Order> orders =
     Order.makeCustomOrders(
         (path, orderMode, nullOrderMode) -> {
             NullHandling nullHandling;
             switch (nullOrderMode) {
                 case NullOrderMode.NULLS_FIRST:
                     nullHandling = NullHandling.NULLS_FIRST;
                     break;
                 case NullOrderMode.NULLS_LAST:
                     nullHandling = NullHandling.NULLS_LAST;
                     break;
                 default:
                     nullHandling = NullHandling.NATIVE;
                     break;
             }
             return new Sort.Order(
                 path,
                 orderMode == OrderMode.DESC ? Direction.DESC : Direction.ASC,
                 nullHandling
             );
         },
         "name asc, parent.name desc nulls last"
         "edition desc",
         "region.segment.size; region.segment.cost desc"
     )
