Pinaki,
My makeOrderList() method looks like this:
private List<Order> makeOrderList(
CriteriaBuilder builder,
Root<E> root,
SingularAttribute<E, ?>[] pOrderFields
) {
List<Order> orderList = new LinkedList<>();
for (SingularAttribute<E, ?> attribute: pOrderFields) {
orderList.add(builder.asc(root.get(attribute)));
}
return orderList;
}
I don't know how to specify an order without using the root to get the
attribute. Am I doing something wrong in this method?
