Annotation Type OrderBy

@Target(value={FIELD,METHOD})
@Retention(value=RUNTIME)
public @interface OrderBy

Specifies the ordering of the elements of a collection valued association at the point when the association is retrieved.

The syntax of the value ordering element is an orderby_list, as follows:

 orderby_list::= orderby_item [,orderby_item]*
 orderby_item::= property_or_field_name [ASC | DESC]
 

If ASC or DESC is not specified, ASC (ascending order) is assumed.

If the ordering element is not specified, ordering by the primary key of the associated entity is assumed. The property or field name must correspond to that of a persistent property or field of the associated class. The properties or fields used in the ordering must correspond to columns for which comparison operators are supported.
