      • distinctCriteria

        public static org.hibernate.Criteria distinctCriteria​(org.hibernate.Session session,
                                                      Class<?> persistentClass)
        Creates a Criteria query for the specified persistent class.
        Parameters:
        session - the Hibernate session
        persistentClass - the class for which to create a criteria query
        Returns:

      • addOrder

        public static org.hibernate.Criteria addOrder​(org.hibernate.Criteria criteria,
                                              String orderClause)
        Adds the specified order clause to an existing Criteria, returning the criteria that was passed in.

        The orderClause should contain a comma-separated list of properties optionally followed by an order designator, which must be asc or desc. If neither ascending nor descending is specified, ascending order is used. For example, the order clause for listing people by descending date of birth, then ascending last name, and finally ascending first name is: 

         dateOfBirth desc, lastName, firstName
        Parameters:
        criteria - an existing Criteria to add ordering to
        orderClause - the order specification
        Returns:
        the same criteria instance passed in, to allow building upon it
