Criteria query to load rows for a class type which is not mapped to a single table/entity in Hibernate

Issue

Load arbitrary "tuples" from entity class properties into a custom "tuple" class using a criteria query given the following:

public static class EmpDepTuple { // custom non-entity tuple class
        private String emp, dep;

        public EmpDepTuple(String emp, String dep) {
                this.emp = emp;
                this.dep = dep;
        }

        public String getEmp() {
                return emp;
        }

        public String getDep() {
                return dep;
        }
}

@Entity
public class Department {
        private String name;
}

@Entity
public class Employee {
        private String name;
        private Department department;
}
