Getting Started with pureQuery
application. After an implementation class has been generated for an interface, you can
create an instance of the interface using DataFactory (which actually creates an instance of
the generated implementation class whose name ends in “...Impl”) and run its methods, as
shown in Listing 11.2.
DepartmentData data = DataFactory.getData (DepartmentData.class,
connection);
List allDepartments = data.selectAllDepartments());
// Iterate through the departments
DepartmentBean department = data.selectDepartmentByNumber
(departmentNumber);
// Do something with the department

SQL statements
Figure 11.1 shows how you can create an instance of a user-defined interface.
