The CalendarService interface

Our application contains a CalendarService interface that can be used to access and store our domain objects. The code for CalendarService is as follows:

    //src/main/java/com/packtpub/springsecurity/service/CalendarService.java

    public interface CalendarService {
       CalendarUser getUser(int id);
       CalendarUser findUserByEmail(String email);
       List<CalendarUser> findUsersByEmail(String partialEmail);
       int createUser(CalendarUser user);
       Event getEvent(int eventId);
       int createEvent(Event event);
       List<Event> findForUser(int userId);
       List<Event> getEvents();
    }

We won't go over the methods used in CalendarService, but they should be fairly straightforward. If you would like details about what each method does, please consult the Javadoc in the sample code.
