2000-08-08 Federico Mena Quintero <federico@helixcode.com> * idl/evolution-calendar.idl (Cal): Added a get_objects_in_range() method. Takes in a time range and the type of component we are interested in; returns a list of UIDs. The idea is that ocurrences get computed in the client; we can have multiple recurrences in iCalendar and we cannot identify them trivially across the wire. (Cal): Removed the get_events_in_range() method. * pcs/cal-backend.c (cal_backend_free_uid_list): New function. (cal_backend_get_objects_in_range): New function. (cal_backend_get_events_in_range): Removed. * pcs/cal-backend-file.c (cal_backend_file_get_objects_in_range): Implemented new method. (cal_backend_file_get_events_in_range): Removed. * pcs/cal.c (Cal_get_events_in_range): Removed. (uncorba_obj_type): New function. (Cal_get_uids): Use uncorba_obj_type(). (Cal_get_n_objects): Likewise. (Cal_get_objects_in_range): Implemented new method. * cal-client/cal-client.c (cal_client_get_events_in_range): Removed. (cal_client_get_objects_in_range): Implemented. (corba_obj_type): New function. (cal_client_get_n_objects): Use corba_obj_type(). (cal_client_get_uids): Likewise. svn path=/trunk/; revision=4613
