Use ical_object_to_string().
2000-03-27 Federico Mena Quintero <federico@helixcode.com> * pcs/cal-backend.c (cal_backend_get_object): Use ical_object_to_string(). * cal-util/calobj.c (ical_object_to_string): Moved over from pcs/cal-backend.c (was string_from_ical_object). (get_calendar_base_vobject): Likewise, moved over from pcs/cal-backend.c. * cal-util/cal-util.c: Removed string_to_ical_object(); the correct function is in calobj.[ch], called ical_object_find_in_string(). Removed ical_object_to_string, since we now implement it in calobj.c. * cal-util/calobj.c: Removed ical_object_new_from_string(); see above. * idl/evolution-calendar.idl (CalObjInstance): Calendar object instances now contain only the UID for the object, not the whole string representation of the object. This allows clients to implement caching of objects if they wish. * pcs/cal.c (Cal_get_events_in_range): Likewise. * pcs/cal-backend.c (build_event_list): Likewise. * cal-client/cal-client.c (cal_client_get_events_in_range): Likewise. * cal-util/cal-util.h (CalObjInstance): Likewise. * cal-util/cal-util.c (cal_obj_instance_list_free): Likewise. (cal_obj_uid_list_free): Assert that the UIDs in the list are not NULL. * pcs/tlacuache.gnorba (repo_id): The calendar factory also supports the Unknown interface. svn path=/trunk/; revision=2211
