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.
