Replace struct icalattachtype by an opaque icalattach that is properly
2001-09-10 Federico Mena Quintero <federico@ximian.com> Replace struct icalattachtype by an opaque icalattach that is properly reference-counted. * src/libical/icalvalueimpl.h (struct icalattach_impl): Private declaration for the icalattach type. (struct icalvalue_impl): Make the v_attach field be an icalattach *. * src/libical/icaltypes.h: Added declaration for icalattach. This is now an opaque type; the implementation is in icalvalueimpl.h. (struct icalattachtype): Removed. * src/libical/icaltypes.c (icalattach_new_from_url): New function. (icalattach_new_from_data): New function. (icalattach_ref): New function. (icalattach_unref): New function. (icalattach_get_is_url): New function. (icalattach_get_url): New function. (icalattach_get_data): New function. (icalattachtype_new): Removed. (icalattachtype_free): Removed. (icalattachtype_add_reference): Removed. (icalattachtype_set_url): Removed. (icalattachtype_get_url): Removed. (icalattachtype_set_base64): Removed. (icalattachtype_get_base64): Removed. (icalattachtype_set_binary): Removed. (icalattachtype_get_binary): Removed. * src/libical/icalderivedvalue.c.in (icalvalue_new_attach): New function; we implement it ourselves. (icalvalue_set_attach): New function. (icalvalue_get_attach): New function. * src/libical/icalvalue.c (icalmemory_strdup_and_dequote): Made static. (icalvalue_new_clone): Clone BINARY and ATTACH values by refing the old attach value. (icalvalue_free): Free BINARY and ATTACH values. (icalvalue_attach_as_ical_string): Handle the new icalattachtype. (icalvalue_compare): Ditto. * src/libical/Makefile.am (CLEANFILES): Added ical.h. * design-data/*: Mark ATTACH as a custom value. svn path=/trunk/; revision=12745
