From 7c553e6e5bb47c7b4b26f9bed147e7b7df234f96 Mon Sep 17 00:00:00 2001 From: Dan Winship Date: Thu, 3 May 2001 20:52:59 +0000 Subject: new abstract class for disconnectable remote stores * camel-disco-store.c: new abstract class for disconnectable remote stores * camel-disco-folder.c: new abstract class for folders on disconnectable stores. * Makefile.am: Add camel-disco-folder.[ch] and camel-disco-store.[ch]. * providers/imap/camel-imap-store.c: Make this a subclass of CamelDiscoStore, and fix up the offline interfaces for the changes since they were first written (particularly the fact that some IMAP stores don't just use subscribed folders). * providers/imap/camel-imap-folder.c: Make this a subclass of CamelDiscoFolder, although most ops still fail in disconnected mode. * camel-store.c (camel_store_get_folder_info): Change gboolean, gboolean, gboolean to guint32 in the prototype for this function. * providers/local/camel-local-store.c (get_folder_info): Update for prototype change. svn path=/trunk/; revision=9659 --- camel/camel-disco-folder.c | 243 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 243 insertions(+) create mode 100644 camel/camel-disco-folder.c (limited to 'camel/camel-disco-folder.c') diff --git a/camel/camel-disco-folder.c b/camel/camel-disco-folder.c new file mode 100644 index 0000000000..bce6eaef06 --- /dev/null +++ b/camel/camel-disco-folder.c @@ -0,0 +1,243 @@ +/* -*- Mode: C; tab-width: 8; indent-tabs-mode: t; c-basic-offset: 8 -*- */ +/* camel-disco-folder.c: abstract class for a disconnectable folder */ + +/* + * Authors: Dan Winship + * + * Copyright (C) 2001 Ximian, Inc. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of the + * License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
