From e452707fdfbd61be1e5633b516b653b7337e7865 Mon Sep 17 00:00:00 2001 From: Christian Mollekopf Date: Mon, 29 May 2017 16:17:04 +0200 Subject: Reduced the messagetreeparser to aproximately what we actually require While in a much more managable state it's still not pretty. However, further refactoring can now gradually happen as we need to do further work on it. Things that should happen eventually: * Simplify the logic that creates the messageparts (we don't need the whole formatter plugin complexity) * Get rid of the nodehelper (let the parts hold the necessary data) * Get rid of partmetadata (let the part handleit) --- .../bodypartformatterbasefactory.cpp | 179 +++++++++++++++++++++ 1 file changed, 179 insertions(+) create mode 100644 framework/src/domain/mime/mimetreeparser/bodypartformatterbasefactory.cpp (limited to 'framework/src/domain/mime/mimetreeparser/bodypartformatterbasefactory.cpp') diff --git a/framework/src/domain/mime/mimetreeparser/bodypartformatterbasefactory.cpp b/framework/src/domain/mime/mimetreeparser/bodypartformatterbasefactory.cpp new file mode 100644 index 00000000..fb02945b --- /dev/null +++ b/framework/src/domain/mime/mimetreeparser/bodypartformatterbasefactory.cpp @@ -0,0 +1,179 @@ +/* + bodypartformatterfactory.cpp + + This file is part of KMail, the KDE mail client. + Copyright (c) 2004 Marc Mutz , + Ingo Kloecker + + KMail 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. + + KMail 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.
