From 971c02f3707c4872a2da9a3b946b6508290c5ab4 Mon Sep 17 00:00:00 2001 From: David Robillard Date: Sun, 7 Oct 2007 23:09:48 +0000 Subject: Added shared abstract interface for ports. Moved DataType to shared. Switch data type URIs to match LV2 type semantics (e.g. separate audio/control types). git-svn-id: http://svn.drobilla.net/lad/ingen@840 a436a847-0d15-0410-975c-d299462d15a1 --- src/common/interface/DataType.hpp | 86 +++++++++++++++++++++++++++++++++++++++ src/common/interface/Makefile.am | 6 ++- src/common/interface/Node.hpp | 11 ++--- src/common/interface/Port.hpp | 47 +++++++++++++++++++++ 4 files changed, 144 insertions(+), 6 deletions(-) create mode 100644 src/common/interface/DataType.hpp create mode 100644 src/common/interface/Port.hpp (limited to 'src/common/interface') diff --git a/src/common/interface/DataType.hpp b/src/common/interface/DataType.hpp new file mode 100644 index 00000000..a2e3ce5a --- /dev/null +++ b/src/common/interface/DataType.hpp @@ -0,0 +1,86 @@ +/* This file is part of Ingen. + * Copyright (C) 2007 Dave Robillard + * + * Ingen 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. + * + * Ingen 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.
