From dc32c58499caa8b1ec4e975afad75ca0d862e990 Mon Sep 17 00:00:00 2001 From: Tomas Bzatek Date: Sat, 13 Sep 2014 20:37:57 +0200 Subject: Introduce properties table This is a new internal properties storage for attributes that can be defined both in the item and album scope, with the item scope taking priority. The big advantage is a better distinguishment from an undefined, default value. It also makes easier to retrieve attributes with properly defined scope priorities. --- src/properties-table.h | 62 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 src/properties-table.h (limited to 'src/properties-table.h') diff --git a/src/properties-table.h b/src/properties-table.h new file mode 100644 index 0000000..4a1a9ed --- /dev/null +++ b/src/properties-table.h @@ -0,0 +1,62 @@ +/* Cataract - Static web photo gallery generator + * Copyright (C) 2014 Tomas Bzatek + * + * 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 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.
