From 99454be38cf1dc7f962441d23ccc0a59e7b05f3d Mon Sep 17 00:00:00 2001 From: Evan Prodromou Date: Sat, 20 Mar 2010 16:06:22 -0500 Subject: Move activity classes to their own files Moved the various classes used by the Activity class to their own files. There were >10 classes in the same file, with around 1500 lines in the file. Just too big. This change makes autoloading work for these classes, so also removed the hard require in lib/common.php. --- lib/activityobject.php | 494 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 494 insertions(+) create mode 100644 lib/activityobject.php (limited to 'lib/activityobject.php') diff --git a/lib/activityobject.php b/lib/activityobject.php new file mode 100644 index 000000000..b1e9071ed --- /dev/null +++ b/lib/activityobject.php @@ -0,0 +1,494 @@ +. + * + * @category Feed + * @package StatusNet + * @author Evan Prodromou + * @author Zach Copley + * @copyright 2010 StatusNet, Inc. + * @license http://www.fsf.org/licensing/licenses/agpl-3.0.html AGPLv3 + * @link http://status.net/ + */ + +if (!defined('STATUSNET')) { + exit(1); +} + +/** + * A noun-ish thing in the activity universe + * + * The activity streams spec talks about activity objects, while also having + * a tag activity:object, which is in fact an activity object.
