From 76dac45ebaf104b312a8527a05424601ca9d520a Mon Sep 17 00:00:00 2001 From: ewinslow Date: Mon, 6 Sep 2010 02:42:09 +0000 Subject: Refs #2220: Pulled most classes / interfaces out of lib files (except query.php and exception.php) into "classes" folder. Replaced inline classes with "require_once" statements for now. Ran unit tests to verify functionality before committing. git-svn-id: http://code.elgg.org/elgg/trunk@6908 36083f99-b078-4883-b0ff-0f9b5a30f544 --- engine/classes/ElggObject.php | 199 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 199 insertions(+) create mode 100644 engine/classes/ElggObject.php (limited to 'engine/classes/ElggObject.php') diff --git a/engine/classes/ElggObject.php b/engine/classes/ElggObject.php new file mode 100644 index 000000000..af67ef3f6 --- /dev/null +++ b/engine/classes/ElggObject.php @@ -0,0 +1,199 @@ +attributes['type'] = "object"; + $this->attributes['title'] = ""; + $this->attributes['description'] = ""; + $this->attributes['tables_split'] = 2; + } + + /** + * Construct a new object entity, optionally from a given id value. + * + * @param mixed $guid If an int, load that GUID. + * If a db row then will attempt to load the rest of the data. + * @throws Exception if there was a problem creating the object. + */ + function __construct($guid = null) { + $this->initialise_attributes(); + + if (!empty($guid)) { + // Is $guid is a DB row - either a entity row, or a object table row. + if ($guid instanceof stdClass) { + // Load the rest + if (!$this->load($guid->guid)) { + throw new IOException(sprintf(elgg_echo('IOException:FailedToLoadGUID'), get_class(), $guid->guid)); + } + } + + // Is $guid is an ElggObject?
