6 | * The parent class for all Elgg Entities. |
||||
7 | * |
||||
8 | * An \ElggEntity is one of the basic data models in Elgg. |
||||
9 | * It is the primary means of storing and retrieving data from the database. |
||||
10 | * An \ElggEntity represents one row of the entities table. |
||||
11 | * |
||||
12 | * The \ElggEntity class handles CRUD operations for the entities table. |
||||
13 | * \ElggEntity should always be extended by another class to handle CRUD |
||||
14 | * operations on the type-specific table. |
||||
15 | * |
||||
16 | * \ElggEntity uses magic methods for get and set, so any property that isn't |
||||
17 | * declared will be assumed to be metadata and written to the database |
||||
18 | * as metadata on the object. All children classes must declare which |
||||
19 | * properties are columns of the type table or they will be assumed |
||||
20 | * to be metadata. See \ElggObject::initializeAttributes() for examples. |
||||
21 | * |
||||
22 | * Core supports 4 types of entities: \ElggObject, \ElggUser, \ElggGroup, and \ElggSite. |
||||
23 | * |
||||
24 | * @tip Plugin authors will want to extend the \ElggObject class, not this class. |
||||
25 | * |
||||
26 | * @package Elgg.Core |
||||
27 | * @subpackage DataModel.Entities |
||||
28 | * |
||||
29 | * @property string $type object, user, group, or site (read-only after save) |
||||
30 | * @property string $subtype Further clarifies the nature of the entity (this should not be read) |
||||
31 | * @property-read int $guid The unique identifier for this entity (read only) |
||||
32 | * @property int $owner_guid The GUID of the owner of this entity (usually the creator) |
||||
33 | * @property int $container_guid The GUID of the entity containing this entity |
||||
34 | * @property int $access_id Specifies the visibility level of this entity |
||||
35 | * @property int $time_created A UNIX timestamp of when the entity was created |
||||
36 | * @property-read int $time_updated A UNIX timestamp of when the entity was last updated (automatically updated on save) |
||||
37 | * @property-read int $last_action A UNIX timestamp of when the entity was last acted upon |
||||
38 | * @property string $enabled Is this entity enabled ('yes' or 'no') |

$md can also be of type integer and false ; however, parameter $var of count() does only seem to accept Countable|array , maybe add an additional type check?
