67 * return table definition for DB_DataObject
69 * DB_DataObject needs to know something about the table to manipulate
70 * instances. This method provides all the DB_DataObject needs to know.
72 * @return array array of column definitions
77 return array('id' => DB_DATAOBJECT_INT + DB_DATAOBJECT_NOTNULL,
78 'state' => DB_DATAOBJECT_STR,

84 'messages_newest' => DB_DATAOBJECT_INT,
85 'created' => DB_DATAOBJECT_STR + DB_DATAOBJECT_DATE + DB_DATAOBJECT_TIME + DB_DATAOBJECT_NOTNULL);
89 * return key definitions for DB_DataObject
91 * DB_DataObject needs to know about keys that the table has, since it
92 * won't appear in StatusNet's own keys list. In most cases, this will
93 * simply reference your keyTypes() function.
95 * @return array list of key field names
100 return array_keys($this->keyTypes());
104 * return key definitions for Memcached_DataObject
106 * Our caching system uses the same key definitions, but uses a different
107 * method to get them. This key information is used to store and clear
108 * cached data, so be sure to list any key that will be used for static
111 * @return array associative array of key definitions, field name to type:
112 * 'K' for primary key: for compound keys, add an entry for each component;
113 * 'U' for unique keys: compound keys are not well supported here.
118 return array('id' => 'K');
122 * Magic formula for non-autoincrementing integer primary keys
124 * If a table has a single integer column as its primary key, DB_DataObject
125 * assumes that the column is auto-incrementing and makes a sequence table
126 * to do this incrementation. Since we don't need this for our class, we
127 * overload this method and return the magic formula that DB_DataObject needs.
129 * @return array magic three-false array that stops auto-incrementing.
