67 * DB_DataObject needs to know something about the table to manipulate
68 * instances. This method provides all the DB_DataObject needs to know.

81 * return key definitions for DB_DataObject
83 * DB_DataObject needs to know about keys that the table has, since it
84 * won't appear in StatusNet's own keys list. In most cases, this will
85 * simply reference your keyTypes() function.
87 * @return array list of key field names
91 return array_keys($this->keyTypes());
95 * return key definitions for Memcached_DataObject
97 * Our caching system uses the same key definitions, but uses a different
98 * method to get them. This key information is used to store and clear
99 * cached data, so be sure to list any key that will be used for static
102 * @return array associative array of key definitions, field name to type:
103 * 'K' for primary key: for compound keys, add an entry for each component;
104 * 'U' for unique keys: compound keys are not well supported here.

112 * Magic formula for non-autoincrementing integer primary keys
114 * If a table has a single integer column as its primary key, DB_DataObject
115 * assumes that the column is auto-incrementing and makes a sequence table
116 * to do this incrementation. Since we don't need this for our class, we
117 * overload this method and return the magic formula that DB_DataObject needs.
119 * @return array magic three-false array that stops auto-incrementing.
