35 * Temporary storage for imported Yammer messages between fetching and saving
38 * The Yammer API only allows us to page down from the most recent items; in
39 * order to start saving the oldest notices first, we have to pull them all
40 * down in reverse chronological order, then go back over them from oldest to
41 * newest and actually save them into our notice table.

53 * This is a utility method to get a single instance with a given key value.

79 * return table definition for DB_DataObject
81 * DB_DataObject needs to know something about the table to manipulate
82 * instances. This method provides all the DB_DataObject needs to know.
84 * @return array array of column definitions
88 return array('id' => DB_DATAOBJECT_INT + DB_DATAOBJECT_NOTNULL,
89 'json_data' => DB_DATAOBJECT_STR + DB_DATAOBJECT_NOTNULL,
90 'created' => DB_DATAOBJECT_STR + DB_DATAOBJECT_DATE + DB_DATAOBJECT_TIME + DB_DATAOBJECT_NOTNULL);
94 * return key definitions for DB_DataObject
96 * DB_DataObject needs to know about keys that the table has, since it
97 * won't appear in StatusNet's own keys list. In most cases, this will
98 * simply reference your keyTypes() function.
100 * @return array list of key field names
105 return array_keys($this->keyTypes());
109 * return key definitions for Memcached_DataObject
111 * Our caching system uses the same key definitions, but uses a different
112 * method to get them. This key information is used to store and clear
113 * cached data, so be sure to list any key that will be used for static
116 * @return array associative array of key definitions, field name to type:
117 * 'K' for primary key: for compound keys, add an entry for each component;
118 * 'U' for unique keys: compound keys are not well supported here.
122 return array('id' => 'K');
126 * Magic formula for non-autoincrementing integer primary keys
128 * If a table has a single integer column as its primary key, DB_DataObject
129 * assumes that the column is auto-incrementing and makes a sequence table
130 * to do this incrementation. Since we don't need this for our class, we
131 * overload this method and return the magic formula that DB_DataObject needs.
133 * @return array magic three-false array that stops auto-incrementing.

151 * Save the native Yammer API representation of a message for the pending
152 * import. Since they come in in reverse chronological order, we need to
153 * record them all as stubs and then go through from the beginning and
154 * save them as native notices, or we'll lose ordering and threading
157 * @param integer $orig_id ID of the notice on Yammer
158 * @param array $data the message record fetched out of Yammer API returnd data
