-/**
- * Implements TActiveRecord::HAS_MANY relationship between the source object having zero or
- * more foreign objects. Consider the <b>entity</b> relationship between a Team and a Player.
- * <code>
- * +------+ +--------+
- * | Team | 1 <----- * | Player |
- * +------+ +--------+
- * </code>
- * Where one team may have 0 or more players and each player belongs to only
- * one team. We may model Team-Player <b>object</b> relationship as active record as follows.
- * <code>
- * class TeamRecord extends TActiveRecord
- * {
- * const TABLE='team';
- * public $name; //primary key
- * public $location;
- *
- * public $players=array(); //list of players
- *
- * public static $RELATIONS=array
- * (
- * 'players' => array(self::HAS_MANY, 'PlayerRecord')
- * );
- *
- * public static function finder($className=__CLASS__)
- * {
- * return parent::finder($className);
- * }
- * }
- * class PlayerRecord extends TActiveRecord
- * {
- * // see TActiveRecordBelongsTo for detailed definition
- * }
- * </code>
- * The static <tt>$RELATIONS</tt> property of TeamRecord defines that the
- * property <tt>$players</tt> has many <tt>PlayerRecord</tt>s.
- *
- * The players list may be fetched as follows.
- * <code>
- * $team = TeamRecord::finder()->with_players()->findAll();
- * </code>
- * The method <tt>with_xxx()</tt> (where <tt>xxx</tt> is the relationship property
- * name, in this case, <tt>players</tt>) fetchs the corresponding PlayerRecords using
- * a second query (not by using a join). The <tt>with_xxx()</tt> accepts the same
- * arguments as other finder methods of TActiveRecord, e.g. <tt>with_players('age < ?', 35)</tt>.
