	/**
	 * This is a method for emulating ON DELETE CASCADE for DBs that don't support this
	 * feature (like MySQL or SQLite).
	 *
	 * This method is not very speedy because it must perform a query first to get
	 * the implicated records and then perform the deletes by calling those Peer classes.
	 *
	 * This method should be used within a transaction if possible.
	 *
	 * @param      Criteria $criteria
	 * @param      PropelPDO $con
	 * @return     int The number of affected rows (if supported by underlying database driver).
