 /**
  * 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).
