  /**
   * <pre>
   *   Base class for ignorable log events. Events deriving from
   *   this class can be safely ignored by slaves that cannot
   *   recognize them. Newer slaves, will be able to read and
   *   handle them. This has been designed to be an open-ended
   *   architecture, so adding new derived events shall not harm
   *   the old slaves that support ignorable log event mechanism
   *   (they will just ignore unrecognized ignorable events).
   * 
   *   @note The only thing that makes an event ignorable is that it has
   *   the LOG_EVENT_IGNORABLE_F flag set.  It is not strictly necessary
   *   that ignorable event types derive from Ignorable_log_event; they may
   *   just as well derive from Log_event and pass LOG_EVENT_IGNORABLE_F as
   *   argument to the Log_event constructor.
   * </pre>
