NAME

       snmpa_notification_filter - Behaviour module for the SNMP agent notification filters.

DESCRIPTION

       This  module  defines  the  behaviour  of  the  agent  notification  filters. A snmpa_notification_filter
       compliant module must export the following functions:

         * handle_notification/2

       The semantics of them and their exact signatures are explained below.

       The purpose of notification filters is to allow for modification and/or suppression of a notification.

       A misbehaving filter will be removed.

EXPORTS

       handle_notification(Notif, Data) -> Reply

              Types:

                 Reply = send | {send, NewNotif} | dont_send
                 Notif = NewNotif = notification() | trap()
                 Data = term()

              Handle a notification to be sent. The filter can either accept  the  notification  as  is,  return
              send,  modify  the  notification,  return  {send,  NewNotif}  or suppress the notification, return
              dont_send.

              Data is supplied at filter registration time, see register_notification_filter.
