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_notifica-
       tion_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.

	      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 .
