snmpa_notification_delivery_info_receiver

MODULE

snmpa_notification_delivery_info_receiver - Behaviour module for the SNMP agent notification delivery information receiver.

DESCRIPTION

This module defines the behaviour of the notification delivery information receiver.

A snmpa_notification_delivery_info_receiver compliant module must export the following functions:

*

delivery_targets/3

*

delivery_info/4

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

DATA TYPES

 address() = A 4-tuple
     
 

EXPORTS

delivery_targets(Tag, Targets, Extra) -> void()

Types

Tag = term()
Targets = [target()]
target() = {Address, Port}
Address = address()
Port = integer()
Extra = term()

Inform about target addresses.
This is the first function called when a notification delivery is in progress. It informs the receiver which targets will get the notification. The result of the delivery will be provided via successive calls to delivery_info/4 function, see below.

delivery_info(Tag, Target, DeliveryResult, Extra) -> void()

Types

Tag = term()
Target = target()
target() = {Address, Port}
Address = address()
Port = integer()
DeliveryResult = delivery_result()
delivery_result() = no_response | got_response
Extra = term()

Inform about delivery result.
This function is called for each target in the Targets argument of the delivery_targets/3 function, see above.
The purpose is to inform the receiver of the result of the delivery (was the notification acknowledged or not) for each target.
