-module(snmpa_get_mechanism).
%%
%% This module defines the behaviour for the undocumented (hidden)
%% get-mechanism feature. This allows for implementing your own
%% handling of get, get-next and get-bulk requests.
%% Probably only useful for special cases (e.g. optimization).
%%
%% ----------- do_get/2,3 -----------------------------------------------------
%% Purpose: Handles all VBs in a request that is inside the
%% mibview (local).
-callback do_get(UnsortedVBs :: [snmp:varbind()],
IsNotification :: boolean(),
Extra :: term()) ->
{noError, 0, ResVBs :: [snmp:varbind()]} |
{ErrStatus :: snmp:error_status(), ErrIndex :: snmp:error_index(), []}.
%% Purpose: Handles "get-requests".
