%%====================================================================
%%--------------------------------------------------------------------
%% Function: init(Args) -> {ok, State}
%% Description: Whenever a new event handler is added to an event manager,
%% this function is called to initialize the event handler.
%%--------------------------------------------------------------------
init(_) ->
{ok,#state{}}.
%%--------------------------------------------------------------------
%% Function:
%% handle_event(Event, State) -> {ok, State} |
%% {swap_handler, Args1, State1, Mod2, Args2} |
%% remove_handler
%% Description:Whenever an event manager receives an event sent using
%% gen_event:notify/2 or gen_event:sync_notify/2, this function is called for
%% each installed event handler to handle the event.
%%--------------------------------------------------------------------
%%============================== EVENTS ==============================
%%
%% Events documented in ct_event, plus:
%%
%% Name = pending_make
%% Data = {Node,Dir}
%%
%% Name = go_ahead_make
%% Data = {Node,Dir}
%%
handle_event(#event{name=Name,node=Node,data=Data},State) ->
print("~n=== ~w ===~n", [?MODULE]),
print("~p on ~p: ~p~n", [Name,Node,Data]),
{ok,State}.
%%--------------------------------------------------------------------
%% Function:
%% handle_call(Request, State) -> {ok, Reply, State} |
%% {swap_handler, Reply, Args1, State1,
%% Mod2, Args2} |
%% {remove_handler, Reply}
%% Description: Whenever an event manager receives a request sent using
%% gen_event:call/3,4, this function is called for the specified event
%% handler to handle the request.
%%--------------------------------------------------------------------
handle_call(_Req, State) ->
Reply = ok,
{ok, Reply, State}.
%%--------------------------------------------------------------------
%% Function:
%% handle_info(Info, State) -> {ok, State} |
%% {swap_handler, Args1, State1, Mod2, Args2} |
%% remove_handler
%% Description: This function is called for each installed event handler when
%% an event manager receives any other message than an event or a synchronous
%% request (or a system message).
%%--------------------------------------------------------------------
handle_info(_Info, State) ->
{ok, State}.
%%--------------------------------------------------------------------
%% Function: terminate(Reason, State) -> void()
%% Description:Whenever an event handler is deleted from an event manager,
%% this function is called. It should be the opposite of Module:init/1 and
%% do any necessary cleaning up.
%%--------------------------------------------------------------------
terminate(_Reason, _State) ->
ok.
%%--------------------------------------------------------------------
%% Function: code_change(OldVsn, State, Extra) -> {ok, NewState}
%% Description: Convert process state when code is changed
%%--------------------------------------------------------------------
code_change(_OldVsn, State, _Extra) ->
{ok, State}.
%%--------------------------------------------------------------------
%%% Internal functions
%%--------------------------------------------------------------------
print(_Str,_Args) ->
ok.
