Erlang OTP: Megaco digit map handler

2009-08-17T21:57:00.000-07:00

Erlang OTP Megaco (H.248) stack has digit map handler which starts up with given digit map, receives dialing events then returns result of dialing. To better working with digitmap let's wrote wrapper:


start(Pid) ->
    start_dm_proc(Pid, "(8|0x|[0-79]xxxxx|8xxxxxxxxxx|[0-9]x|E|F|x.F|[0-9].L)", 0, 2, 3, 100).

start_dm_proc(Pid, DM, St, Sh, Ln, Dr) ->
    DMV = #'DigitMapValue'{startTimer = St, shortTimer = Sh, longTimer = Ln, digitMapBody = DM, durationTimer = Dr},
    spawn(?MODULE, tde_proc, [Pid, DMV]).

tde_proc(Pid, DMV) ->
    Res = megaco:eval_digit_map(DMV),
    gen_fsm:send_event(Pid, {dial_result, Res}).

Spawned tde_proc/2 (with parent process ID and digit map) can receive digit-events with function megaco:report_digit_event/2 call with eval process ID and dialed digit symbol:


megaco:report_digit_event(EvalPid, Evt)

When reported digits matches with digit map, megaco:eval_digit_map/1 returns such result as: {ok, {full, Number}} or {ok, {unambiguous, Number}} if '#' pressed (dial event 'F').

gen_fsm:send_event(Pid, {dial_result, Res}) sends this result to parent process.

Dialyzer warning: no local return

2009-05-29T22:24:00.000-07:00

When you have analyzing erlang beams with a dialyzer and see that warning:


module.erl:51: Function init/1 has no local return

check out all used records in this function for right type definitions of its items. For example, if record defined as


-record(state, {
      name :: string(),
      data :: binary()
 }

and usage of state is


init([]) ->
  {ok, #state{name = "Name", data = "Data"}}

this warning will appears.

make_ref() hint

2009-05-20T22:23:00.000-07:00

BIF make_ref() returns built-in type ref() which is unique on this node. Type ref() contains name of node if erl started with -sname or -name parameters, therefore we can use ref() in distributed systems for some unique value through all nodes. BTW, keep in mind that reference will re-occur after approximately 2^82 calls.
