[Omnetpp-l] SingleChannelRadio.cc of mfo4 question

[giorgio corbellini <gcorbellini at xxx>]

Hi, 
at the line 158 of the file contrib/nic/radios/SingleChannelRadio.cc (full text here)

there is the call of this method:

bool SingleChannelRadio::switchTo(RadioState::States s, simtime_t delta) 

{
    bool success = true;

 
    EV << "current state:" << state.getState() << ", last state:" << RadioState::SWITCH_TO_SLEEP

       << " handlingTimer:" << handlingTimer << endl;

    if((state.getState() < RadioState::SWITCH_TO_SLEEP) && (handlingTimer == false))

    {
        state.setState(s);

        scheduleAt(simTime() + delta, timer);

        bb->publishBBItem(stateCat, &state, nicModuleId);

    } else {
  EV << "error, radio couldn't be switched!\n";

        success = false;
    }


    return success;
}

I don't understand why the if condition is always depending on  

"RadioState::SWITCH_TO_SLEEP"

and not on the method input "s", can anybody explain me?




thanks

Giorgio
