bool GpCoreTools::Timer::after

(

Timer *

o

)

const

References TRACE.

{
  TRACE;
  if(_timeout.tv_sec>o->_timeout.tv_sec) {
    return true;
  } else if(_timeout.tv_sec<o->_timeout.tv_sec) {
    return false;

GpCoreTools::Timer::exec

(

)

[pure virtual]

Performs action after timeout. If it returns true the timer is not single shot, i.e. deleted right after exec().

Implemented in GpCoreTools::ScreenClientConnect, NavigationTimer, IpRouteWatch, LinkMeasureTimer, LinkTestTimer, TimeRequest, BeaconTimer, DeadPeersTimer, and LinkTimer.

const [inline]

Referenced by DeadPeersTimer::exec().

{return _interval;}

bool GpCoreTools::Timer::isRunning

(

)

[inline]

{return _queued;}

void GpCoreTools::Timer::printDebug

(

)

References timeout(), and TRACE.

{

  printf("Timer interval=%i, abs_timeout_sec=%li, abs_timeout_nsec=%li, rel_timeout=%i, running=%s\n",
         _interval, _timeout.tv_sec, _timeout.tv_nsec, timeout(), _queued ? "yes" : "no");
}

GpCoreTools::Timer::setInterval

(

int

i

)

[inline]

Sets delay to i ms.
