示例1: takeEvents

bool EventQueue::takeEvents(Events& events, double cutOffTime)
{
    OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_eventQueueMutex);
    if (!_eventQueue.empty())
    {
        // find last event if queue that came in before the cuttof.
        Events::reverse_iterator ritr = _eventQueue.rbegin();
        for(; ritr != _eventQueue.rend() && ((*ritr)->getTime() > cutOffTime); ++ritr) {}

        if (ritr==_eventQueue.rend()) return false;

        for(Events::iterator itr = _eventQueue.begin();
            itr != ritr.base();
            ++itr)
        {
            events.push_back(*itr);
        }

        // make sure that the events are in ascending time order, and any out of out events
        // have their time reset to the next valid time after them in the events list.
        double previousTime = cutOffTime;
        for(Events::reverse_iterator itr = events.rbegin();
            itr != events.rend();
            ++itr)
        {
            if ((*itr)->getTime() > previousTime)
            {
                OSG_INFO<<"Reset event time from "<<(*itr)->getTime()<<" to "<<previousTime<<std::endl;
                (*itr)->setTime(previousTime);
