recvUntimedData

Event* recvUntimedData();

Receive an event during SST's init() or complete() phase. Event handlers are not active during this time, so links must be polled using this function.

Parameters​

  • returns Event received or nullptr if none available

Example​

sst-elements/src/sst/elements/simpleElementExample/basicSimLifeCycle.cc
void basicSimLifeCycle::init(unsigned int phase) {

    // Only send our info on phase 0
    if (phase == 0) {
        basicLifeCycleEvent* event = new basicLifeCycleEvent(getName(), eventsToSend);
        leftLink->sendUntimedData(event);
    }

    // Check if an event is received. recvUntimedData returns nullptr if no event is available
    while (SST::Event* ev = rightLink->recvUntimedData()) {

        basicLifeCycleEvent* event = dynamic_cast<basicLifeCycleEvent*>(ev);

        if (event) {
            if (event->getStr() == getName()) { // Event made it around the ring and back to this component
                delete event;
            } else { // Event is from another component
                neighbors.insert(event->getStr());
                eventsToSend += event->getNum();
                leftLink->sendUntimedData(event);
            }

        } else {
            out->fatal(CALL_INFO, -1, "Error in %s: Received an event during init() but it is not the expected type\n", getName().c_str());
        }
    }
