setFunctor

void setFunctor(Event::HandlerBase* functor);

Set the callback handler for events arriving on a link. Does not delete the previous handler that was registered to the Link.

note

This function cannot be used on a Link that was configured as a polling link (i.e., configured without a handler).

Parameters​

  • functor (Event::HandlerBase*) Event handler to invoke for event arrivals
  • returns none

Example​

// Configure a link connected to a port named 'port' 
Event::HandlerBase* handler = new Event::Handler<example>(this, &example::handleEvent);
SST::Link* link = configureLink("port", handler);

// Change the link to call otherHandleEvent() instead of handleEvent() when an event arrives
// setFunctor won't delete the existing handler so we can reuse it later if we want to swap again
link->setFunctor(new Event::Handler<example>(this, &example::otherHandleEvent));
