Is there anyway to flush unsent entities from the queue in simevents?

Answer 1

Are you asking if we can clear the queue based on some event? The way I can think to do this to use a MATLAB Discrete Event System block. Actually, there is a good example showing this: Flush Entities from a Queue Server.https://www.mathworks.com/help/simevents/examples/flush-entities-from-a-queue-server.html

That example appears to flush received events, not unsent events?

Answer 2

I'm confused by the question I think. Are you saying that the Entity Generator or Message Send block would lose entities if a queue is full? I'm having a hard time understanding what structure the entities are in (a server?). Are you talking about something like task preemption?
