Modelling inter thread communication in activity diagram
I am trying to model an application which runs multiple concurrent flows. In this situation multiple threads can create events and store them in a buffer which are then collected and displayed by another thread. The receiving thread is supposed to block and wait for incoming events.
I have currently modelled it like this:
This example uses object flows. However I am not sure if this is the correct way to model this type of inter thread communication.
The other option I was looking at is using signals but I'm not sure about that either. Any help would be appreciated.
Solution
Every activity requires all tokens to be offered before it can start. You will have to use a buffer node as a queue.
