Question & Answer
Question
How do you relay an event generated by MULTICAS_GEN macro to more than one port located inside an composite class?
Cause
This is a known limitation.
Multicasting through regular ports are supported only in direct 1 hop.
In case of the image at right, multicasted events originated from portA can only be received by 1 port (either portC or portD).
Answer
WORKAROUND:
You can implement a delegator class that forwards any incoming events to inner ports. See the image below.
For details, refer the attached model built using v8.1. In this model, please notice below points.
- Property '<Lang>::Port::SupportMulticast' of 'portE2' is set to 'Always'.
- In statechart of delegator class (itsE), MULTICAST_GEN (for C++) and RiC_MULTICAST_GEN_PORT (for C) macro is used to multicast events, instead of having them called from itsA.
