Multiple inheritance for reactive interfaces in C

See this idea on ideas.ibm.com

Hello IBM team,


When using Rhapsody in C, it is possible to add inheritance from interfaces within classes. As long as these interfaces are not reactive interfaces, meaning they do not contain event receptions, multiple inheritances from different interfaces can be defined within a class, and code can be generated accordingly.

However, if a class inherits from more than one reactive interface, the model checker reports an error, stating that this is not supported in Rhapsody in C.

This behavior may be correct for Rhapsody in C when the underlying OXF framework is used. However, when using the RXF framework provided with Rhapsody, it is indeed possible to inherit from multiple reactive interfaces. Unfortunately, this specific model checker is a fixed component of Rhapsody and cannot be disabled for code generation (Even when it is disabled in the configuration).

As developers of the RXF, we have received multiple inquiries from customers across the railway, automotive, and defense industries regarding this issue. Removing this restriction would provide significant value.

It would be very helpful, if the model checker for multiple inheritance of reactive interfaces could also be disabled when triggering the code generation.

Thank you,
Michael
