OMNeT++/Veins problem using cSimpleModule

Question

I'm implementing vanet with OMNeT++ 5.3 and Veins 4.7.1 but I'm experiencing errors that I can't solve.

The code:

public:
    SienaStatisticsAccess() { }
    SienaStatistics* getIfExists() {
        //Finds a module by its path.
        return dynamic_cast<SienaStatistics*>(simulation.getModuleByPath("stats"));
    }

The error:

'simulation’ was not declared in this scope

Answer 1

The code should look like:

return dynamic_cast<SienaStatistics*>(getSimulation()->getModuleByPath("stats"));

Using this at least the 'simulation’ was not declared in this scope will be gone.
