Bug 48

Summary:	Create function and parameters that are from virtual classes

Description Emmanuelle Laprise 2007-07-13 11:52:32 EDT

Is it normal that the Create function works only if ontime and offtime are not from a class that has virtual functions? That is, if I define them as ConstantVariable, then it compiles, but if I define than as RandomVariable (virtual base class) and pass in a ConstantVariable (derived class), then it won't compile telling me that the RandomVariable class has some pure virtual functions.

FunctionXX(const  RandomVariable& ontime, const  RandomVariable& offtime)
{
  m_onOffGenerator = Create<OnOffGenerator> (ontime, offtime);
}

Thanks,

Emmanuelle

Could you provide a reduced test case without OnOffGenerator ?

mark as INVALID?  (no test case provided)

Comment 3 Mathieu Lacage 2008-06-05 12:44:18 EDT

ok.
