first of all, Cint is GREAT for testing hardware. It's so useful to be
able to call memberfunctions interactively and watch what happens at the
outputs.
-------------------------------------------------------
I have a problem with virtual base classes:
Everything works fine, when MAdc and MTrigger are derived from
MDaq WITHOUT virtual,
//****************************
class MDaq : public TObject
{ ........ClassDef(MDaq,0) }
class MAdc : public virtual MDaq
{ ........ClassDef(MAdc,0) }
class MTrigger : public virtual MDaq
{ ........ClassDef(MTrigger,0) }
//******************************
but as is, I get the compiler error:
MAdc_Cint.cxx: In function `class TBuffer & operator >>(class TBuffer &, class MAdc *&)':
MAdc_Cint.cxx:424: cannot cast up from virtual baseclass `MDaq'
Is the problem that there is only ONE TObject for several
derived classes? But to derive MAdc directly from TObject
additionally doesn't work either.
thanks,
