operator==()

virtual bool DD::Image::Knob::VisibilityCallbackFunctor::operator== ( const VisibilityCallbackFunctor &  cs ) const

pure virtual

operator== is required to identify callbacks. This is guaranteed only to be called with the same type so use: const MyFunctor& myFunctor = static_cast<const MyFunctor&>(cb);
