Detailed Description

Abstract function object class.

We use this to avoid having to use function pointers with ugly void pointers to pass type-generic data. Instead, just derive from this interface and add needed data to the derived class.

Example implementation:

class WidgetApplyFunctor : public bwFunctorInterface
{
  bwWidget& some_widget;
 
public:
  WidgetApplyFunctor(bwWidget& widget) :
      some_widget(widget)
  {
  }
 
  inline void operator()() override
  {
    some_widget.do_stuff();
  }
};
