BOOST_OPENMETHOD(poke, (virtual_ptr<Animal>), void);
initialize(); // throws missing_class;Missing registration of a class used as a virtual parameter in an overrider:
BOOST_OPENMETHOD_CLASSES(Animal);
BOOST_OPENMETHOD(poke, (virtual_ptr<Animal>), void);
BOOST_OPENMETHOD_OVERRIDE(poke, (virtual_ptr<Dog>), void) { /* ... */ }
initialize(); // throws missing_class;Missing registration of a class used as a virtual parameter in a call:
struct Bulldog : Dog {};
BOOST_OPENMETHOD_CLASSES(Animal, Dog);
BOOST_OPENMETHOD(poke, (virtual_ptr<Animal>), void);
