boost::openmethod::virtual_traits<std::shared_ptr<Class> const&, Registry>

Specialize virtual_traits for std::shared_ptr by reference.

Synopsis

Declared in <boost/openmethod/interop/std_shared_ptr.hpp>

template<
    class Class,
    class Registry>
struct virtual_traits<std::shared_ptr<Class> const&, Registry>;

Description

Passing a std::shared_ptr in a method call by const reference creates a temporary std::shared_ptr and passes it by const reference to the overrider. This is necessary because virtual arguments need to be cast to the type expected by the overrider.
