FORCE_DEFAULT_CONSTRUCTORS

#define FORCE_DEFAULT_CONSTRUCTORS

(

CLASS_NAME

)

Value:

    CLASS_NAME(const CLASS_NAME &) = default; \
    CLASS_NAME(CLASS_NAME &) = default; \
    CLASS_NAME(CLASS_NAME &&) = default; \
    \
    CLASS_NAME & operator =(const CLASS_NAME &) = default; \
    CLASS_NAME & operator =(CLASS_NAME &) = default;

Force the default versions of all constructors (copy, move, copy assignment).

MAKE_WRAPPER_CONSTRUCTOR

#define MAKE_WRAPPER_CONSTRUCTOR

(

CLASS_NAME

)

Value:

    FORCE_DEFAULT_CONSTRUCTORS(CLASS_NAME) \
    \
    CLASS_NAME(auto &&... arg) \
        : raw(std::forward<decltype(arg)>(arg)...) \
    { }
