U BPA STATIC ROFLECTION
Только для заголовка, крошечная (99 линий) и мощная библиотека статического отражения C ++ 20.
Запустите его онлайн: компилятор Explorer
Предположим, вам нужно отразить struct Vec
struct Vec {
float x;
float y;
float norm () const { return std::sqrt (x*x + y*y); }
}; template <>
struct Ubpa ::USRefl::TypeInfo<Vec> :
TypeInfoBase<Vec>
{
static constexpr AttrList attrs = {};
static constexpr FieldList fields = {
Field { TSTR ( " x " ) , &Type::x },
Field { TSTR ( " y " ) , &Type::y },
Field { TSTR ( " norm " ), &Type::norm},
};
};Если вы используете версию на 99 линий, вам нужно добавить линию
static constexpr std::string_view name = " ... " ;
TypeInfo<Vec>::fields.ForEach([]( const auto & field) {
std::cout << field. name << std::endl;
}); std::invoke (TypeInfo<Vec>::fields.Find(TSTR( " y " )).value, v) = 4.f;
std::invoke (TypeInfo<Vec>::fields.Find(TSTR( " x " )).value, v) = 3.f;
std::cout
<< " x: "
<< std::invoke(TypeInfo<Vec>::fields.Find(TSTR( " x " )).value, v)
<< std::endl;std::cout
<< " norm: "
<< std::invoke(TypeInfo<Vec>::fields.Find(TSTR( " norm " )).value, v)
<< std::endl;TypeInfo<Vec>::ForEachVarOf(v, []( const auto & field, const auto & var) {
std::cout << field. name << " : " << var << std::endl;
