std::shared_ptr and std::unique_ptr serialization support

[JonathasValeriano]

Hi, do you have any plan to support std::shared_ptr and std::unique_ptr in the yas library?

Hi,

Do you mean serialization of polymorphic types?

Hi,
can yas handle runtime polymorphism?

[ambitslix]

Could you elaborate and give an example? I'm guessing you mean serialization via base pointer etc?

[harsh777d]

I want to serialize base pointer that can point to base/derived object. when it get deserialize It should return the proper object.

struct MyClass {
Base* ptr;
MyClass() {
ptr = new Derived(); // or new Base();
}

void serialize(Archive ar) {
ar & ptr;
}
}
when I deserialize, the ptr should point to correct type(Base/Derived).

I think the short answer is no. YAS de/serializes a set of data members that you specify per class. You have to make sure that whatever constructor you end up using after de-serialization will work correctly meaning will get you a proper object instance. As for runtime polymorphism the serialize/deserialize will work like any other function ptr would.
