如何使用boost系列化

Question

我試圖序列具有類成員變量一樣的std :: list類> LSS

#include <boost/serialization/optional.hpp> 
#include <boost/serialization/map.hpp> 
#include <boost/serialization/shared_ptr.hpp> 
#include <boost/serialization/serialization.hpp> 
#include <boost/serialization/list.hpp> 

struct SomeStruct 
{ 
    int x; 
    double y; 

    private: 
     friend class boost::serialization::access; 
     template<class Archive> 
     void serialize(Archive &at, const unsigned int version) 
     { 
     at & x; 
     at & y; 
     } 

}; 

class BuildTest 
{ 

    std::list<boost::shared_ptr<SomeStruct *>> lss ; 
    std::string name; 

    private: 
     friend class boost::serialization::access; 
     template<class Archive> 
     void serialize(Archive &at, const unsigned int version) 
     { 
     at & lss; // is this sufficient to serialize lss ? 
     at & name; 
     } 

} 

我已經添加了所有需要的頭序列化類型的shared_ptr指針類型的列表升壓序列化文件。有類似的問題，但通過適當的答案how do i serialize list variable of type <boost::shared_ptr<void *>>

Answer 1

你想

std::list<boost::shared_ptr<SomeStruct>> lss ; 

不std::list<boost::shared_ptr<SomeStruct*>>

struct SomeStruct { 
    int x; 
    double y; 

private:

}; 

int main() { 
    BuildTest bt; 
    bt.name = "Let's try this"; 
    bt.lss = { boost::make_shared<SomeStruct>(), boost::make_shared<SomeStruct>() }; 
    boost::archive::text_oarchive oa(std::cout); 
    oa << bt; 
}
