使用模板类提升序列化

【中文标题】使用模板类提升序列化

【英文标题】：Boost serialization with template classes

【问题描述】：

我正在为 linux 中的现有 C++ 项目添加 boost 序列化支持。在该项目中，有一个名为 ContainerT 的模板类，而 MString 是通过使用模板类型作为 char 从该类派生的。

Person类中使用了MString类型，我想对Person类中的数据进行序列化。Person类如下图。（由于实际项目比较大，这里只给出一部分）

#ifndef PERSON_H_
#define PERSON_H_

#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <string>
#include <map>
#include "Container.h"
class Person

public:
    Person();
    Person(std::string _zName,int _iAge);
    ~Person();

private:    
    std::string z_Name;
    int i_Age;
    MString z_CountryCode;


    //Serailization
    //Allow serialization to access non-public data members.
    friend class boost::serialization::access;

    template <typename Archive> 
    void serialize(Archive &ar, const unsigned int version) 
     
        ar & z_Name; 
        ar & i_Age; 
        ar & z_CountryCode; 
       
;


#endif /* PERSON_H_ */

模板类如下。

#ifndef CONTAINER_H_
#define CONTAINER_H_


#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>

template<typename T>
class ContainerT;

template<typename T>
class ContainerDataT

public:
    ContainerDataT();
    ~ContainerDataT();

    T*  GetData()return p_Data;;

private:
    friend class ContainerT<T>;

    T           p_Data[];

    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive &ar, const unsigned int file_version)
    
        ar & p_Data;
    
;

template<typename T>
class ContainerT

public:

    ContainerT();           
    ContainerT(const T* _zData);
    ~ContainerT();
    const T* GetMString() const;

private:

    ContainerDataT<T>*  p_Data;


    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive &ar, const unsigned int file_version)
    
        ar & p_Data;
    
;

template<typename T>
ContainerT<T>::ContainerT()

    p_Data = (ContainerDataT<T>*)malloc(1);
    p_Data->GetData()[0] = 0;



template<typename T>
ContainerT<T>::ContainerT(const T* _zData)

    const T* pChar = _zData;

    while(*pChar != 0)
        ++pChar;
    int iLength = pChar - _zData;

    p_Data = (ContainerDataT<T>*)malloc(500);
    memcpy(p_Data->GetData(), _zData, iLength * sizeof(T));
    p_Data->GetData()[iLength] = 0;


template<typename T>
ContainerT<T>::~ContainerT()

    free(p_Data);


template<typename T>
const T* ContainerT<T>::GetMString() const

    return p_Data->GetData();



typedef ContainerT<char>    MString;

#endif /* CONTAINER_H_ */

当我编译代码时，当我尝试序列化 MString 时出现以下错误。如果我评论了 ar & z_CountryCode;在 Person 类中，每件事都运行良好。有人可以帮助我确定问题所在。有什么特殊的方法可以序列化模板类吗？

【参考方案1】：

这里不仅仅是几个问题。

首先，

ContainerDataT<> 未能遵守三法则 ContainerT<> 未能遵守三法则 在 C++ 中有 malloc/free。只需使用更安全的new/delete（或者更好的是，以异常安全的方式管理所有权语义和生命周期的智能指针）。 T[] 作为成员等同于 T*。

我建议使用标准类型来管理所有权语义（unique_ptr），或者更好的是，只需将标准库用于可变大小动态分配的数组（提示：它是 std::vector）。如果您坚持使用动态分配的数组成员，请诚实对待您的序列化函数：Live On Coliru

template<typename T>
class ContainerDataT : boost::noncopyable 
public:
    ContainerDataT() : p_Data(new T[10])  
    ~ContainerDataT()  delete[] p_Data; 

    T*  GetData()return p_Data;;

private:
    friend class ContainerT<T>;

    T* p_Data;

    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive &ar, const unsigned int file_version) 
        ar & boost::serialization::make_array(p_Data, 10);
    
;

因此，您可以使用boost::serialization::make_array 告诉 Boost Serialization 您的意图。

这是一个简单的演示程序，用于演示（使用分配的固定大小T* p_Data）。请注意，我只是将p_Data 设为ContainerT<> 内的成员对象，因为似乎在进行双重动态实例化方面没有任何好处。
