Boost c ++序列化char * [英] Boost c++ serializing a char *

问题描述

我有一个类，我试图序列化一个shared_ptr，但序列化对象的正常方法不工作：

I have a class and I am trying to serialize a shared_ptr but the normal method of serializing an object is not working:

class Object {
public:
    Object();
    ~Object();

    shared_ptr<char>objectone;

    friend class boost::serialization::access;
    template <typename Archive>
    void serialize(Archive &ar, const unsigned int version)
    {
        ar & objectone;
    }
};

我已经尝试过这种方式，但它仍然不工作：

I've even attempted it in this way but it still doesn't work:

    void serialize(Archive &ar, const unsigned int version)
    {
        for (int i = 0; i < (strlen(objectone.get())); i++)
             ar & objectone.get()[i];
    }

任何想法如何处理？非常感谢。

Any ideas how to approach this? Thanks.

一些额外的信息：

我已经包括了两个shared_ptr头文件：

I've already included both shared_ptr header files:

#include <boost/serialization/shared_ptr.hpp>
#include <boost/serialization/shared_ptr_132.hpp>

我试图转换为字符串并以这种方式序列化，但它会产生以下错误：
boost :: archive :: archive_exception'
what（）：stream error

I've attempted to convert to a string and serialize it in that way but it produces the following error: boost::archive::archive_exception' what(): stream error

friend class boost::serialization::access;
template <typename Archive>
void serialize(Archive &ar, const unsigned int version)
{
    if (objectone.get()) {
        string temp(objectone.get());
        ar & temp;
    }
    ar & objectone;
}

推荐答案

。

您可以执行

class Object {
public:
    Object();
    ~Object();

    std::string name;

    template <typename Archive>
    void serialize(Archive &ar, const unsigned int version)
    {
        ar & name;
    }
};

完成。

根据您的要求，这是您必须做的

Given your requirements this is what you have to do

class test
{
public:

friend class boost::serialization::access;

test() 
{       
}

template<class Archive>
void save(Archive & ar, const unsigned int version) const
{
    int len = strlen(data.get());
    ar  & len;
    for (int index = 0; index < len; ++index)
        ar & data[index];       
}
template<class Archive>
void load(Archive & ar, const unsigned int version)
{
    int len = 0;
    ar  & len;
    data = boost::shared_array<char>(new char[len+1]);
    for (int index = 0; index < len; ++index)
        ar & data[index];
    data[len] = 0;
}
BOOST_SERIALIZATION_SPLIT_MEMBER()

boost::shared_array<char> data;
};
