序列化C ++对象 [英] Serializing C++ objects

问题描述

我想实现一个序列化类，它接收一个对象，并将其转换为二进制流并存储在文件中。后来，应该从一个文件重建对象。

I would like to implement a Serialization Class which takes in an object and converts it into a binary stream and stored in a file. Later, the object should be reconstructed from a file.

虽然这个功能是由BinaryFormatter在C＃提供的，我想设计我的
自己的序列化类

Though this functionality is provided by BinaryFormatter in C#, I would like to design my own Serialization class from scratch.

有人可以指向某些资源吗？

Can someone point to some resources ?

提前感谢

推荐答案

我一直使用boost :: serialization库一段时间，我认为这是非常好的。你只需要创建这样的序列化代码：

I have been using boost::serialization library for a while now and I think it is very good. You just need to create the serialization code like this:

class X {
  private:
    std::string value_;
  public:
    template void serialize(Archive &ar, const unsigned int version) {
       ar & value_;
     };
 }

无需创建反序列化代码（这就是为什么他们使用& amp ;运算符）。但如果你喜欢你仍然可以使用<<和>>运算符。

No need to create the de-serialization code ( that's why they used the & operator ). But if you prefer you can still use the << and >> operators.

也可以为没有修改的类编写序列化方法（例如：如果需要序列化来自库的对象）。在这种情况下，您应该做类似的操作：

Also it's possible to write the serialization method for a class with no modification ( ex.: if you need to serialize an object that comes from a library ). In this case, you should do something like:

namespace boost { namespace serialization {
       template
       void serialize(Archive &ar, X &x const unsigned int version) {
                    ar & x.getValue();
       };
    }}
