静态成员和系列化提振 [英] static members and boost serialization

问题描述

我使用加速。序列化，以便存档类的内容。其中一个成员变量是一个静态的std ::向量。

I'm using Boost.Serialization to archive the contents of a class. One of the member variables is a static std::vector.

归档和恢复去罚款，但我是那种希望图书馆将节省静态成员只有一次，看来，在文件大小来看，静态成员完全保存每个存档实例。

Archiving and restoring goes fine, but I was kind of hoping the library would save static members only once, it appears that, judging by the filesize, the static members are fully saved for each archived instance.

这是比较容易通过设置/吸气的静态矢量和序列化类的外部静态矢量一次规避。

This is rather easily circumvented by using set/getters for the static vector and serializing the static vector outside the class once.

不过，我宁愿有一个自包含的类。是否有一个清洁，简单的方法来实现归档一类的静态内容只有一次？

But I'd rather have a self contained class. Is there a clean and easy way to achieve archiving the static contents of a class only once?

推荐答案

序列化静态载体序列化的所有类的实例。之前

Serialize the static vector before you serialize all of the class' instances.

如果您序列化向量是这样的：

If you serialize the vector like this:

template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{
    ar & this->someVar;
    ar & this->AnotherVar;
    ar & staticVector;  
}

然后肯定的是，静态矢量不会获取序列化每个实例。

Then sure, the static vector does get serialized with each instance.

如果您需要任何进一步澄清，发表您的连载函数调用它的功能，请。

Should you need any further clarification, post your serialize function and the function that invokes it, please.
