boost 序列化--C++--serialization--支持常用STL--内存数据文件持久化--继承序列化

2024-01-06 08:55:16

在C++编程中，一个常用的操作是保存数据到文件，用于下次加载时使用，为达到这一目的，boost库提供了序列化的库供使用，源代码如下所示：

#include "boost/serialization/serialization.hpp"
#include "boost/archive/binary_oarchive.hpp"
#include "boost/archive/binary_iarchive.hpp"
#include "boost/foreach.hpp"
#include "boost/any.hpp"
#include "boost/serialization/vector.hpp"
#include "boost/serialization/list.hpp"
#include "boost/serialization/deque.hpp"
#include "boost/serialization/string.hpp"
#include "boost/serialization/split_free.hpp"
#include "boost/serialization/base_object.hpp"
#include "boost/serialization/access.hpp"
#include "boost/serialization/version.hpp"
#include "boost/serialization/export.hpp"
#include "boost/archive/text_iarchive.hpp"
#include "boost/archive/text_oarchive.hpp"

class class1
{
	//序列数据
	friend class boost::serialization::access;
	template<class Archive>//序列化函数
	void serialize(Archive& ar,const unsigned int version)
	{
		ar&m_filename;
		if(Archive::is_loading::value)//加载数据
		{
			ar&m_ANormalLabelSizeMap;
			std::map<std::string,ANormalLabelSize*>::iterator it=m_ANormalLabelSizeMap.begin();
			for (;it!=m_ANormalLabelSizeMap.end();it++)
			{
				//创建对象加载数据
				ANormalLabelSize* pANormalLabelSize=new ANormalLabelSize;
				ar&(pANormalLabelSize);
				it->second = pANormalLabelSize;
			}
		}
		if(Archive::is_saving::value)
		{
			ar&m_ANormalLabelSizeMap;
			std::map<std::string,ANormalLabelSize*>::iterator it=m_ANormalLabelSizeMap.begin();
			for (;it!=m_ANormalLabelSizeMap.end();it++)
			{
				ar&(*(it->second));//保存对象数据
			}
		}
	}
}

父类和子类序列化，源代码如下所示：
