7 C++ Boost 序列化
1,关于序列化.png 2,关于序列化.png 3,关于序列化.png 将结构体写入文件 name存在空格,C++的序列化相当的脆弱 C++ 序列化 二进制版 C风格的 序列化,总是正常的 boost 序列化C风格 写入到文件simple boost 序列化C++风格 写入到文件simple boost 序列化从文件中读取 非侵入式的 boost序列化 缺点:所有的成员必须是public 可序列化的成员 派生类的序列化,问题引出,父类的成员增删对序列化有影响.耦合度太高 派生类的序列化 问题解决 指针的序列化 两个指针指向同一片区域,序列化到文件,只保存一份 智能指针的序列化 数组的序列化 指针数组的序列化 STL容器的序列化 将对象序列化为XML描述
