例如,Boost序列化通过版本控制(BOOST_CLASS_VERSION)和自定义加载函数(load_construct_data)等机制,实现了对不同数据结构版本的支持。 另一方面,Protobuf序列化则侧重于结构的简洁性和前向兼容性。在Protobuf中,通过保持字段编号的一致性和使用可选字段,可以实现不同版本间的无缝数据交换。这种设计减少了版本迁移的复杂...
BOOST_CLASS_VERSION(a,2) 67 BOOST_SERIALIZATION_SHARED_PTR(a) template<class Archive> void save(Archive & ar, const unsigned int version) const 接口完成序列化, template<class Archive> void load(Archive & ar, const unsigned int version) 接口完成反序列化。 BOOST_CLASS_VERSION(a, 2) 指定该...
一种更方便的做法是利用BOOST_CLASS_EXPORT_GUID进行注册,只需要在子类定义处调用下该宏即可。 // 序列化继承类 struct Base { virtual ~Base() = default; string name = "ljw"; double num = 1.5; template <class Archive> inline void serialize(Archive &ar, const unsigned int file_version) { ar ...
