但上述文件未能编译,错误如下:
boost/serialization/access.hpp:116:11: error: 'class boost::container::basic_string<char>' has no member named 'serialize'
boost/serialization/access.hpp:116:11:错误:“class boost::container::basic_string”没有名为“serializate”的成员
同样的代码可以更改为使用std::string
,并且可以很好地编译
是否可以序列化
boost::container::strings
,如果是,我做得不正确或丢失了什么?是。令人惊讶的是,必要的支持并没有融入到Boost中。不过,如果您查看字符串序列化标头内部,您会发现它支持“primitive”,只需一行代码即可启用它:
BOOST_CLASS_IMPLEMENTATION(boost::container::string, boost::serialization::primitive_type)
现在它的工作原理与std::string
相同:
#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/container/string.hpp>
#include <iostream>
BOOST_CLASS_IMPLEMENTATION(boost::container::string, boost::serialization::primitive_type)
struct car {
template<class Ar> void serialize(Ar& ar, unsigned) { ar & make; }
boost::container::string make;
};
int main() {
std::stringstream ss;
{
boost::archive::text_oarchive oa(ss);
car my_car{"ford"};
oa << my_car;
} // close archive
std::cout << ss.str() << "\n";
boost::archive::text_iarchive ia(ss);
car new_car;
ia >> new_car;
}
