如何序列化boost :: uuids :: uuid
我目前在项目中使用boost :: uuids :: uuid，我想序列化包含boost :: uuids :: uuid的对象。 我尝试了下面的简单示例，但出现错误：
/usr/include/boost/archive/basic_text_oprimitive.hpp:92：错误：'（（boost :: archive :: basic_text_oprimitive> *）this'中的'operator <<'不匹配） - > boost :: archive :: basic_text_oprimitive > :: os << t'
如果有人能够帮助我，我会真正感到满意。
#include <fstream>
#include <boost/uuid/uuid.hpp>
#include <boost/uuid/uuid_generators.hpp>
#include <boost/uuid/uuid_serialize.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
class classA {
public:
classA() : id(boost::uuids::random_generator()()) {}
private:
friend class boost::serialization::access;
boost::uuids::uuid id;
template <class Archive>
void serialize(Archive& ar, const unsigned int version) {
ar & id;
}
};
int main(void) {
classA a;
std::ofstream ofs("uuid.txt");
boost::archive::text_oarchive oa(ofs);
oa << a;
ofs.close();
return 0;
}
包含<boost/uuid/uuid_serialize.hpp>以启用uuids的序列化。 http://www.boost.org/doc/libs/1_42_0/libs/uuid/uuid.html#boost/uuid/uuid_serialize.hpp
