假如有一个基类如下：
class student_info
{
public:
student_info() {}
virtual ~student_info() {}
student_info(const std::string& sn, const std::string& snm, const std::string& sg)
: name_(sn), number_(snm), grade_(sg)
{
}
virtual void print_info() const
{
std::cout << name_ << " " << number_ << " " << grade_ << std::endl;
}
private:
std::string name_;
std::string number_;
std::string grade_;
};它的一个派生类如下：
class middle_student : public student_info
{
public:
middle_student() {}
virtual ~middle_student() {}
middle_student(const std::string& sn, const std::string& snm, const std::string& sg, int age)
: student_info(sn, snm, sg), age_(age)
{
}
virtual void print_info()
{
student_info::print_info();
std::cout << age_ << std::endl;
}
private:
int age_;
};我们如何在序列化派生类的同时序列化基类？private:
friend class boost::serialization::access;
template<typename Archive>
void serialize(Archive& ar, const unsigned int version)
{
ar & boost::serialization::base_object<student_info>(*this);//使用基类的序列化
ar & BOOST_SERIALIZATION_NVP(age_);
}记住需要包含头文件 <boost/serialization/base_object.hpp>，这样就解决问题了class student_info
{
public:
student_info() {}
virtual ~student_info() {}
student_info(const std::string& sn, const std::string& snm, const std::string& sg)
: name_(sn), number_(snm), grade_(sg)
{
}
virtual void print_info() const
{
std::cout << name_ << " " << number_ << " " << grade_ << std::endl;
}
private:
friend class boost::serialization::access;
template<typename Archive>
void serialize(Archive& ar, const unsigned int version)
{
ar & BOOST_SERIALIZATION_NVP(name_);
ar & BOOST_SERIALIZATION_NVP(number_);
ar & BOOST_SERIALIZATION_NVP(grade_);
}
private:
std::string name_;
std::string number_;
std::string grade_;
};
class middle_student : public student_info
{
public:
middle_student() {}
virtual ~middle_student() {}
middle_student(const std::string& sn, const std::string& snm, const std::string& sg, int age)
: student_info(sn, snm, sg), age_(age)
{
}
virtual void print_info()
{
student_info::print_info();
std::cout << age_ << std::endl;
}
private:
friend class boost::serialization::access;
template<typename Archive>
void serialize(Archive& ar, const unsigned int version)
{
ar & boost::serialization::base_object<student_info>(*this);
ar & BOOST_SERIALIZATION_NVP(age_);
}
private:
int age_;
};
