自己写的代码片段1

namespace g{ //数据交换 template<class T> void Swap(T &t1, T &t2){ T temp = t1;t1 = t2; t2 = temp;}//数据夹值 template<class T>void Clamp(T &value, const T &min, const T &max){ if(value < min){ value = min; return;} if(value > max){ value = max; return;} } } 自己写的代码片段1

很简单的:)

 #ifndef G_MATH_HPP#define G_MATH_HPPnamespace g{ //数据交换 template<class T> void Swap(T &t1, T &t2); //数据夹值 template<class T> void Clamp(T &value, const T &min, const T &max); };//包含内联函数文件#include "Math.inl"#endif

 

  //ar & boost::serialization::base_object<bus_stop>(*this);#ifndef G_POINT_HPP#define G_POINT_HPP#ifdef G_USE_BOOST_ARCHIVE #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #define ACCESS_ARCHIVE #define USE_ARCHIVE#else #define ACCESS_ARCHIVE #endif #include "Math.hpp" namespace g{//使用序列化template<class T>struct Point{Point(); Point(const T &x, const T &y);Point(const Point<T> &point);Point<T>& operator = (const Point<T> point);void Swap(Point<T> &point);void Set(const T &x, const T &y);void Clear(); bool operator ==(const Point<T> point); Point<T>& operator -(const Point<T> point); Point<T>& operator +(const Point<T> point); ACCESS_ARCHIVE; #ifdef USE_ARCHIVE//序列化函数 template<class Archive>void serialize(Archive & archive, const unsigned int version = 0){ archive &x; archive &y; }#endif T x;T y; }; } //包含内联函数文件#include "Point.inl"#endif

 

 namespace g{ template<class T> Point<T>::Point(): x(0), y(0) {} template<class T> Point<T>::Point(const T &x0, const T &y0): x(x0), y(y0) {} template<class T> Point<T>::Point(const Point<T> &point): x(point.x), y(point.y) {} template<class T>Point<T>& Point<T>::operator = (const Point<T> point) { x = point.x; y = point.y; return *this; } template<class T>void Point<T>::Swap(Point<T> &point){g::Swap<T>(x, point.x);g::Swap<T>(y, point.y);}template<class T>void Point<T>::Set(const T &x0, const T &y0){ x = x0; y = y0;}template<class T>void Point<T>::Clear() { x = 0; y = 0;}template<class T>bool Point<T>::operator ==(const Point<T> point){ return (x == point.x && y == point.y);} template<class T>Point<T>& Point<T>::operator -(const Point<T> point){ x-= point.x; y-= point.y; return *this; } template<class T>Point<T>& Point<T>::operator +(const Point<T> point){ x+= point.x; y+= point.y; return *this; } }  
  

序列化的例子如下：

#include <fstream>#include <iostream>#include <stdlib.h>#include <boost/archive/text_oarchive.hpp>#include <boost/archive/text_iarchive.hpp>#include "Point.hpp"#include "Math.hpp"using namespace std;int main(int argc, char *argv[]){ //目标文件 std::ofstream ofs("point.txt"); boost::archive::text_oarchive oa(ofs); //类实例 g::Point<int> point(200,2001); //类写入 oa << point; g::Point<float> pointf(-2.3,-2.334); oa << pointf; //档案关闭 ofs.close(); system("PAUSE"); return EXIT_SUCCESS;} 

 

当然这要在Point.hpp文件前面加个宏 #define G_USE_BOOST_ARCHIVE

 

然而这有个问题:  若 有个    

std::ifstream ifs("point.txt", std::ios::binary);
boost::archive::text_iarchive ia(ifs);
ifs >> pointf  will occur error..
