c++ 类中模版成员函数
C++函数模版与类模版。
template <class T> void SwapFunction(T &first, T &second){ }//函数模版
template <class T>//类模版
class CTemplate{
public:
void SWap(T &first, T &second){
}
};
#include <iostream> class Single{ public: static Single* ShareInstance(); static void ReleaseInstance(); template<class Tex>//要成员函数实现模版用法,而类不是模版类。需要写成这个格式 void SwapEx(Tex &obj1, Tex &obj2){ } private: Single(); ~Single(); Single(const Single &other); Single& operator=(const Single &other); private: static Single *m_pObj; }; Single* Single::m_pObj = NULL; Single* Single::ShareInstance(){ if (NULL == m_pObj) { Single obj; m_pObj = new Single(); } return m_pObj; } void Single::ReleaseInstance(){ if (m_pObj) { delete m_pObj; m_pObj = NULL; } } Single::Single(){ } Single::~Single(){ }
