设计模式

//类适配器#include<memory>#include<iostream>using namespace std;class Target { public:virtual void request(){cout << "Target::Request"<<endl;}};class Adaptee{public: void SpecificRequest(){cout << "adaptee::SpecificRequest()"<<endl;}};class Adapter : public Target , Adaptee{public:void request(){Adaptee::SpecificRequest ();}};int main(int argc, char *argv[]){auto_ptr<Target> tarobj ( new Adapter() );//适配器就是引入中间类进行后台链接//Target *tarobj = new Adapter();tarobj->request ();return 0;}//对象适配器（比类适配器常用）#include<iostream>#include<memory>using namespace std;class Target{public:Target() {}virtual ~Target(){cout <<"delete target"<<endl;}virtual void Request(){cout << "Target request" << endl;}};class Adaptee{public:Adaptee() {}void SpecialRequest(){cout << "Adaptee::request" <<endl;}};class Adapter : public Target{public:Adapter() : m_Adaptee(new Adaptee()){}~Adapter(){if( m_Adaptee != NULL){delete m_Adaptee;cout << "delete Adaptee"<<endl;m_Adaptee = NULL;}}void Request (){m_Adaptee->SpecialRequest ();}private:Adaptee *m_Adaptee;};int main(int argc, char *argv[]){auto_ptr<Target> tarobj (new Adapter());tarobj->Request ();return 0;}
