Prototype模式通过复制原型（Prototype）而获得新对象创建的功能，这里Prototype本身就是“对象工厂”
prototype.h：
#ifndef _PROTOTYPE_H_
#define _PROTOTYPE_H_
class Prototype
{
public:
virtual ~Prototype();
virtual Prototype* Clone() const = 0;
protected:
Prototype();
private:
};
class ConcretePrototype:public Prototype
{
public:
ConcretePrototype();
ConcretePrototype(const ConcretePrototype& cp);
~ConcretePrototype();
Prototype* Clone() const;
protected:
private:
};
#endif //~_PROTOTYPE_H_
prototype.cpp：
#include "prototype.h"
#include <iostream>
using namespace std;
Prototype::Prototype(){
}
Prototype::~Prototype(){
}
Prototype* Prototype::Clone() const{
return 0;
}
ConcretePrototype::ConcretePrototype(){
}
ConcretePrototype::~ConcretePrototype(){
}
ConcretePrototype::ConcretePrototype(const ConcretePrototype& cp){
cout<<"ConcretePrototype copy ..."<<endl;
}
Prototype* ConcretePrototype::Clone() const{
return new ConcretePrototype(*this);
}
main.cpp：
#include "prototype.h"
#include <iostream>
using namespace std;
int main(){
Prototype* p = new ConcretePrototype();
Prototype* p1 = p->Clone();
return 1;
}
