C++设计模式之Prototype

namespace DesignPattern_Prototype
{
// class Prototype
class Prototype //抽象基类
{
public:
virtual Prototype* Clone() = 0 ;
} ;

// class ConcretePrototype1
class ConcretePrototype1 : public Prototype
{
public:
virtual Prototype* Clone()
{
ConcretePrototype1 *p = new ConcretePrototype1() ;
*p = *this ; //复制对象
return p ;
}
} ;

// class ConcretePrototype2
class ConcretePrototype2 : public Prototype
{
public:
virtual Prototype* Clone()
{
ConcretePrototype2 *p = new ConcretePrototype2() ;
*p = *this ; //复制对象
return p ;
}
} ;
}

客户端代码：
{
using namespace DesignPattern_Prototype ;

ConcretePrototype1 *obj1 = new ConcretePrototype1() ;//原型对象1
ConcretePrototype2 *obj2 = new ConcretePrototype2() ;//原型对象2

Prototype *newobj1 = obj1->Clone() ;//克隆对象1
Prototype *newobj2 = obj2->Clone() ;//克隆对象2

//使用复制出的对象newobj1和newobj2
}
