大话设计模式迭代器模式c++实现

迭代器模式

其他二十三种设计模式

#include<iostream>
#include<vector>
#include<string>

//迭代模式
//--基本看的别人的
using namespace std;
typedef string object;

//抽象迭代器类
class Iterator {
   
   
public:
	virtual object First() = 0;
	virtual object Next() = 0;
	virtual bool IsDone() = 0;
	virtual object CurrentItem() = 0;
};
class ConcreteIterator;

//抽象聚集类
class Aggregate {
   
   
public:
	virtual Iterator* CreatIterator() = 0;
	virtual vector<object>* GetVector() = 0;
};

//具体聚集类
class ConcreteAggregate :public Aggregate {
   
   
public:
	ConcreteAggregate();
	~ConcreteAggregate();

	virtual Iterator*
