Loki 单键的使用

1.Loki的下载地址 http://sourceforge.net/projects/loki-lib/

2.把loki库考到自己的工程下

3.引入

#include "loki/Singleton.h"
using namespace Loki;

4.定义单键

typedef SingletonHolder<fish, CreateUsingNew, PhoenixSingleton> TheFish;

详细的代码如下：

animal.h

#ifndef ANIMAL_H_H
#define	ANIMAL_H_H
class animal
{
public:
	animal();
	~animal();
	void eat();
	void sleep();
	virtual void breathe();
};
#endif

animal.cpp

#include "animal.h"
#include <iostream>
using namespace std;
animal::animal()
{
}

animal::~animal()
{
}

void animal::eat()
{
}

void animal::sleep()
{
}

void animal::breathe()
{
	cout<<"animal breathe"<<endl;
}

fish.h

#include "animal.h"
#ifndef FISH_H_H
#define FISH_H_H
class fish:public animal
{
public:
	void breathe();
};
#endif

fish.cpp

#include "fish.h"
#include <iostream>
using namespace std;

void fish::breathe()
{
	cout<<"fish bubble"<<endl;
}

EX10.CPP

#include "animal.h"
#include "fish.h"
#include <iostream>
#include "loki/Singleton.h"
using namespace Loki;

using namespace std;


typedef SingletonHolder<fish, CreateUsingNew, PhoenixSingleton> TheFish;

void fn(animal *pAn)
{
	pAn->breathe();
}
void main()
{
	//animal *pAn;
	//fish fh;
	//pAn=&fh;
	//fn(pAn);
	TheFish::Instance().breathe();
	int n;
	cin>>n;
}
