设计模式之桥接模式(Bridge)

桥接模式与原理：将抽象部分与实现部分分离，使它们都可以独立的变化。最终的结果表现在实现类中。两者之间属于等价关系，即实现部分和抽象部分可以相互交换。

代码如下

#include <iostream>
using namespace std;
class OS
{
public:
	virtual void install()
	{

	}
};

class WindowsOS:public OS
{
public:
	virtual void install()
	{
		cout << "install windows OS" <<endl;
	}
};

class LinuxOS:public OS
{
public:
	virtual void install()
	{
		cout << "install linux OS" <<endl;
	}
};

class Computer
{
public:
	virtual void impInstall(OS* os)
	{

	}
};

class ComputerHP:public Computer
{
public:
	virtual void impInstall(OS* os)
	{
		cout<<"I am ComputerHP" <<endl;
		os->install();
	}
private:

};

class ComputerApple:public Computer
{
public:
	virtual void impInstall(OS* os)
	{
		cout<<"I am ComputerApple" <<endl;
		os->install();
	}
};

int main()
{
	OS* os = new LinuxOS();
	Computer *pcomp = new ComputerApple();
	pcomp->impInstall(os);
	return 0;
};
