设计模式-结构-Facade（外观）模式

Facade（外观）模式的作用是为各个子系统提供一个简明一致的接口，隐藏系统内部的复杂性，使子系统更加易用。它本质上是对一组子系统接口的统一包装。

class SubSystem1
{
public:
	void Operation(){}
};

class SubSystem2
{
public:
	void Operation(){}
};

class Facade
{
public:
	void OperationWarpper()
	{
		s1.Operation();
		s2.Operation();
	}
private:
	SubSystem1 s1;
	SubSystem2 s2;
};


int main(int argc, char *argv[])
{

	Facade *facade = new Facade;
	facade->OperationWarpper();

	return 0;
}
