偷拍乱伦视频

压抑了很久，如今正好全面爆发，正渴望此战大胜，取得战功。恨不得掏出全部的身家来捐上。Brief description: when creating a new original class, value is initialized to egg, then modified to set the value to niu, and finally the penultimate row is restored to the state, and the result is successfully restored. In fact, I think this mode is called "backup-recovery" mode, which is the most vivid.In the above example, there is not much consideration for performance. In fact, there are some relatively large optimization points here.Decorator mode is also called Wrapper mode, which can dynamically add some additional functions to an object. Decorator mode is more flexible than the way of inheriting and generating subclasses. Although decorator mode can dynamically attach responsibilities to objects, it will also cause some small objects to be generated, increasing the complexity of the system. The specific structure diagram is shown below.
