Visitor pattern decouples the data structure from the operations acting on the structure, making the operation set relatively free to evolve. Visitor pattern is suitable for systems with relatively stable data structure and easy change of algorithm. Because visitor mode makes it easy to increase algorithm operation. If system data structure objects are easy to change and new data objects are often added, visitor mode is not suitable. The advantage of visitor mode is that it is easy to add operations, because adding operations means adding new visitors. Visitor mode centralizes the relevant behaviors into one visitor object, and its changes do not affect the system data structure. Its disadvantage is that it is difficult to add new data structures. -From Encyclopedia机灵鬼对少爷这一番高论十分佩服，觉得甚有道理。"As far as I understand it, If a mouse is the size of a domestic cat, But also rushed up in droves, It should be very dense, The goal is quite large, According to the weaponry at position 149, I don't feel too stressed, If you cooperate with the large "killer bees" to form an open space, you can also deploy some firepower to use tracer armour-piercing firebombs to the air and other weapons to the ground, whether it is a step machine gun, or rocket launchers, recoilless guns, as long as the command is proper, fire shooting, resist the attack of a group of mice, I think it is not too difficult? Is this kind of big mouse not only large in size, but also able to withstand bullet attacks? Or are they too fast to be easily hit? " I am somewhat puzzled by what Zhang Xiaobo said. He said his point of view, See if he has any answers, With the experience of strange dogs in position 142 interviewed earlier, Plus he just said that the rat moves quite quickly, So I preconceived that he would say that the reason why these mice are difficult to deal with is similar to that kind of strange dog, because the speed is fast and the movement is flexible, which leads to low fire killing efficiency and short reaction time, which leads to great pressure on position defense. As a result, I didn't expect him to give an answer that is not any one of my many assumptions:Carry Props Base Attack BonusSurgery and internal medicine are similar to general hospital physical examination, and the passing rate of initial examination is generally relatively high.身在楚地，东来本事楚人，尹旭自称大楚子民倒也算名符其实。常飞也在想：你个狗东西，敢杀上官，等回去老子要好好治你……可惜，他再也回不去了。
