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他没等里面的人回答，自行补充道，来不及去西湖赏花了，我特邀戚将军秉烛小酌，你快些开门备酒菜。A new military strategyQingyuan MountainYang Liping Spokesman: 500,000 yuan per year Tang Zhenzong Spokesman: 500,000 Hong Kong dollars every two years
