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.

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我靠，这个婆婆也太碉堡了。Amateur "chefs" from around the country compete for a million dollar prize in the ultimate food fight.Through this practical activity in the countryside, we not only deepened our knowledge in practice, but also learned knowledge not found in books and received profound education.
