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.

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
