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

An unlikely trio traverses a desert planet in search of a rumored lake- and the hope for a better life that it represents. Lernert travels across the barren landscape, digging through rubbish piles in an attempt to build a body for Susan, the robot head who hangs, unresponsive, from the back of his pack.

At first unwilling to travel together, the three-some navigate the harsh desert in search of a mythical water basin that can replenish their depleted resources and their will to continue.

Analysis, on the other hand, is to conduct a more detailed study of the contents of a class and find their subtle and accurate differences so as to have a deeper understanding of things. It is a comprehensive ability to see that some of them have more connections and more common points from the numerous and complicated large number of things, so that they can be summed up together to make the large number of things that were originally scattered form systems and categories.
