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佟李氏很早就失去了丈夫，和女儿大香过着相依为命的生活。孤苦伶仃的母女两人进城投奔舅母孙大妈，就此结识了名为尚幼林的男子。善良的尚幼林常常帮助生活困苦的佟李氏，一来二去之间，两人之间渐渐产生了真挚的感情。玉米眼睛一亮，忙把小手往缝隙里一插，两手各钩住一根木头，再把两脚往床头土坯空处一搭，整个身子就悬空贴在床底了。
