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面上却一点不显，连顿一下也没有，先呵呵大笑两声，才道：这是自然的，我们母子一向心意相通。为使明军首尾不能兼顾，此番鬼倭攻城并不像先前那样随性，两队人策马围城包夹，伺机待发。LinearLight《谢文东 第二季》再掀江湖风云，看东哥如何愈战愈强，带领文东会登上江湖顶端……杨蓉站了起来，一脸严肃的向陈启行一个礼。
