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

本剧以南宋时代，临安附近（今杭州市），济公少年悟道之后，四十来岁的一段遭遇为主题，话说当年宋朝北面江山不保，被金人赶杀，偏安江左，随着朝廷南迁的有大批难民，富商、仕官，社会形成两极化，富者极富，贫者极贫。当时人心极度不安，不知金人何时会南渡，更因官商勾结，抱着极短视的态度，搜刮无度，不理人民疾苦，因此民间弥漫着一种极不平的气氛。这时民间出现了一个奇人怪僧，人称济颠，其行为放荡不羁，言行奇特，游戏人间，疯疯癫癫的，十足一个颠和尚。但其实他的心一点也不颠，他的智慧一点也不疯，他不贪财，不攀缘，不谈神，不说怪，就是扶危济倾，医人医世，施诊赠药，为人解决疑难，到处点化不平人，为人解决不平事。但是济公也有无能之处，就是爱情问题。因济公从未经历过，所以男女情为何物，一点也不知。济公为了体会，为了历练〝爱情的魔力〞竟然曾经想过勇闯情关，结果苦到不得了。
汉武帝刘彻为太子时，结交了布衣之交张汤（张固）、灌夫（关夫）、李陵（李勇）、郭舍人（郭德仁）等。一群年青人自视为"太子党"，怀着建功立业的共同梦想。而刘彻祖母太后窦漪却因维护窦氏外戚家族既得利益，千方百计欲废掉太子刘彻，让小儿子梁王刘武取而代之。 黑幕重重，罗网向刘彻一伙撒来。刘彻身处险境而不自知，沉湎在青春的爱情追求中。而刘彻偶尔相识的奇人东方朔，几次指点迷津，使他们屡屡有惊无险、逢凶化吉。最后使刘彻棋先一着，登上皇帝宝座。汉武帝少年登基，依靠东方朔（东方慧）和"太子党"们排除了窦太后等后宫势力。汉武帝奋发图强，又内平叛乱，北胜匈奴，结束了只靠"和亲"维持屈辱和平的七十年汉朝历史，把汉朝推向最强盛的峰巅。
