In the previous example of electric lights, a state mode program was completed. First, the Light class is defined, which is also called Context here. Then in Light's constructor, to create instance objects for each state class, Context will hold references to these state objects in order to delegate the request to the state objects. The user's request, that is, the action of clicking button, is also implemented in Context, with the following code: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［Season2（30分×全9話）］Season1 放送終了後、動画配信サービス「Paravi（パラビ）」にて配信1月17日（木）深夜24時26分から配信スタート（以降、毎週水曜24時配信）《惩罚者》（Marvel's The Punisher，或简称：The Punisher）是漫威电视联合ABC电视台为NetFlix打造的真人超级英雄剧集，改编自漫威同名漫画，是漫威电影宇宙的一部分，也是《超胆侠》的衍生剧，由安迪·戈达德等人执导，乔·博恩瑟、本·巴恩斯、爱波·莫斯-巴克拉赫、艾波·罗丝·雷瓦等主演。童星出身的人气女星林羽潼，是话题女王，因为各种莫名其妙的事情总是被动地上头条。林羽潼的爸爸是一名电影导演,在羽潼8岁时得重病离世，与母亲也因为误会分开。跟着金牌经纪人赵东来长大的她，养成了孤傲的性格。嫉恶如仇的她得罪了不少人，招了不少黑粉，而她自己又不爱解释和妥协。见过了娱乐圈各种是是非非的林羽潼，依然保持着自己的初心-------认真演好每一部戏，成为一个被大家认可的好演员。某天经纪人签了个菜鸟新人尚佳佳，两人逐渐成为朋友。林羽潼带着尚佳佳见识到了娱乐圈的诸多样貌。林羽潼虽然遭遇过事业的各种危机，但都事出有因，所以最后都能得到解决。直到有一天因为一场车祸被司机作伪证是杀人凶手，身败名裂...他们好不容易搞到一辆车，为了逃到安全地带，这几个幸存者踏上充满凶险的求生之旅……4.
