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本剧讲述蛇精与人相恋的故事，不过，这个故事并非《白蛇传》，没有水浸金山及士林祭塔，但有蛇精。 剧中的蛇精亦是青蛇和白蛇，两蛇情同姊妹，幻化人形，在“灵雨山庄”中过着逍遥自在的生活。两蛇巧遇穷书生宁丹，被他的翩翩风度吸引，齐齐堕进情网。两蛇先后与宁丹发生关系，亦因此而成为仇敌，青蛇为了成全白蛇，黯然怀着宁丹的骨肉远走高飞。两蛇后来均为宁丹诞下骨肉，又加入黑蝙蝠的作恶，于是高潮迭起，深深吸引着观众追剧情的兴趣，其结局更与一般的神怪片廻异，未至剧终，也难猜度出来。Rocket launcher (mine x 10)2017-02-01 10:35:34The parameter of the function cannot have a property with the same name, otherwise an error is reported.失恋疗养院是一家专门负责帮助恋爱中受伤的人走出低谷，开始新生活的工作室。李小明是疗养院负责人，王子宁介绍闺蜜安冉与李小明认识时，安冉刚和相恋七年的男友朱永在领证前夕分手。安冉失恋，工作和生活陷入低谷。在李小明的帮助下，安冉入住失恋疗养院，开始寻找新生之路。在疗养院里，安冉结识了大虾，丁丁，香肠弟等一群困于情感伤害的善良之人。不断相处中，他们相互安慰，彼此鼓励，重拾对爱情的信心，重建积极健康的爱情观，慢慢找回自我价值，开始新的生活。
