Visitor mode is to encapsulate some operations applied to a certain data structure. Once these operations need to be modified, the data structure that accepts this operation can be saved unchanged. Visitor mode is suitable for systems with relatively stable data structures. It reduces the coupling degree between data structures and operations acting on data structures, making the set of operations relatively free to change. The specific structure diagram is as follows:　　Season 3, Episode 6: The Priory School《修道院公学》13 August 1986本剧改编自Dolly Alderton的同名畅销回忆录，聚焦两个童年密友，Maggie (Emma Appleton饰)和Birdy (Bel Powley饰)。故事以2012年伦敦的合租房为背景，混合对21世纪初郊区青春期的回忆，毫不掩饰地深入探讨了糟糕的约会、心痛和羞辱。哦，蔬菜有炒藕片、凉拌黄瓜、炒青椒……他细细地回想，难道这些菜有不相宜的品类？秦枫一声不吭，探手为他号脉。This paper mainly analyzes Reactor mode in detail. Netty uses Reactor mode to realize asynchronous event-driven network application framework, so it is very important to master Reactor mode in Netty's learning.Appearance mode focuses on simplifying interfaces and simplifying the dependency relationship between component systems and external client programs.或许这就是蛮人的独特之处吧，意想不到地就归顺了自己，而且还表面的如此的忠诚。
