In the above code, we use three functions, order500, order200, orderNormal to handle its own business logic, If the current own function cannot handle things, We pass it to the following function to handle it. By analogy, Until there is a function that can handle him, Otherwise, the responsibility chain mode will leave the chain directly, telling that it cannot be processed and throwing an error prompt. Although the above code can be used as the responsibility chain mode, we can see from the above code that the Order500 function depends on functions such as Order200, so there must be this function, which also violates the open-closed principle in object-oriented. Let's continue to understand writing flexible and detachable responsibility chain nodes.哎呀。西天取经五百年后，如来圆寂，金翅大鹏祸乱三界。孙悟空为拯救三界，口含如来舍利降世人间。在召集师弟沙悟净、朱悟能的过程中，悟空终于领悟舍身取义的无量佛法，蜕变真身，消灭蛤蟆精，踏上打败金翅大鹏的西行路。故事设定在夜神月与L对决十年之后，世界上发生死亡笔记大量杀人事件，日本死亡笔记对策总部特别小队查出世界上共有六册死亡笔记，围绕这六册死亡笔记，全世界被卷入终极头脑战。书呆子艾略特出身显赫的将军世家，母亲则是鼎鼎大名的人类学家。为了逃离虎妈的控制，艾略特独自申请到博士奖学金，前往世界上最危险的亚马逊寻找传说中的乌托皮族。原以为这是人类学家就近观察原始部落的好机会，没想到乌托皮的头目竟然是个女的，她不但有手机，而且抽菸、酗酒样样来！女头目狂放不羁的野蛮特质深深吸引了他，艾略特从一介书虫，摇身一变成为一代毒枭斜槓压榨劳力的资本家，以科学化的方式提高乌托皮族淘金的产能，好让他们可以去「老王杂货店」血拚个够。另一方面，虎妈赶来南美洲万里寻儿，一帮智商堪忧的法国军队成了她的猪队友，爱子还没找到，却沿路招惹了邻国军队、莫名其妙在「老王杂货店」引发枪战。究竟在这原始的亚马逊丛林裡藏著什麽不可告人的秘密？而母子俩又能不能逢凶化吉展开大和解呢？"Well, This is basically the case, After they all flew, they stayed in the air for a while.
