python 设计模式之 (Chain of Responsibility)责任链模式,#写在前面对于每一种设计模式,如果不理解它的原理和结构,是写不出例子来的。所以弄明白很重要。等过完这段浑浑噩噩的日子,我要找个遍地开花的地方开怀大笑一场#责任链模式定义简书上一网友就把这个定义就说的挺
实现 有很多方法可以在Python中实现责任链,但我最喜欢的实现是Vespe Savikko。Vespe的实现使用Pythonic风格的动态调度来处理请求(http://j.mp/ddispatch)。 让我们以Vespe的实现为指导,实现一个简单的、基于事件的系统。下面是该系统的UML类图。 classEvent:def__init__(self,name):self.name=namedef__str__(s...
责任链模式(Chain Of Responsibility) Chain Of Responsibility? 这种情况下,我们可以考虑将多个对象组成一条职责链,然后按照它们在职责链上的顺序一个一个地找出到底应该谁来负责处理。 通俗:她告诉我们应该去“营业窗口”。然后等我们到了“营业窗口”后,又被告知应该去“售后部门”。等我们好不容易赶到了“售后...

职责链模式(Chain of Responsibility) 一、责任链模式介绍 责任链模式:将能够处理同一类请求的对象连成一条链,使这些对象都有机会处理请求,所提交的请求沿着链传递。从而避免请求的 发送者和接受者之间的耦合关系。链上的对象逐个判断是否有能力处理该请求,如果能则就处理,如果不能,则传给链上的下一个对象。 直到...
