Circle和Rectangle是具体桥梁类,它们继承了Bridge,实现了draw方法,将调用转发给实现类的fill方法。 在示例的最后,实例化了RedColor和GreenColor,并分别传递给Circle和Rectangle作为参数。然后调用了draw方法,输出了Circle和Rectangle的颜色填充。 通过桥接模式,将抽象部分和实现部分分离开来,可以使得它们可以独立地变化而互不...

In Python, you can use two general approaches to deal with resource management. You can wrap your code in: A try… finally construct A with construct The first approach is quite general and allows you to provide setup and teardown code to manage any kind of resource. However, it’s a ...
View Code 用一个简单的工厂类,来统一的提供给用户调用,根据用户提供的信息返回创建的实例。 2.工厂方法模式 在简单工厂模式中,我们只有一个工厂类,其中通过if else来判断需要创建什么对象,然后返回。 但我们想添加一个形状时,除了要实现相应的形状子类以外,还要修改这个唯一的工厂类。在if else判断语句中加一个分...
