抽象工厂模式(Abstract Factory Pattern)是围绕一个超级工厂创建其他工厂。该超级工厂又称为其他工厂的工厂。这种类型的设计模式属于创建型模式,它提供了一种创建对象的最佳方式。 在抽象工厂模式中,接口是负责创建一个相关对象的工厂,不需要显式指定它们的类。每个生成的工厂都能按照工厂模式提供对象。

下一步是创建抽象工厂类 AbstractFactory。接着定义工厂类 ShapeFactory 和 ColorFactory,这两个工厂类都是扩展了 AbstractFactory。然后创建一个工厂创造器/生成器类 FactoryProducer。AbstractFactoryPatternDemo 类使用 FactoryProducer 来获取 AbstractFactory 对象。它将向 AbstractFactory 传递形状信息 Shape(CIRCLE / ...
Abstract Factory classes are often implemented with Factory Methods, but they can also be implemented using Prototype. Abstract Factory might store a set of Prototypes from which to clone and return product objects.Factory Method: creation through inheritance. Prototype: creation through delegation. Vi...

抽象工厂模式(Abstract Factory Pattern): 抽象工厂模式提供一个接口,用于创建一系列相关或相互依赖的对象。客户端通过使用抽象工厂及其产品接口来创建对象,从而将客户端与具体的产品实现解耦。 优点 客户端通过抽象工厂接口来创建对象,可以轻松替换不同的具体工厂,实现不同产品族的切换。
