Abstract Factory patterns work around a super-factory which creates other factories. This factory is also called as factory of factories. This type of design pattern comes under creational pattern In Abstract Factory pattern an interface is responsible for creating a factory of related objects without...
Factory Patterns: Factory Method and Abstract Factory Design Patterns In Java Bob Tarr Factory Patterns l Factory patterns are examples of creational patterns l Creational patterns abstract the object instantiation process. They hide how objects are created and help make the overall system independent ...
每个产品家族的产品系列生产方法都要在 AbstractFactory 接口里面定义 总结 总的来说此模式在日常开发中使用频率不高,但关键时刻是能起大作用的。 设计模式值得你刻意练习! 源码 一如既往,你可以从GitHub上获得本文源码:design-patterns,星星点一下,猿猿不迷路。。。
Patterns Creational Pattern Learn in Java 1. Overview The Abstract Factory is a software design pattern whose goal is to provide a single interface to create families of objects with the same theme but without exposing the concrete implementation. This pattern provides another layer of abstraction ...
