抽象工厂设计模式(Abstract Factory Design Pattern)是创建型模式之一。抽象工厂设计模式类似于工厂设计模式(Factory Design Pattern),但是它更像工厂的工厂。 Abstract Factory 如果你比较熟悉工厂设计模式(Factory Design Pattern),你会注意到有一个单独的工厂类,这个类负责根据提供参数的不同实例化并返回不同的实现类,...
The essence of the Abstract Factory Pattern is to "Provide an interface for creating families of related or dependent objects without specifying their concrete classes" 抽象工厂为创建一组相关或者是相互依赖的对象提供一个接口,而不需要指定他们的具体类 使用场景 如果你的业务中出现了要依据不同的产品家族...
{ ENGINOLA, EMBER } abstract class AbstractFactory { private static final EmberToolkit EMBER_TOOLKIT = new EmberToolkit(); private static final EnginolaToolkit ENGINOLA_TOOLKIT = new EnginolaToolkit(); // Returns a concrete factory object that is an instance of the // concrete factory class ...
Back to Abstract Factory description Discussion. "Think of constructors as factories that churn out objects". Here we are allocating the constructor responsibility to a factory object, and then using inheritance and virtual member functions to provide a "virtual constructor" capability. So there ...
import com.journaldev.design.model.Computer; public interface ComputerAbstractFactory { public Computer createComputer(); } 注意createComputer返回的是超类(super class)Computer。现在我们的工厂类实现这个接口,并返回各自的子类。 PCFactory.java package com.journaldev.design.abstractfactory; ...
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...

从Factory Method&Abstract Factory开始。 一、Factory Method 工厂方法模式的用意是定义一个创建产品对象的工厂接口,将实际创建工作推迟到子类中。 我们的例子如下: 我们项目中有一个代码提交记录releasenote,我们需要将这个releasenote分成csv/xls/xml格式分别导出 ...
