工厂方法模式(Factory Method Pattern),定义一个用于创建对象的接口,让子类决定实例化哪一个类,工厂方法使一个类的实例化延迟到其子类中。 二、解决的问题(What To Solve) 工厂方法模式较简单工厂模式,修改时关闭的,扩展时开放的,完全符合开放-封闭原则。工厂方法使一个类的实例化延迟到其子类中。 三、工厂方法模...
如果等级结构中只有一个具体工厂类的话,抽象工厂就可以省略,发生了退化。 六、 Factory Method模式与其它模式的关系 与工厂方法模式有关的模式还包括: 模板方法模式、MVC模式、享元模式、备忘录模式 七、 另外一个例子 //Factory Method pattern -- Real World example usingSystem; usingSystem.Collections; //"Pr...
Factory Method Design Pattern: Coding ExampleIn factory method design pattern mainly three classes/interfaces are involved, first, the factory class that creates an object from a given class hierarchy, second, an interface which is implemented by the concrete classes; objects of those classes will ...

ExampleThe Factory Method defines an interface for creating objects, but lets subclasses decide which classes to instantiate. Injection molding presses demonstrate this pattern. Manufacturers of plastic toys process plastic molding powder, and inject the plastic into molds of the desired shapes. The ...
In the Factory Method Pattern, a factory method defines what functions must be available in the non-abstract or concrete factory. These functions must be able to create objects that are extensions of a specific class. Which exact subclass is created will depend on the value of a parameter pass...

Simple Factory:Strictly speaking, it’s not a design pattern, but a technique we use very often. It encapsulates the object instantiation process. Factory Method:Defines an interface for creating an object, but let’s the classes that implement the interface decide which class to instantiate. The...
