六、 Abstract Factory模式在实际系统中的实现 Herbivore:草食动物 Carnivore:食肉动物 Bison:['baisn],美洲或欧洲的野牛 下面实际代码演示了一个电脑游戏中创建不同动物的抽象工厂。尽管在不同大陆下动物物种是不一样的,但动物间的关系仍然保留了下来。 //Abstract Factory pattern -- Real World example usingSystem...
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 ...
Pattern denotes a design, factory denotes the location of product production, and abstract denotes the concealment of certain information. Thus, a software design pattern known as the Abstract Factory Pattern offers a means of encapsulating a collection of distinct factories that have a common theme....
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,...
Design Pattern - Abstract Factory Pattern - 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 as this patte
The abstract factory is a GOF (Gang of Four) creational pattern where the intent is to "...provide an interface for creating families of related or dependent objects without specifying their concrete classes". ("Design Patterns" -- Gamma, Help, Johnson, Vlissides) ...
Back to Abstract Factory description Applications in DelphiThis pattern is ideal where you want to isolate your application from the implementation of the concrete classes. For example if you wanted to overlay Delphi's VCL with a common VCL layer for both 16 and 32 bit applications, you might...
设计模式抽象工厂MISThis article from the design pattern, analyzed the abstract factory pattern (Abstract Factory Pattern), the abstract factory design pattern in a hierarchy application of distributed systems, and abstract factory design pattern to management information system (MIS). Abstract factory ...
Abstract Factory 抽象工厂 Intent 意图 Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes. 抽象工厂是一种创建性设计模式,它允许您生成相关对象的族,而无需指定其具体类。
