Abstract Factory mode (alias: Package) Provides an interface to create a series of (interdependent) objects without specifying their specific classes. OverviewAbstract Factory method patterns can be used to design

the difference between a simple factory model and a factory method pattern The biggest advantage of a simple factory model is that the factory class contains the necessary logical judgments, dynamically instantiating the related classes according to the client's selection criteria, and to the client, the dependency on

ObjectiveImmediately after the previous article began to write, this is the second article in this series, this article mainly talk about the factory method mode. In the last article on the abstract Factory model, the three articles will be summarized.This article does not give a reflection mechanism to implement the code, mainly because the factory method mode i

Abstract Factory mode provides an interface to customers that enables clients to create product objects in multiple product families without having to specify a specific type of product.Design of the systemThe System class diagram is designed using the abstract factory model as follows:As you can see, the abstract factory pattern involves a role:Abstract

Factory method Mode (Virtual constructor/polymorphic Factory)The factory method pattern is the creation mode of the class, also known as virtual Construction sub-mode (Vsan Constructor) or polymorphism Factory mode (polymorphic Factory).The

5. Simple factory mode and factory ModeZookeeper 1 The core content of the simple factory model is: A: independent methods B: The factory does not.

2 Simple Factory mode Overview The simple factory model does not belong to the Gof 23 classic design pattern, but it is often used as the basis for learning other factory models, and its design concept is simple and its basic flow is as follows: The related code for the various objects that need to be created, such as various chart objects, is first encapsulated

The problem with factory method mode is that class creation relies on the factory class, that is, if you want to expand the program, the factory class must be modified, which violates the closure principle, so from the design point of view, there are certain problems, how to solve? Use the abstract factory pattern to c
