factory design pattern

Abstract Factory mode (Abstact Factory) is a common software design pattern. This pattern provides a unified creation interface for a product family. When you need a series of this product family, you can create a specific factory

The introduction recently saw a video explaining the. NET design pattern in Youtub, where one of the authors ' understandings impressed me deeply: the so-called design pattern is actually using object-oriented programming to solve the problem of tight coupling and low expansion in peacetime code. Another point of view

The role of design patterns in the design and development of object-oriented systems is like the role of data structures in process-oriented development. The importance and necessity of design patterns naturally do not need to be described in detail. However, the process of learning the design

Design Patterns (3) -- Abstract Factory patterns (Absrtact Factory Pattern), absrtactpattern Definition The essence of the abstract factory mode is to provide interfaces to create a series of related or independent objects without specifying the specific classes of these ob

GOF The book "Design Pattern" describes the abstract factory pattern: Provides an interface for creating a set of related or interdependent objects, and does not need to specify their specific classes. The general meaning is that when we create these objects, we do not need to specify their specific classes whose obj

A simple factory pattern is the creation pattern of a class, also called the Static Factory method (static Factory methods) pattern. The simple factory

To understand the design pattern correctly, we must first clarify what problems it proposes to solve.Abstract Concept of factory design patterns: For the abstract factory design model, I have found a lot of materials. I feel that

Abstract Factory modeUnderstand the factory method pattern, in fact, there are many similarities between abstract factory and factory method pattern. Abstract factories are also the separation of client object creation and logic c

Classification of plant design and design patterns: The factory model is divided into three categories in Java and mode:1) Simple Factory mode (simply Factory): not conducive to the production of products;2) Factory method mode (
