Design Pattern-builder Pattern The builder mode is Separate the construction of a complex object from its representation so that the same construction process can create different representations. this means that the construction of a complex object is separated from its representation, so that different representations can be created during the same construction process. The
Some people who know siwft know that ring is a very core component of swift and determines how data is distributed in the cluster. Swift determines the number of partitions in the Cluster Based on the configured partition_power (2 to the power of partition_power), and based on consistent hashAlgorithmAllocate partitions to different nodes and distribute data to corresponding partitions. Therefore, building a ring is a process that swift initialization must go through. Simply put: New R
defines The Separates the build of a complex object from its performance so that the same build process can create different manifestations. The look at this concept, may feel very abstract, can understand but do not know what use. Let's make an analogy to understand the definition above. Before we make a metaphor, let's talk about what this design pattern is for. Why do we use this model? The builder model is responsible for decoupling th
Design Mode (9) --- builder mode, design mode --- Construction I. Definition Builder mode: separates the construction of a complex object from its representation, so that different representations can be created during the same build process. Explanation: In the builder mode, you only need to specify the types to be constructed to obtain them, but you do not need
Builder Mode)Definition (After reading the Chinese and English versions of this book, I found that I have learned nine tricks about the builder model, So I went online to search for others' analysis, therefore, this chapter mostly collects data from the Internet. In addition, code examples indicate that the examples in this book are inappropriate and have changed, so this chapter has little to do with this
Overview In a software system, sometimes it is faced with the creation of "a complex object", which is usually composed of sub-objects of each part using a certain algorithm; due to changes in requirements, the various parts of this complex object often face drastic changes, but the algorithms that combine them are relatively stable. How to deal with this change? How can we provide a "encapsulation mechanism" to isolate the changes of "various parts of complex objects", so as to keep the "stable
[Design mode] javascript builder ModeBuilder mode description 1. separates the construction of a complex object from its representation so that the same creation process can have different representations. This is called the builder mode. 2. description in object-oriented language. Main roles: 1>. the Builder interface class defines the Builder's [Worker] and uni
I have read this book about objective Java Distilled: "objective Java" intermittently for nearly two times. The content in this book is quite deep and is very helpful for improving the quality of engineering code. I plan to organize a series slowly. The reason why I name it objective Java Distilled is to organize the essence of this book as much as possible to facilitate review and use. After all, my memory is limited and many things are often forgotten. Of course, it would be better if it could

So I want to tell you why and when you should consider using the design pattern

Problem: If we want to write a builder class, we can write as follows: Class Person { Public: Void BuildHead (); Void BuildBody (); Void BuildArmLetf (); Void BuildArmRight (); Void BuildLegLeft (); Void BuildLegRight (); }; But what should we do when we want to build a thin, fat, and tall person? Of course, we will think of defining the class of the builder above as an abstract class, and then defining t

Introduction to Builders ' modelsThe builder pattern separates the construction of a complex object from its representation, allowing the same build process to create different representations. In other words, the build pattern is the object's creation pattern. The construction mode separates the internal representation of a product from the production process of the product, allowing a construction process to produce objects with different internal r
