　　Recently read the "HTML refactoring" this book, the following to make their own summary, we can learn to communicate together.What is refactoring? Refactoring is a process in which code is gradually perfected without changing the behavior of the program, and usually requires some help from the automation tools. A good site is a need for us to make perfect impro

Objective Refactoring (Refactoring) is a process that modifies code to improve the internal structure of the program without altering the external behavior of the code. Refactoring is a disciplined and methodical process of organizing, which minimizes the chance of introducing errors in the process of finishing. 1th Chapter Reconstruction, the first case (slightl

PHP Code Maintenance, refactoring 4 reasons for difficulty analysis, 4 kinds of cause analysis This paper analyzes the 4 reasons why PHP code maintenance and refactoring becomes difficult. Share to everyone for your reference, as follows: Code maintenance, refactoring is a very unpleasant thing. The following scenarios make it difficult to maintain and refactor

It has been a long time since Martin Fowler first proposed the concept of refactoring. It is not so much a method as an idea and a habit. I have been using it to improve my work.ProgramSo I want to talk about my two points here. Rebuilding is not "picky eaters" As mentioned above, refactoring is not only a fixed method, but also a habit of thinking and coding,No matter which language you program, you ca

. The same modification to the inheritance system10. The case statement must be modified in the same way.11. The data used at the same time is not organized in the form of classes.If you see that you often operate on the same group of data, you should also ask yourself whether you should put the data and its operations Organized into a class.12. member functions use more features of other classes than their own classes.This implies that this subroutine should be put into another class and then

In software engineering, the term refactoring code usually refers to modifying the source code without changing the external behavior of the code. Software refactoring needs to be done with tools, and refactoring tools can modify the code while modifying all the places that reference that code. This article has collected five excellent PHP code

There are many ways to refactor code. Many people think that refactoring code should be put in the backlog. But in fact, this is not an ideal method.　　At the beginning of the project, your code is clean.　　Even if there is a need for a small detour, but this time we can easily and smoothly add functionality. This stage is generally not a problem, and because we are more anxious, so even if there are some small problems, we will not notice.　　However, as

1 Introduction Refactoring plays an important role in the process of modern software development, it can reduce the workload of software developers and improve the productivity of software development. To illustrate the importance of refactoring, here's a quote from the tutorial on refactoring provided by David Carew on Developerworks: Now, a developer's job is

procedural style in hand.Turns the data record into an object, divides a chunk of rows into small chunks, and moves the behavior into the related object.4. Separate domain from Presentation separates the domain from the presentation/display: Some GUI classes contain domain logic. Separate domain logic and create separate domain classes for them.5, Extract Hierarchy refining the Inheritance system: you have a class that does too much work, and part of it is done with a lot of conditional express

?? If a person has not heard of the "refactoring" book, then he must not dare to say that he is a programmer; If a person has not read the "refactoring" book, it is hard to imagine that he will be a good programmer. This book is one of the three books that many companies require Java programmers to read (the other two books are "Java Programming ideas" and "effective Java"), which are irrelevant to the prog

Let's take a look at what's in the System refactoring Toolbox, which is to see how the system is refactored. System refactoring always adjusts our code at different levels, so the refactoring method is divided into several levels. In general, the reconstruction methods are divided into the following levels: reconstruction of methods, reconstruction of objects, re

How to "automate refactoring" of code For example: How to modify the method name of the code and its invocation? #!/usr/bin/env pythondef test(): test = 'test()' print test[:-2]test() Note:1. The IDE generally has such a function, it is hoped that the automated completion of the batch operation.2. Methods such as regular are not considered here, such as strings in the code with the same name can easily be replaced.3. The practice of the master

Introduction:When the architecture model is iterated, the model must be modified and improved. How can we prevent modifications to the model and ensure correct improvements to the model? Context After the architecture model is refined, merged, and other activities, it will be directly used for guidance.Code. At this time, some problems are often exposed. In actual coding, we usually find that the architecture exists or is large or small.Problems and errors, leading to the inability to contin

There are many refactoring methods. Relatively speaking, the coverage of an article cannot be mentioned. LZ can only propose some methods that are frequently used at ordinary times, if you are interested in some of the more advanced techniques, you can find some specialized books. In addition, because LZ is developed in JAVA, some refactoring tips may work with JAVA There are many
