System reconfiguration requires us to modify every step of the code, can not change the external behavior of the software, so in the system refactoring all the methods, is a kind of code equivalent transformation. The process of refactoring is like doing a math problem, step-by-step, the equivalent transformation of the formula. After a series of equal transformations, the final results are different in for

The result of code refactoring is criticalFor programmers, the meaning of refactoring does not seem to require much, and the clean code that is universally acknowledged is better.In a non-programmer-led project, refactoring requires more responsibility for the results, and once the refactoring brings more bugs and dela

that the subroutine should be placed in another class central and then called in the original class.11. excessive use of basic data types12. A class is idle , and sometimes refactoring of code can cause an existing class to have nothing to do. If a class looks like a misnomer, you should consider whether to pass the functionality of the class to other classes and then completely delete the class.13. a series of sub-procedures for transmitting data14,

Two project experiences At the end of 16, the maintenance of an old project was followed up, because the project was developed earlier and you know the various ways to do it. In the familiar with the code and in the follow-up to some specific tasks, often found that some code is not conducive to reading comprehension and add new features, if only one or two lines of code, I directly changed, but some longer code, because the time relationship is expected to be delivered as soon as possible, the

Follow the small series together to see it, hope to help everyone. 1. Refactoring and architecture Refactoring refers to rewriting the code without changing the behavior of the code, making it more concise and

This article will introduce the refactoring technique of "introducing local extension". Let's learn this refactoring technique.straight to Discovery: You need to provide some extra functions

When we begin to refactor the system, we do not start to modify the code, but first establish the test mechanism. No matter what the program, as long as we are modified, theoretically can introduce bugs, so we have to test. Since it's a test, you have to have a right or wrong standard of judgment. In previous tests, the criteria for their evaluation were whether they met business needs. As a result, testers often always hold the requirements document testing system. Unlike previous code modific

Whether in the iphone development or learning process will see some not very ideal code, it is undeniable that they are constantly "contributing" to this kind of code. In the face of some code "bad taste", refactoring is obviously an effective way to solve. The "reconstruction of the iphone" series wanted to summarize and supplement some of the refactoring that was going on in the development of the iphone,

LZ has been studying the Virtual Machine Source Code recently. Unfortunately, it's just a little bit of a clue. I can't share it with you. The huge Java Virtual Machine source code is really not something that can be done overnight, and LZ is excited. Aside from the relatively underlying Java Virtual Machine source code, LZ will discuss with you a few tips on code refactoring. This content is partly from books, it is partly from some practical experie

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

I will share with you some experiences on restructuring the JS front-end framework. If you are interested, don't miss it. After all, it's an experience. Let's get started. Refactoring is actually not a major action. The main function to be implemented is to re-divide the existing JS Code and decouple the existing modules. Then I plan to divide the existing program into modules and repackage it into a namespace to implement use or something similar to

PrefaceSome of the previous blogs have said rewriting and overloading, and today it is mainly about refactoring, by the way, by comparing the three.Refactoring , overriding, overloadingReconstruction is to improve the quality and performance of the software by adjusting the program code, so that the design pattern and architecture of the program are more reasonable, and the expansibility and maintainability of the software are improved. in layman's te

Application ScenariosI believe you have encountered this scenario:There are already a bunch of if-else or switch-case in the old code, and the product requires adding a new function to the process.What do people do at this time?My advice is to: Refactor this piece of code. On the basis of refactoring, new functions are added. Someone will say: The duration of the original tense, and then re-construction of the old code, will not

Today, we do not introduce specific refactoring techniques. Let's take a moment to look back and summarize what kind of code needs to be refactored and what kind of code has an "unpleasant smell" to suggest that we need refactoring to suggest that this code actually has an improvement. I also like the author of the code that the characteristics of the use of "bad taste", very image is also very vivid. Below

Today's refactoring has no fixed form. I have used different versions over the years, and I bet different people will have different versions. This refactoring applies to scenarios where the switch statement block is large and new judgment conditions are introduced at any time. In this case, we recommend that you use the policy mode to encapsulate each condition into a separate class. There are many ways to
