Understanding : Sometimes one of our methods requires a lot of parameters, too many parameters, not easy to read and understand, we can encapsulate multiple parameters into an object.Detailed :Refactoring Pre-code: 1 public class registration 2 { 3 public void Create (decimal amount, Student Student, ienumerabledecimal credits) 4 { 5 // do work 6 } 7 } It is often helpful to create a class of user-passed parameters in this case, w

Definition of refactoring:Refactoring is a kind of adjustment to the internal structure of software without changing the observable behavior of software.The goal of refactoring:1. The code is easy to read.2. All logic is specified only in the only place.3. The new changes will not be a crisis to existing behaviour.4. Express the conditional logic as simple as possible.The difference between refactoring and

Mind Mapping Introduced Re-organize your functions in the "refactoring-improve existing code Design" section of PHP above, and continue to talk about refactoring. Professional terminology Delegate: Delegate Encapsulate: Package Introduce: Introducing Objective "Deciding where to put the blame"-using refactoring to change the original desig

Refactoring is actually very simple. Its purpose is to make the program easier to understand, more maintainability, and more reasonable structure. Refactoring should be an essential part of code writing. For example, a better name for a function and splitting a large function into several small functions are all refactoring. The typical restructured books include

Reconstruction, in our Program The design is really very important. Its role, or even magic, can make us Code Vibrant and elegant. Because refactoring cannot be the syntax of the program language, there are few introductions to refactoring on the market, especially the authoritative book that truly makes a splash, we can only keep practicing and thinking in every practice. Taking my own

Signature Previously developed by the SharpDevelop team and used to sharpdevelop the refactoring plug-in in this open source IDE, "Nr6pack" was renamed "Refactoring Essentials" and was Hanselman called the "Web A compliment to Essentials "read the original text" to see Hanselman's introductory article, and I think the plugin will be one of the necessary plug-ins on visual Studio 2015 as well as Web Essenti

This paper analyzes 4 reasons for the difficulty in the maintenance and reconfiguration of PHP code. Share to everyone for your reference, specific as follows: Code maintenance, refactoring is a very unpleasant thing. In the following situations, it can be difficult to maintain and refactor code. 1. At the beginning of the project, we set some code norms, under a certain standard for development, but people's thinking is not the same, that is, each

It is a pity that he is very

I have been using intellij idea for Android development, and I feel quite comfortable. The latest intellij idea 12 (What's New ?) Released, including many new features. I have selected a feature related to the android development framework for you to introduce. The translation is as follows: Recently, we have added a new refactoring tool for the android XML layout file. All refactoring operations can now

Reconstruction background and causes Recently, due to the continuous expansion of the project team, the Code style in the project varies, and the project may be full of flowers or even anger. Taking into account the survival and development of the team, after many battles, the project team was finally decided to be divided into several teams based on the business to strengthen team management and improve efficiency, while also cultivating tiered talents. For the sake of "Uniform" code style, e

Namespaces are actually just a form, and the ultimate goal is to refactor the code, but it's impossible to do this in a single pass. At first, a pseudo proposition was given: thinkphp-based refactoring (not why). After a period of practice, it is found that this is a wrong way of thinking, in which the pits encountered in this slightly not table. First, don't try to rewrite the whole namespace based on namespaces, but should be local. The result o

Sometimes, when you encounter a large function, there are many temporary variables and parameters that make it impossible for you to extract method at all. Refactoring also strongly recommends the benefits of short functions, which bring about the explanatory, reusability of your benefits. But if you encounter a situation, you may be naïve to think that I just need to properly carry out the replace Temp with Query, you can resolve this phenomenon. But

Unit Testing of code refactoringCode refactoring that does not change the original function under the premise of modifying the relationship between the code, simply to make the code more concise, easy to read, maintainability is higher, does not weaken the original function of the program. An important subject in the refactoring process is unit testing--ensuring that every step of the modification does not

Just finished writing a part of the background function, now plan to refactor the code, but some questions, do not know how to deal with. Function Description:1. There are devices and groups under the user, devices can be grouped, and devices between groups can pass data to each other. Device on-line, find Redis has not cached users, groups, devices, if the cache is just a simple update of the cached individual data, if not so first look from the database, look after the Redis cache.2. Now is t

scenario is almost inevitable, how to solve it? Misunderstood MVC and deified MVVM put forward a solution to the idea of using MVVM, which is the process of passing data Viewcontroller to View, which is abstracted into structure ViewModel Process. After this abstraction, the View only accepts ViewModel, and the Controller only needs to pass ViewModel such a line of code. In addition to the process of constructing ViewModel, we can move to another class.In my opinion, this viewmodel layer is jus

In general, the source code to modify the framework is extremely risky, unless you have to, otherwise do not modify. But today, it is carefully reconstructed mybatis officially provided with spring integration of the Sqlsessionfactorybean class, one is to hold the mentality of trial and error, and indeed there is a real need. Let me explain two points: In general, refactoring is the optimization of code without changing functionality, but the

Concept | Website Refactoring we've been arguing about standards all these days. In fact, some of these issues have been made very clear. Let me just talk about my opinion. This post has too many "I think", explained that I just want to take out my ideas to discuss with you, perhaps there are too many wrong places, please point out. 　　 1, my understanding of the Web standards The so-called web standards have come to the conclusion in some tutoria

Legacy code is often rotten, and every good developer wants to refactor it. An ideal prerequisite for refactoring is that it should contain a set of unit test cases to avoid regression defects. But it's not easy to write unit tests for legacy code, because it's often a mess. To write a valid unit test for a legacy code, you probably have to refactor it first. But to refactor it, you need unit testing to make sure you don't break any functionality. Thi
