refactoring book

In the past few days, my task extracts a long method to make its code shorter, better understood, and better modified! In fact, this is the term Code refactoring! Reconstruction of local code is relatively simple, but it should be noted that you must conform to the existing architecture ideas and think within its scope. In fact, most of the reconstruction in this way is the extraction method, or the current Code Execution Process is reconstructed ba

most important consideration for modifying this method is the business logic commonly used in its class. /// /// Public Double Calculateinterestrate (){ If (Creditscore > 800 ) Return 0.02 ; If(Accountage>10)Return0.03; Return0.05;}} /// /// Interest /// Public Class Accountinterest{ Public Bankaccount account { Get ; Private Set ;} PublicAccountinterest (bankaccount account){Account=Account;} Public double interestrate {

C # refactoring skills Using the C # partial keyword, we can add the original class with the keyword partial, create a new class with the same name, and modify it with the partial. In the newly added class with the same name, we can start refactoring without having to sort out the original code and comment it out. Advantages of this approach: clear thinking, easy to manage new code. Disadvantage: None

Original English:Top 6 refactoring patterns to help you score 80% in code Quality In the past, I did a lot of code reading and found some common problems in code quality. The following areTop five: Bloated class:The reason why the class is bloated is that developers lack the most basic coding principle, namely the "single Responsibility Principle" (SRP. These classes tend to become very bloated because different methods that lack Association in func

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, eac

Refactoring can break down complex things into simple pieces. But sometimes you have to cut off the whole algorithm and replace it with a simple algorithm, and if you find that there is a clearer way to do something, you have every reason to solve the problem in a clearer way. If you start using libraries and find that the features in the library are duplicated with your code, you should also change your original algorithm. Or when you want to modify

In the previous article, I wrote a refactoring data structure, which is an example of the aggregation. One of the previous experiences was to refactor a long function, presumably to gather the relevant logic together. I call it logical aggregation. This is a process of refactoring the code logic.The story is like this. In my hand is a function consisting of hundreds of lines of code. The program seems to ha

paste the code of the current line. For example, when using stringbuilder. append, CTRL + D can simplify the work of Ctrl + C and CTRL + v.Once there was a key combination that could comment out the current row, and another one was to cancel the comment, but I forgot, because Ctrl +/should be the key that really belongs to it, click again to cancel the comment. With regard to resharper's refactoring functions, I may be naive to include many additio

An ASP. net project, because the system modeling stage is not fully considered, an inappropriate class name is given to a class. As a result, when the development is late, the names of the classes to be created are occupied. In order not to cause confusion in the future, I decided to change the class name for the previous class by matching the semantics with the entity as much as possible. In the past, JBuilder was used. It has the refactoring functi

Coderefactoring is sometimes boring. string replacement and other operations are not only boring, but also prone to errors. Fortunately, some tools are available. take PHP as an example, such as Rephactor, scisr and so on, but the ready-made tools often mean that they are not flexible enough, so today I want to talk about the application of Shell in code refactoring SyntaxHighli Code refactoring is sometime

When a method has more than 3 parameters, you can consider encapsulating the parameter as an object.Encapsulating the parameter as an object improves the readability of the code, and the Parameter object can be called by multiple methods, and if the delete parameter is added later, the method itself does not need to be modified, only the parameter object can be modified.

Refactoring: Code optimization, or you can understand the code changes!Example: Start your class name is a now change to B also known as a refactoring speciesOverloading: occurs in the same class, method names are the same , parameter lists are differentOverride: Occurs in a parent-child class where a subclass has a method name, and the parameter list and return value type are identical to the same method a

Before refactoring the code, you need to know what is HTTPS?HTTPS protocol: SSL/TLS-based HTTP protocol, all data is in theSSL/TLS protocol, which means that the HTTPS protocol is based on the HTTP protocolThe SSL/TLS handshake and the data encryption transfer are added, so this is the biggest difference between the two.The HTTPS module specifically handles encrypted access, except that SSL certificates are required to build an HTTPS server.Simulating

You want to replace an algorithm with another one that is clearer. Replace the function body with another algorithm. string Foundperson (string[] people) { for(inti = 0; I ) { if(People[i]. Equals ("Don")) { return"Don"; } if(People[i]. Equals ("John")) { return"John"; } if(People[i]. Equals ("Kent")) { return"Kent"; } }
