refactoring tutorial

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 pre-code Public class Registration { publicvoid Create (dec

This is my own experience in page refactoring, a set of rules to constrain their own CSS

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"; } }

MongoDB cluster refactoring, freeing up disk space Because MongoDB does not reclaim the corresponding disk space after deleting some of the data, it frees up disk space by rebuilding the data directory. an experimental environment A replica set is configured, which consists of the following three nodes: 10.192.203.201:27017 PRIMARY 10.192.203.202:27017 Secondary 10.192.203.202:10001 Arbiter Two experimental steps2.1 Simulation Environment Use DBA; fo

maintenance can be easily completed (no matter how many times the software undergoes changes and how many years it is maintained), To ensure that every change in future needs can be easily done (rather than bones). It is not easy to do these things, it requires us to continuously optimize and improve the internal quality of the system. This is the value of the system reconfiguration. In order to effectively improve the internal quality of the software, what should we do in the system

Hibernate refactoring DAO Ideas:First step: Implement generic DAO interface and implementation classCore technology:(1) When the new subclass () is called, the subclass invokes the constructor of the parent class, at which point the parent class can learn about the child class(2) Hibernate metadata, which is the data that describes the persisted class dataSecond step: For different table operations, inherit the DAO implementation class (in order to pa

During JavaScript refactoring, I hope to introduce an easy-to-use testing framework to ensure smooth refactoring. In the future, I will continue to use the testing code to ensure the correctness of the JavaScript logic.Http://sourceforge.net/projects/jsunit/,http://www.jsunit.net/ (JsUnit)JsUnit is an independent JavaScript unit testing framework, which is similar to JUnit and has no difficulty in getting s

Code refactoring is sometimes boring. String replacement and other operations are not only boring, but also prone to errors. Fortunately, some tools are available, taking 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. Let's start with a simple one. If we

Review above: Hybird Framework UI refactoring path: Iv. Divide and conquerHere are some of the key points of HTML and CSS in the development process.page structure in single page modeIn single-page mode, the concept of weakening HTML, the HTML as a container, body display of the main content is the page, an HTML container can hold 1 or more pages, each page is placed in the section. A page (section) must have a main content (content), or it may contai

C # asynchronous tool class and a little refactoring experience, The first article of the new year in 2015, wishing you a little late, but your sincerity is still at: Happy New Year. Today I want to share an asynchronous tool class. In the C/S architecture, I first perform asynchronous access to network resources and then call the callback function Invoke to the UI thread for UI processing. This is a common scenario. Therefore, a tool class is special

Background: A small project, probably design 10 pages, write demo mister did not give me design, all verbal, confessed, page style reference, as well as the interaction requirements. At first for the sake of the aspect, as well as the page associated content segmentation is not clear, I put the CSS,JS code all written in the page, inline. After the first edition is finished, Mister wants me to code optimization refactoring, very headache, mister requi

This period of time the message bus was re-refactored. This refactoring mainly focuses on the components of the message bus and the simplification of the pubsub client, as well as some ideas about the message bus. Simplifying the complexity of the clientThe previous client needs to connect two distributed components at the same time. Access to the message bus requires the user to provide the pubsuberHost pubsuberPort parameters, so it first connects

And find that this only brings trouble. The use of the time to refer to multiple DLLs, the development of the time there is no benefit. So a
