ObjectiveThis article may be more difficult to understand for most of the friends who do not know Enode, this article focuses on ideas, not on the results. I write articles, always hope to be able to put their own thinking process as far as possible to express, can let you know every design behind the thinking of things. I think that the result of any design may look very tall, a picture can be, but the thinking behind, is more valuable things.This article wants to write about how Enode handles

In the previous series of articles, I was concerned about re-organizing your function in one of the PHP Miscellaneous "refactoring-improving the design of existing code", but I still didn't think I made it clear, I also have a lot of points that I don't understand, and this is my first article in this regard. There are a lot of mistakes, so I will make frequent changes, if you have good comments, let us know the first and second mind map. Introduct

Last night the book named [Data Structure with Java hubbed] was closed. when talked about the advantage that I have taken of, with the help of that book I familize myself with data structure, especially the Java Collection framework. I think it important for me to further get my position promptation. so today night I prepare to start a new book, whose name is Opdyke, Don Roberts. in the past this book was always talked by friends and was strongrong recommended to me as a primary guigude to Sen

The initial exposure to object-oriented CSS is due to the fact that there are more than 8,000 lines of CSS in the project, lack of constraints and management, and there is a compelling need for refactoring in the near future or not far away. In front-end refactoring, we've talked about JavaScript object-oriented refactoring, and at this point look at CSS object-o

authentication is a means, not an end Sometimes, we use JavaScript to generate Flash movie code to deceive validator and pass validation. In this way, there are no validated pages. If it's just a play, it's OK. But I am afraid some beginners will take validator seriously, even think that through verification is the ultimate goal. My view is: Validator is just a tool that helps us check if our pages are up to standard, that's all. In the end we still have to design our page according to the cus

There's a morning share. Repeater control Dynamic Change column (Header,item and foot) information is dynamically changing the contents of some columns. Although it is not completely dynamic, it has reached the initial desired effect. If you are careful, you can easily get it out. Now open another, insus.net is not another write, but want to refactor the CS code, because the previous piece of code, although simple, but too much code redundancy.Refactoring start:First, delete these five variable

There are three main types of refactoring for Java code: Renaming method refactoring mode, introducing explanatory variable reconstruction mode, replacing temporary variable reconstruction mode with query Renaming Method Refactoring mode recommends performing the following steps to complete : 1.

In the process of object-oriented programming, clarify the responsibilities of this object. Class should be: do what you should do, do what you should do, 1. Move Method Move Function Class behavior to achieve a single responsibility do not go beyond the Proxy: In your program, there is a function to communicate with another class outside of the resident class: Call the latter, or be called by the latter. Create a new function with similar behavior in the class most commonly referenced by this f

Simplify function calls 1. Pull Up Field move Up The two subclasses have the same field. Move this field to the superclass. If the child classes are developed separately or combined during the refactoring process, you will often find that they have repeated features, especially for fields that are more likely to be repeated. Such fields sometimes have similar names, but they are not absolutely the same. The only way to determine whether several field

Recently took over a project, the source code of the architecture and many designs have a bad taste. You want to refactor, but you don't have enough clout.First, the restructuring of the tangle:(1) If the existing code is available, will your refactoring be more efficient than it is now?(2) The project progress is relatively tight, do you want to spare time to do such a job without KPIs;(3) After you re-construct, others need to re-read your source co

03 Refactoring _ Improve the design of existing code reading notes of the thirdThe main features of this book are:Refactoring is the process of modifying a program at a small pace, and if you make a mistake, you can easily find it.Any fool can write code that can be understood by a computer. The only good programmer is to write code that is easy for human to understand.Refactoring (noun): an adjustment to the internal structure of software to improve

{ return set.numOfComponents}func (set *QuickUnionSet) IsConnected (p, q uint) bool { return set.Find(p) == set.Find(q)} The author says he always wants to eliminate repetitive code when programming, and in other languages it can be done with class or macro, and he wants to know how to do better in the go language. in fact, here's another question: Is there a need for refactoring to eliminate duplicate code? Or, what kind of situation requires

This time to bring you a summary of the PHP code refactoring methods, PHP code refactoring considerations are what, the following is the actual case, take a look. As PHP transforms from a simple scripting language into a mature programming language, the complexity of a typical PHP application's code base increases. To control the support and maintenance of these applications, we can use a variety of test t

Well, the fifth chapter of the book, "Refactoring," is a description of the writing structure of some concrete refactoring techniques that are about to be written, and nothing important.As if to celebrate New Year's Day holiday, specially prepared for me chapters, in order to let me complete today's task and deliberately water a chapter.Well, there's one important thing: Design pattern

Code refactoring is sometimes tedious, and string substitution is not only tedious, but also error-prone, with some tools available, PHP for example, REPHACTOR,SCISR and so on, but ready-made tools often mean inflexible So today I'm going to talk about the application of shell in code refactoring. First of all, let's say we want to replace all the Foo_bar in the php file with Foobar, so we can do the follo
