?? If a person has not heard of the "refactoring" book, then he must not dare to say that he is a programmer; If a person has not read the "refactoring" book, it is hard to imagine that he will be a good programmer. This book is one of the three books that many companies require Java programmers to read (the other two books are "Java Programming ideas" and "effective Java"), which are irrelevant to the prog

Let's take a look at what's in the System refactoring Toolbox, which is to see how the system is refactored. System refactoring always adjusts our code at different levels, so the refactoring method is divided into several levels. In general, the reconstruction methods are divided into the following levels: reconstruction of methods, reconstruction of objects, re

How to "automate refactoring" of code For example: How to modify the method name of the code and its invocation? #!/usr/bin/env pythondef test(): test = 'test()' print test[:-2]test() Note:1. The IDE generally has such a function, it is hoped that the automated completion of the batch operation.2. Methods such as regular are not considered here, such as strings in the code with the same name can easily be replaced.3. The practice of the master

"One of the reasons is that the rules and guidelines discussed in this section are simple and easy." The second reason is that a simple and easy web design book, like a new free product in a supermarket, is a common but effective way to attract people's attention and encourage people to try.

The system reconfiguration is those system architect, the technology Daniel plays the high-end thing, our ordinary cock silk does not understand, has nothing to d

Introduction:When the architecture model is iterated, the model must be modified and improved. How can we prevent modifications to the model and ensure correct improvements to the model? Context After the architecture model is refined, merged, and other activities, it will be directly used for guidance.Code. At this time, some problems are often exposed. In actual coding, we usually find that the architecture exists or is large or small.Problems and errors, leading to the inability to contin

There are many refactoring methods. Relatively speaking, the coverage of an article cannot be mentioned. LZ can only propose some methods that are frequently used at ordinary times, if you are interested in some of the more advanced techniques, you can find some specialized books. In addition, because LZ is developed in JAVA, some refactoring tips may work with JAVA There are many

Software refactoring needs to be done with tools, and refactoring tools can modify the code and modify all the places that reference the code. This article collects five excellent PHP code

When you need to rename the package, class, method, range, local variables, and so on, please do not pass the search->replace ... or Search->replace in path ... menu, but should be done with refactoring. As mentioned earlier, because elements may already have many callers in one project, replacing the renaming will make it difficult to guarantee synchronous changes to definitions and invocations, while refactoring
