After the previous explanation, I believe you have some preliminary understanding of the system reconfiguration. Everything seems to tell us that system refactoring always has nothing to do with changing requirements. But at this point, I have to tell you this is a true lie. Our software system is always in a change, and often is a process from easy to difficult. However, when the complexity of the system changes, we should adjust our design in time

Two project experiences At the end of 16, the maintenance of an old project was followed up, because the project was developed earlier and you know the various ways to do it. In the familiar with the code and in the follow-up to some specific tasks, often found that some code is not conducive to reading comprehension and add new features, if only one or two lines of code, I directly changed, but some longer code, because the time relationship is expected to be delivered as soon as possible, the

The purpose of this title is simple, is to let us day after day in the code page of the Web refactoring workers, to regain the enthusiasm of the industry to face this we love; Examine the primary mistakes that are often overlooked by us in tedious work; take each page with enthusiasm and passion. It's basically what I want to say and need to reexamine, and I want to be a little guide to new people who are just starting out. In general, to receive a n

Labels: Software Design agility Next, let's take a look at what is in the System Reconstruction toolbox, that is, to see what methods are available for system reconstruction. System refactoring always adjusts our code at different levels, so the refactoring method is divided into multiple layers. In general, the reconstruction methods are divided into the following layers: reconstruction of methods, objects

Code refactoring has become a frequent issue. Since Martin Fowler's book refactoring, it has been around for ten years. Many programmers have become familiar with refactoring. However, whenever we face project pressure, we often leave the reconstruction behind and leave it out of the 9th cloud. There are enough reasons to explain: the function is not complete. Wh

When we begin to refactor the system, we do not start to modify the code, but first establish the test mechanism. No matter what the program, as long as we are modified, theoretically can introduce bugs, so we have to test. Since it's a test, you have to have a right or wrong standard of judgment. In previous tests, the criteria for their evaluation were whether they met business needs. As a result, testers often always hold the requirements document testing system. Unlike previous code modific

Whether in the iphone development or learning process will see some not very ideal code, it is undeniable that they are constantly "contributing" to this kind of code. In the face of some code "bad taste", refactoring is obviously an effective way to solve. The "reconstruction of the iphone" series wanted to summarize and supplement some of the refactoring that was going on in the development of the iphone,

LZ has been studying the Virtual Machine Source Code recently. Unfortunately, it's just a little bit of a clue. I can't share it with you. The huge Java Virtual Machine source code is really not something that can be done overnight, and LZ is excited. Aside from the relatively underlying Java Virtual Machine source code, LZ will discuss with you a few tips on code refactoring. This content is partly from books, it is partly from some practical experie
