Opening and closing principles Definition: A software entity such as classes, modules, and functions should be open to extensions and closed for modification. The source of the problem: in the software lifecycle, because of changes, upgrades, and maintenance, and other reasons for the software to modify the original code, may introduce errors in the old code, may also cause us to have to refactor the entire function, and the need for the original cod

Why design patterns? Let's take a look at the six principles and use the design pattern principles. Introduction　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 I don't like reading books very much, because I forgot to read ten lines of books, so I read the left teacher and copied it to improve my memory.

package, it will affect all classes in the package, but it will not affect other packages. Package coupling principle No-ring dependency principle (Acyclic Dependencies Principle, ADP) The package dependency does not allow loops. Stable-Dependencies Principle, SDP) Dependency in a stable direction Stable-abstractions principle (SAP) The abstraction level of the package should be consistent with its stability. Old ti

weigh repeatedly, not only to make the structure clear, but also to achieve high cohesion and low coupling.---> Dimitri Law requires decoupling between classes, but the decoupling is limited, the principle is only for reference, if it violates this principle, the project may not fail, which requires you to use the principle of repeated measures, do not follow is not correct, strict implementation is "too bad."Iv.: Central idea(1) in a scene, the A,b,c class. Complete a goal. A relies on b,b to

Single Responsibility Principle, abbreviated as SRP.Definition: There should never is more than one reason for a class-to-change.There should be and only one cause for class changes.Division of duties? A single definition and level?should be based on actual business conditions. Focus on the point of change.In practice, classes are difficult to do with a single function, but the interface should be as single as possible.Design pattern six Principles/In

This article was compiled from 〈a Matter of principle〉, author of Facebook product design director Julie Zhuo.Julie stressed in the article, designers make every design decision behind, should have to have this, it is best to have to stand the test of the principle of support, and these principles can be scaled, so that other members of the team can understand, d

I. Design Principles1. Dependency inversion principle (DIP) High-level modules (stability) should not depend on low-level modules (changes), both of which should depend on abstraction.Abstract (stable) should not depend on implementation details (changes), and implementation details should depend on abstraction. 2. Open and closed principle (OCP) Class modules should be extensible, but cannot be modified; open to extensions and closed to changes

closed principle is vague. It only describes how the objects in the software are opened for extensions, but not modified or disabled. The principle of opening and closing is an abstract summary of the first five principles. The first five principles are specific implementations of the principle. Therefore, if the principle of opening and closing is used, it is actually a bit false because it does not have
