object oriented analysis and design book

For the design of object-oriented software systems, improving system reusability while supporting maintainability is a crucial issue, how to Improve the maintainability and reusability of a software system at the same time is one of the core issues that need to be addressed in object-

In the previous article, we talked about the design patterns. Next, let's talk about some of the principles we often follow in object-oriented design. These principles are the result of numerous previous experiences. Only by following these principles can you involve excellent code. Today we will talk about seven princ

, the constructor pattern is used to define instance properties (each instance itself is unique, not shared), whereas the prototype pattern is used to define methods and shared properties.6.2.5 Dynamic Prototyping ModeAll information is encapsulated in the constructor, and the prototype is initialized in the constructor function.function Person (name, age, Job) { this. Name = name; this. Age = Age ; this. Job = job; if (typeofthis. Sayname! = "Functin") {// in the case that the Sayna

by the program, the value of the inside does not know when will be overwritten If you pass a class, struct, and so on, the parameters and return values are passed through some space in memory.The reference is converted into a pointer operation.Constructor: The same as the class name, no return value, implementation of the class member initialization. It is best to initialize the initial value list, and if the function body is initialized, the data member has completed the default initialization

At first, I thought it was too dull. In the eighth chapter, the author's analysis of the object-oriented problem, I follow the design and development of the book, understand some of the concepts previously just seen in the book.Make some notes for yourself:1. The virtual bas

rules of the class.Properties and Methods Casting from the Mold (object), there are a lot of parameters (length, width, height, etc.), can complete different operations (cooking, load-bearing, protection of internal parts, etc.). The argument here is the object's "property", and the complete operation is the object's "method". A property is a variable that represents the characteristics of an object, suc

1. To learn the design mode, first understand what the design mode is: 1. What is the design model? The design pattern describes a general solution to a type of common problems in the software design process. 2. What is an object-

reasons such as the need to modify the original code of the software, may introduce errors in the old code, or we will have to refactor the entire functionality, and the original code needs to be tested again. This has a special impact on our entire system, which also fully shows the coupling of the system if too high, will greatly increase the later expansion, maintenance. In order to solve this problem, people have summed up the principle of opening and closing. The fundamental solution to th
