The synthetic multiplexing principle, also known as the combinatorial/aggregation multiplexing principle (composition/aggregate reuse Principle, CARP), is defined as follows: Synthetic multiplexing principles (Composite reuse Principle, CRP): Try to use object combinations instead of inheritance to achieve reuse. The principle of synthetic multiplexing is to use some existing objects in a new

Object-oriented callback functions The design method of process language C has corresponding implementation methods in object-oriented language C + +. The object-oriented

concerned about: Publicclass User { public bool IsValid () { if (username.length > 0 isemailvalid ()) { //.... } //... } BOOL Isemailvalid () { return email. Contains ("@") (email. EndsWith (". com") | | Email. EndsWith (". Biz")); } public string EmailAddress () { return string. Format ("\" {0}\ " } private String Convert () { if (email. IndexOf (' # ')! =-1) { return email. Replace (' # ', ' @ '); } } } I think maybe we're missing an email concept, so we can encapsulate these methods and

phase, the analyst only gives some textual description according to the user's request, in the design phase, the designer will make the screen visualization of these general descriptions, and may also consult the relevant technical experts; Before programming, the user's visual prototype should be further improved by graphic artists and behavioral artists to achieve The "user-friendly" definition standard; The implementation phase, the program develo

direct interaction, if necessary, can use a third party to forward the call. Our unique unique knowledge is the introduction of a façade object that provides a single, simple barrier between subsystems. Usually the three-layer or N-layer architecture of enterprise software, the separation between layer and layer is actually the embodiment of the appearance pattern.Enjoy meta mode, outraged, yell, let me try: objects make memory consumption too much.

The authors of this book describe each design pattern by using a class diagram (the UML class diagrams, the basics of which are described in addition to the object-oriented language applet + character dialogue interpretation knowledge points. This article is the introduction of "Big talk design mode" used in the

Labels: Object-oriented Design Principles After the previous in-depth explanation, we have basically made it clear about the solid principle. However, if you want to skillfully apply the solid principle, it is not enough to know what the solid is, we also need to know when and when the solid principle is applied (when or where ). Fortunately, the five independen

One of the most powerful features of object-oriented programming is its dynamic nature. Dynamic code has a whole new meaning as the world continues to emerge with more available features, hybrid structures, and standards for sustainable development. Whether it's a new file storage standard or streaming media standard, or a social web site or some new thing on the Internet Pioneer API, Web programming is alw

Common Features of Excellent Software: low coupling and High Cohesion Polymorphism: static polymorphism (function polymorphism, function overload), dynamic polymorphism (virtual function) Basic object-oriented principles Principle of opening/closing: a module should be open to expansion and should be closed for modification. Principle of full replacement: The derived class should be able to completely repla

before we start the Android software app, we need to make a preliminary understanding of object-oriented design principles and design patterns. Talent in the future combat process, less detours. Make our software development career feel happy and relaxed. Okay, nonsense, let's talk about the software development

Since the publication of "subvert traditional-object-oriented design ideas (collation)", many of my friends and comments have been posted, either good or bad. Of course, there are also many friends in Article In the comments, I posted my own opinions. Here I will explain some typical comments. From wanghualiangComment Code highlighting produced by Ac

First, we need to know what the mode is: In short: while people constantly discover problems and find solutions to problems in their own environments, discovering different problems actually involves a common nature. These essence is what we call models. Therefore, the model is representative. In the Object-Oriented field, the earliest modeling method research was published in 1995 by Gang of Four (gof, Eri

The author's classic discussion of object-oriented analysis and design:OOP: Object-oriented programming is an implementation method that is organized into a collaborative collection of objects, each representing an instance of a class that is a member of a class hierarchy that is joined by an inheritance relationship.

http://blog.csdn.net/lovelion/article/details/7537584In order to satisfy the principle of opening and closing, abstract design is needed for the system, and abstraction is the key to open and close principle. In programming languages such as Java, C #, you can define a relatively stable abstraction layer for the system, and move the different implementation behaviors to the specific implementation layer. In many o
