prototype design pattern

The Observer pattern is one of the software design Patterns . In this mode, a target object manages all the observer objects that are dependent on it and proactively notifies when its own state changes. This is usually done by calling the methods provided by each observer. This mode is often used for real-time event processing systems. ----WIKIPEDIAPersonal UnderstandingThe observer

This example describes the usage of JavaScript prototype patterns. Share to everyone for your reference. The specific analysis is as follows: After understanding the drawbacks of the factory model and the constructor pattern, we know why we need the prototype model.Definition of prototype mode I: Each function has a

PHP Design Pattern Observer Pattern example, PHP design pattern Observer First understand the concept of the Observer pattern: an object is made observable by adding a method that allows another object, the observer to register i

As a user experience research person, should not be unfamiliar with the prototype, whether it is to design physical devices, Web sites or applications, we will use the prototype. In the Internet field, designers often use the code of flash,html and so on to make prototypes, which makes the prototype more realistic and

Anyone involved in design patterns should have heard of the names of some patterns, including policy patterns and status patterns. they are the objects I want to discuss today. the reason for putting them together is that they have a certain relationship to help you really understand the design pattern. why is there no third one, because there are too many things

I. OverviewThe visitor pattern is a more complex, behavioral design pattern that contains the two main components of the visitor and the accessed element, which are often of different types, and that different visitors can perform different access operations on them. When using the visitor pattern, the elements that ar

In the previous article to introduce the JavaScript object-oriented Foundation, this article continues to delve into JavaScript object-oriented, JS syntax is very flexible, simple object creation there are several different methods. These are too flexible places are sometimes very confusing, then today we will comb the JS commonly used to create the object of several methods bar. Objective While using the object constructor, or the literal volume of objects, can be handy for creating an object

. There are some objects, such as threads (Thread) object or socket object, is not simple to copy or share. Whether using a shallow copy or a deep copy , as long as the indirect object is involved, the indirect object must be set to transient and not copied, or the program creates a fairly homogeneous object by itself. Right vote is used as a copy piece. Third, contrast through the above brief introduction to the shallow copy and deep copy, estimated in the brain already understood the approxim

The dynamic prototyping pattern is to encapsulate all the information into the constructor, and initialize the prototype in the constructors, maintaining the advantage of using constructors and prototypes at the same time. function Human (name, sex) { this.name = name; This.sex = sex; if (typeof This.say!= "function") { Human.prototype.say = function () { alert (this.name); } } var man =new Human ("Caesar

Mercedes-Benz is needed, but I don't care which workshop the car is produced. The difference between factory pattern and abstract factory pattern can be compared by BMW and Mercedes. In factory pattern, the user only needs to provide a product from the Mercedes-Benz workshop or the BMW workshop, that is, the product type has been specified by the user. In abstra
