Software 152 Liu AnminAOP is the continuation of OOP and is the abbreviation for Aspect oriented programming, meaning aspect-oriented programming. AOP is actually a continuation of the GOF design pattern, and the design pattern pursues the decoupling between the caller and the callee, and AOP can be said to be an implementation of this goal.The implementation of AOP technology, mainly divided into two major

1 AOPOverviewAOP (aspect-oriented programming, aspect-oriented programming ): is a new methodology for traditional OOP ( Object-oriented programming, Object-oriented programming ) complements. The main object of the AOP programming operation is the tangent plane (aspect), while the facets are modular crosscutting concerns .When you apply AOP programming, you st

Part 4 and 5th of this series discuss how to use Javassist to make local changes to a binary class. This time you will learn to use the framework in a more powerful way to take advantage of Javassist's support for finding all specific methods or fields in bytecode. For the Javassist feature, this feature is at least as important as its ability to specify bytecode in a similar way to source code. Support for the Select substitution operation also helps make javasssist a great tool for adding

1. What I know about AOPAt first glance, there is a lot of terminology, and there is a name for the wind, for the aspect programming, is a useful complement of OOP and so on. Let you at a loss, thought: Not many people and I said that AOP is more difficult. When I look inside, I can only find out: He is a simple and unpretentious application on Java basis, including the IOC (see the Spring IOC (dependency injection, inversion of control) conceptual un

PHP aspect-oriented programming component. We use the MVC framework, such as CI, YII, and cakePHP. one of the reasons is that the code can be easily maintained. However, when the business logic is constantly complicated, the more we call the methods in the model in the controller, the more we use the MVC framework, such as CI, YII, and cakePHP. one of the reasons is that the code can be easily maintained. However, when the business logic is constantl

Detailed description of the Python decorator mode and Aspect-Oriented Programming This article mainly introduces the Python decorator mode and Specific Aspect-oriented programming. In summary, the function of the decorator is to add additional functions for existing objects, this article details all aspects of the decorative device model, and then introduces the knowledge of cross-section programming. For m

@aspect of Spring AOP Transferred from: http://blog.csdn.net/tanghw/article/details/3862987Starting with Spring 2.0, you can implement AOP using schema-and @aspectj-based approaches, a simple example of how to implement AOP in spring in a @aspectj way. Since @aspect is annotation-based, it is required to support more than 5.0 versions of the JDK for annotations.Environmental requirements: 1. Web Applicatio

Aspect can clear code pollution? Logging with the Aspectwerkz framework is the first step Introduction: Aspect-oriented programming (aspect-oriented PROGRAMMING,AOP) allows code to be kept clean by separating functionality that works within the application scope rather than in a class or package. Logging is a common example of this functionality. Can AOP help wi

At present, many TV stations use 16:9 HD camera shooting, but many local stations broadcast signal is 720x576 PAL format, need to do the next transformation of the collected material.The lower converter will provide a variety of down-conversion methods, before I mention the letter of the Edge way, this time I focus on cut cut edge way, this should also be the majority of TV workers in the post-editing will be used.1920x1080 aspect ratio is 16:9, do th

Share to everyone for your reference. Specific as follows: /*** Create a thumbnail image from $inputFileName no taller or wider than* $maxSize. Returns the new image resource or false on error.* author:mthorn.net*/function thumbnail ($inputFileName, $

1. Why is cross-section-oriented programming? Aspect-oriented programming (AOP is the abbreviation of Aspect Oriented Program)We know that object-oriented features inheritance, polymorphism, and encapsulation. Encapsulation requires that functions be distributed to different objects, which is often called Responsibility Assignment in software design. In fact, let different classes design different methods

an object while the system is running .。this is achieved through DI (Dependency injection, Dependency injection) .。 For example, object A needs to manipulate the database, and we've always had toHave written code to get a Connection object, with spring we just need to tell spring,a need a connection, as for this connection how to construct, when constructs, a does not need to know. When the system is running, spring will be in the appropriateTime to make a connection, and then, like an injectio

Gary Pollice, Professor of Practice, Worcester Institute of Technology May 15, 2006 A review of the concept of AOP If you are unfamiliar with AOP, there are a lot of introductory articles about it, including the articles I published in February 2004. 2 A lot, maybe not all, introduction to AOP use the log as an example to illustrate aspects of the concept. (logs are something that many people understand, and it's a good example of how AOP can be used.) ) concern is crosscutting. That is to say,

and elegant. In future maintenance, because the business logic code is separated from the common code, and the common code is stored in a centralized manner, maintenance becomes simple and easy. The Aspect-Oriented Programming AOP technology was born to solve this problem. The Aspect-oriented programming is a horizontal aspect, as shown in 6-5, which represents

Using polymorphism, we can implement AOP (Aspect programming) and ashxaop in general processing programs (ashx ). This article is a process of thinking about various solutions for code optimization (improved AOP aspect programming for login verification) for projects at work. Project Background: A simple B/S questionnaire system built by ashx + nvelocity needs to optimize the logon verification process (it

This article mainly introduces the round of Javascriptaop (cross-section programming). If you need it, you can refer to Aop, which is also called cross-section programming. the "notification" is the specific implementation of the cross-section, it can be divided into before (pre-notification), after (post-notification), and around (surround notification). those who have used spring must be very familiar with it, but in js, AOP is a technical point that has been seriously ignored. However, aop ca
