This paper describes the design idea of reusable and extensible MIME coding class, and compares the difference between template method and strategy mode by the way.
I. Background knowledge
MIME is an Internet protocol, all called "Multipurpose Internet Mail Extensions", and the Chinese name is "Multipurpose Internet Mail Extension." In fact, its application is not limited to sending and receiving Internet
Design Pattern-Template MethodDescription:Define the skeleton of an algorithm in a method. Delay some steps to the subclass. The template method allows the subclass to redefine some steps in the algorithm without changing the algorithm structure.HOOK: defines an empty method or default method, and provides the user subclass to overwrite and implement its own judg

模板方法这个名字看着很陌生,其实在游戏中大量地使用了模板方法,因为游戏中存在玩家、NPC和静态物体等不同的对象,使用多态特性能很好地进行区分。 模板方法的定义是:模板方法模式:在一个方法中定义一个算法的骨架,而将一些步骤延迟到子类中。模板方法使得子类可以在不改变算法结构的情况下,重新定义算法中的某些步骤。举个最简单的玩家和NPC死亡时的逻辑:流程图如下:The code is as follows//MVC.cpp: Defines the entry point of the console application. //#include "stdafx.h"#include #include #include using namespace STD;classobject{ Public: Object (): M_dead (0) { }voidSetdead () {cout"========================="cout"========================="Virtual voidBeforedead () {}Virtual voi

In the field of cyberground, the position of each toy is fixed, and the ring is carefully designed so it can only encircle one toy at a time.

Korean website design has always been well-known. Although this style has been replaced by the simplified and practical Web 2.0, many details are worth learning. I hope you can learn more from the template instead of simply using the template.

and can is accessed outside of the project.Using Access control we can only expose the API we want the other objects to use, and hide the properties or methods we do NT want to, which can leads to loosely coupling.For example, we can use computed properties to being the API for other objects, and we can use the Set{}or get{}to interact W ith private value and add more spedified logic.Sorry guys i ' m using a Chinese blog website, so I had no idea if there was a blog I can use in 中文版, please lea

The template schema prepares an abstract class, implements some of the logic in concrete ways and concrete constructs, and then declares some abstract methods to force subclasses to implement the remaining logic. Different subclasses can implement these abstract methods in different ways, thus having different implementations of the remaining logic. First, a top-level logical framework is developed, and the details of the logic are left to the specifi
The Silent EeerOriginal address: http://www.cnblogs.com/hebaichuanyeah/p/6092152.htmlOnce written in Qt, there is a need to add a custom event to all of the program's interfaces. The event is triggered by a thread.It is really troublesome to add a single event binding to each interface object.So I wrote an event's parent interface, binding the thread to an event filter function in an event, and then deciding whether to trigger an event in the event filter, and then invoking an event response fun
When designing my own template analysis class, the first question I encountered was how to design my own tag syntax. After referring to and comparing many label representations, I decided to use the label representations of class. Net controls. Because I think this is the only way. net programmers can quickly get familiar with these things, rather. net programmers will not be too difficult to learn, because
