Yii2的深入学习--继承关系，yii2深入学习--
想要了解 Yii2 的话，一定要对 Yii2 中向相关类的继承关系有所了解。由于暂时读的代码有限，下面的图中只列出了部分继承关系，之后回跟着源码阅读的越来越多而增加
由上图可以看到 Yii2 中大多数类都继承自 yii\base\Object，实现了属性的功能。
yii\base\Component yii\base\Event 和 yii\base\Behavior 都继承了 yii\base\Object，yii\base\Component 是一个实现了属性/事件和行为功能的基础类，yii\base\Event 是所有事件的基础类，yii\base\Behavior 是所有行为的基础类。
Model/View 和 Controller 都从 yii\base\Component 继承而来。
今天比较累，偷个懒，少写一点，就这些了O(∩_∩)O
对 Yii2 源码有兴趣的同学可以关注项目 yii2-2.0.3-annotated，现在在上面已经添加了不少关于 Yii2 源码的注释，之后还会继续添加～
有兴趣的同学也可以参与进来，提交 Yii2 源码的注释。

Detailed explanation of C++ function inheritance: How to use 'base class pointer' and 'derived class pointer' in inheritance?
May 01, 2024 pm 10:27 PM
In function inheritance, use "base class pointer" and "derived class pointer" to understand the inheritance mechanism: when the base class pointer points to the derived class object, upward transformation is performed and only the base class members are accessed. When a derived class pointer points to a base class object, a downward cast is performed (unsafe) and must be used with caution.
Let's learn how to input the root number in Word together
Mar 19, 2024 pm 08:52 PM
When editing text content in Word, you sometimes need to enter formula symbols. Some guys don’t know how to input the root number in Word, so Xiaomian asked me to share with my friends a tutorial on how to input the root number in Word. Hope it helps my friends. First, open the Word software on your computer, then open the file you want to edit, and move the cursor to the location where you need to insert the root sign, refer to the picture example below. 2. Select [Insert], and then select [Formula] in the symbol. As shown in the red circle in the picture below: 3. Then select [Insert New Formula] below. As shown in the red circle in the picture below: 4. Select [Radical Formula], and then select the appropriate root sign. As shown in the red circle in the picture below:
Detailed explanation of C++ function inheritance: How to debug errors in inheritance?
May 02, 2024 am 09:54 AM
Inheritance error debugging tips: Ensure correct inheritance relationships. Use the debugger to step through the code and examine variable values. Make sure to use the virtual modifier correctly. Examine the inheritance diamond problem caused by hidden inheritance. Check for unimplemented pure virtual functions in abstract classes.
Detailed explanation of C++ function inheritance: How to understand the 'is-a' and 'has-a' relationship in inheritance?
May 02, 2024 am 08:18 AM
Detailed explanation of C++ function inheritance: Master the relationship between "is-a" and "has-a" What is function inheritance? Function inheritance is a technique in C++ that associates methods defined in a derived class with methods defined in a base class. It allows derived classes to access and override methods of the base class, thereby extending the functionality of the base class. "is-a" and "has-a" relationships In function inheritance, the "is-a" relationship means that the derived class is a subtype of the base class, that is, the derived class "inherits" the characteristics and behavior of the base class. The "has-a" relationship means that the derived class contains a reference or pointer to the base class object, that is, the derived class "owns" the base class object. SyntaxThe following is the syntax for how to implement function inheritance: classDerivedClass:pu
Learn the main function in Go language from scratch
Mar 27, 2024 pm 05:03 PM
Title: Learn the main function in Go language from scratch. As a simple and efficient programming language, Go language is favored by developers. In the Go language, the main function is an entry function, and every Go program must contain the main function as the entry point of the program. This article will introduce how to learn the main function in Go language from scratch and provide specific code examples. 1. First, we need to install the Go language development environment. You can go to the official website (https://golang.org
How do inheritance and polymorphism affect class coupling in C++?
Jun 05, 2024 pm 02:33 PM
Inheritance and polymorphism affect the coupling of classes: Inheritance increases coupling because the derived class depends on the base class. Polymorphism reduces coupling because objects can respond to messages in a consistent manner through virtual functions and base class pointers. Best practices include using inheritance sparingly, defining public interfaces, avoiding adding data members to base classes, and decoupling classes through dependency injection. A practical example showing how to use polymorphism and dependency injection to reduce coupling in a bank account application.
Java Interfaces and Abstract Classes: The Road to Programming Heaven
Mar 04, 2024 am 09:13 AM
Interface: An implementationless contract interface defines a set of method signatures in Java but does not provide any concrete implementation. It acts as a contract that forces classes that implement the interface to implement its specified methods. The methods in the interface are abstract methods and have no method body. Code example: publicinterfaceAnimal{voideat();voidsleep();} Abstract class: Partially implemented blueprint An abstract class is a parent class that provides a partial implementation that can be inherited by its subclasses. Unlike interfaces, abstract classes can contain concrete implementations and abstract methods. Abstract methods are declared with the abstract keyword and must be overridden by subclasses. Code example: publicabstractcla
C++ Function Inheritance Explained: How to Design a Good Base and Derived Class Inheritance Hierarchy?
May 03, 2024 am 11:06 AM
Function inheritance enables derived classes to inherit methods from base classes, enabling code reuse and polymorphism. Designing a good inheritance hierarchy following the single responsibility, open-closed, and Rees substitution principles can avoid code coupling and diamond problems.
