This collection of texts originates from a book titled " 一本书看透股权架构 " by  李利威 , which translates to " A Book to See Through Equity Structures ". Published in 2019, it focuses on the intricacies of company equity, covering various aspects from the perspectives of  legal regulations, taxation, finance, and management . The material explores different types of  companie...

Also known as: Cache  Flyweight  is a structural design pattern that lets you fit more objects into the available amount of RAM by sharing common parts of state between multiple objects instead of keeping all of the data in each object.

Facade is a structural design pattern that provides a simplified interface to a library, a framework, or any other complex set of classes.

Decorator  is a structural design pattern that lets you attach new behaviors to objects by placing these objects inside special wrapper objects that contain the behaviors.

Composite  is a structural design pattern that lets you compose objects into tree structures and then work with these structures as if they were individual objects.

Bridge  is a structural design pattern that lets you split a large class or a set of closely related classes into two separate hierarchies—abstraction and implementation—which can be developed independently of each other.

The adapter, also known as a  wrapper, is a structural design pattern that allows objects with incompatible interfaces to collaborate.

DI frameworks , conversely, address these issues by enabling  mock object injection  for testing,  dynamic configuration ,  loose coupling  through interfaces, and simplified  multithreading and resource management . This ultimately results in more  flexible, testable, and maintainable  systems.

Factory Method  is a creational design pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.

Prototype is a creational design pattern that lets you copy existing objects without making your code dependent on their classes.

Builder is a creational design pattern that lets you construct complex objects step by step. The pattern allows you to produce different types and representations of an object using the same construction code.

Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes. https://www.youtube.com/watch?v=xbjAsdAK4xQ https://refactoring.guru/design-patterns/abstract-factory

Factory Method  is a creational design pattern that provides an interface for creating objects in a superclass but allows subclasses to alter the type of objects that will be created.

Summary This article mainly introduces software design patterns. It explains the concept of design patterns as typical solutions to common software design problems, rather than specific code, and distinguishes them from algorithms. The article elaborates on the components of design patterns, such as intent, motivation, structure, and code examples, and provides a catalog of various design patterns...
