In the process of software development, design patterns provide us with efficient solutions to various complex programming problems. As a structural design pattern, the Proxy Pattern is widely used in many practical development scenarios. This article will deeply analyze the concept of the Proxy Pattern, the difference from other similar patterns, the problems it solves, examples in practical applications, precautions, and implementation examples in Golang. What is the Proxy Pattern? The Proxy Pattern is a design pattern that allows an object to…

What is the Factory Method Pattern? The Factory Method Pattern is a creational design pattern that creates objects by defining an interface, but defers the specific implementation of the object to the subclass. This means that the Factory Method Pattern allows subclasses to decide which class to instantiate, making code expansion more flexible and easier to maintain. Compared with the Simple Factory Pattern, the Factory Method Pattern no longer relies on a single factory class, but implements object creation through an abstract factory interface. This…

Design Patterns is a summary of experience in software engineering, which provides solutions to common software design problems. Although design patterns themselves are not specific codes, they are some reusable design ideas and principles that can help developers write more flexible, maintainable and scalable codes. This blog will introduce the definition, meaning, classification and common examples of each type of design pattern in detail. By understanding these contents in depth, readers can understand how to use them in projects...
