What are the applicable scenarios of the factory method model

This article will explain in detail the applicable scenarios of the factory method model, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

The applicable scenarios of the factory method mode include: 1, when a class does not know the class of the object it must create; 2, when a class wants its subclass to specify the object it creates; 3, when the class delegates the responsibility of creating the object to one of several helper subclasses, and you want to localize information about which helper subclass is the agent.

Define an interface for creating objects, and let the subclass decide which class to instantiate. The factory method delays the instantiation of a class to its subclass

Applicability

When a class does not know the class of the object it must create

When a class wants its subclasses to specify the objects it creates

When a class delegates the responsibility of creating an object to one of several helper subclasses, and you want to localize which helper subclass is the agent

The applicable scenarios of the factory method model are shared here. I hope the above content can be of some help to you and can learn more knowledge. If you think the article is good, you can share it for more people to see.
