This article will explain in detail what structural design patterns there are, and the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Structural design patterns include composite pattern (Composite), appearance pattern (Facade), proxy pattern (Proxy), adapter pattern (Adapter), decoration pattern (Decrator), bridge pattern (Bridge), and shared element pattern (Flyweight).

In design patterns, structural types are:

1. Composite, combination pattern: combine objects into a tree structure to represent the relationship between parts as a whole. Composite enables users to use single objects and combined objects consistently.

2. Facade, appearance mode: provides a consistent interface for a set of interfaces in the subsystem. Fa?ade provides a high-level interface that makes the subsystem easier to use.

3. Proxy, proxy mode: provides a proxy for other objects to control access to this object

4. Adapter, adapter pattern: convert one kind of interface into another interface that the customer wants. Adapter mode makes those classes that can't work together because the interface is not compatible can work together.

5. Decrator, Decoration pattern: dynamically add some additional responsibilities to an object. In terms of added functionality, Decorator mode is more flexible than generating subclasses.

6. Bridge, bridge mode: separate the abstract part from its implementation part, so that they can change independently.

7. Flyweight, enjoy meta-mode

About what structural design patterns are shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
