This article focuses on "what are the structural models of web". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what are the structural models of web?"

Adapter, Decorator and Proxy

These three patterns are very similar. The following are compared in terms of interface, function, and implementation work:

Adapters and adapters use different interfaces and basically achieve the same function. The main work of the adapter is interface conversion.

The decorator and the decorative object use the same interface, adding new functions to the decorative object. The job of the decorator is to implement these new functions.

Proxies and proxy objects have the same interface and basically achieve the same function. The agent's job is to help absorb some additional requirements, such as saving memory, increasing access control, breaking software / hardware communication barriers, and so on.

Composite

The combination pattern provides a standard way to implement a tree structure, and users can use the same point of view to deal with nodes on the tree data structure.

Bridge

The bridging mode separates the interface class from the implementation class, so that the inheritance structure of m × n is transformed into the inheritance structure of m × n.

Flyweight

The sharing meta-pattern provides a standard means of sharing data among users.

Facade

The appearance pattern provides the subsystem with interface classes that are functional enough to meet the requirements and are more convenient to use.
