Adapter mode Adapter): Converts an interface of a class to another interface that the customer wants. The A d a p t e r mode makes those classes that cannot work together due to interface incompatibility work together.
Applicable scenarios:
1. Existing class interfaces do not meet our needs;
2. Create a reusable class so that the class can work collaboratively with other unrelated classes or unforeseen clas

Overview
In software systems, due to changes in the application environment, we often need to put "some existing objects" in the new environment for application, however, the interfaces required by the new environment are not met by these existing objects. So how should we deal with this "Migration change "? How can we make good use of the existing object and meet the interfaces required by the new application environment? This is the Adapter mode des
Problem Introduction: for example, if there are A-type and B-type nuts, you can directly use A-type screws produced by A-type nuts on a-type nuts, you can also directly use B-type screws produced according to B-type Nut standards on B-type nuts. However, because a-type nut and B-type nut have different standards, you cannot directly use B-type screws on A-type nut, and vice versa. How can we achieve this goal?
You can solve this problem by using an adapter
Adapter mode (Adapter pattern)——. NET design Pattern series eightTERRYLEE,2006 year FebruaryOverviewIn the software system, because of the change of the application environment, it is often necessary to put "some existing objects" in the new environment, but the interfaces required by the new environment are not satisfied by these existing objects. So how do you deal with this "migration change"? How can yo
I. Introduction
In the actual development process, due to the changes in the application environment, such as the changes in the use language), we need to implement that there is no existing object in the new environment to meet, however, such existing objects exist in other environments. So what if we call "existing objects" in the new environment? The solution to this problem is the adapter mode we will introduce in this article --In this way, exist

The adapter mode converts an interface of a class into another interface that the client expects, so that the two classes that the original interface does not match and cannot work together can work together.

Adapter Mode definition: Jiuge two incompatible classes together, in a structured pattern, with two identities (adaptee) and adaptor (adapters). Why use adapter mode we often encounter the need to combine two classes that are not related to each other, the first solution is to modify the interfaces of the respective classes, but if we do not have the source code, or we do not want to modify the respective i
The adapter mode converts an interface of a class into another interface that the client expects, so that the two classes that the original interface does not match and cannot work together can work together.

Structural patterns (structural pattern) describe how a class or object can be combined to form a larger structure. The structure pattern describes two different things: a class and an instance of a class. According to this point, the structure pattern can be divided into the structure pattern of the class and the structure pattern of the object.
