Apache Yetus Audience Annotations framework introduction and usage method analysis

Apache Yetus Audience Annotations (later referred to as Annotations) is a framework for adding target reader information to document and code.By using Annotations, developers can write in the code of the code to remember which code blocks or document paragraphs are written for specific reader groups, so as to provide better document navigation and code reuse. Annotations can be used to describe various target readers, such as beginners, senior developers, document editors, testers, etc.Developers can define their target readers according to their own needs and apply them to code and document comments. By adding the annotation of a target reader to the code, the code can be easier to understand and maintain.Developers can check the annotations in the code to understand which reader group is written to which reader groups, so as to better understand the design ideas and uses of the code. A common case is to use Annotations to specify different target readers in the comment.For example, the "@Beginner" annotation can be added for the friendly code segment of beginners, and the "@Advanced" annotation can be added for the code segment of senior developers.Developers can then generate documents or code packages of specific readers by writing custom plug -in or tools according to their needs. Below is an example of Java code using Annotations: public class MyClass { /** * This method performs a basic addition operation. * * @param num1 the first number * @param num2 the second number * @return the sum of the two numbers */ @Beginner public int add(int num1, int num2) { return num1 + num2; } /** * This method performs a more complex calculation. * * @param num1 the first number * @param num2 the second number * @return the result of the calculation */ @Advanced public int calculate(int num1, int num2) { return num1 * num2; } } In the above example, we use two custom Annotations: "@Beginner" and "@Advanced".The ADD method is marked as "@Beginner" annotation, indicating that this is a code for beginners.The Calculating method is marked as "@Advanced" annotation, indicating that this is a code for senior developers. Through Annotations, it is easier for developers to understand the purpose of these two methods and generate corresponding documents or code packs as needed. In summary, Annotations is a framework for adding target reader information to code and documentation.It can use custom annotations in code annotations to make the code easier to understand and maintain.Through customized tools or plugins, documents or code packages of specific readers can be generated according to these annotations.
