Application instance of Apache Yetus Audience Annotations in the Java Library

Apache Yetus Audience Annotations is an annotation in the Apache Yetus project, which is used to identify the type of audience.There are many applications in the Java library. The following will introduce some common example examples. 1. The type of audience of the identifier: @InterfaceAudience.Public public class StringUtils { // omit other code } In this example, the StringUtils class is marked as a public interface audience.This means that this category is public and can be used for anyone. 2. The audience type of identification method: public class MathUtils { // omit other code @InterfaceAudience.Private public static int add(int a, int b) { return a + b; } } In this example, the ADD method is marked as the type of private interface audience.This means that this method can only be accessed and called inside the Mathutils class, and should not be made public. 3. The type of audience of the identification field: public class Configuration { @InterfaceAudience.Public public static final int MAX_CONNECTIONS = 10; // omit other code } In this example, the Max_Connections field is marked as a public interface audience type.This means that the field is visible to the outside and can be accessed and used in other categories. Summarize: Apache Yetus Audience Annotations is an annotation in the Apache Yetus project, which is used to identify the type of audience.By using these annotations, you can clearly express the visibility and scope of use of the code to provide better code maintenance and management.It is widely used in the Java library and can be understood and used by the above examples.
