public enum NestingKind extends Enum<NestingKind>
Note that it is possible additional nesting kinds will be added in future versions of the platform.
Example: The classes below are annotated with their nesting kind.
import java.lang.annotation.*; import static java.lang.annotation.RetentionPolicy.*; import javax.lang.model.element.*; import static javax.lang.model.element.NestingKind.*; @Nesting(TOP_LEVEL) public class NestingExamples { @Nesting(MEMBER) static class MemberClass1{} @Nesting(MEMBER) class MemberClass2{} public static void main(String... argv) { @Nesting(LOCAL) class LocalClass{}; Class<?>[] classes = { NestingExamples.class, MemberClass1.class, MemberClass2.class, LocalClass.class }; for(Class<?> clazz : classes) { System.out.format("%s is %s%n", clazz.getName(), clazz.getAnnotation(Nesting.class).value()); } } } @Retention(RUNTIME) @interface Nesting { NestingKind value(); }
