The nesting kind of a type element.
Type elements come in four varieties:
top-level, member, local, and anonymous.
Nesting kind is a non-standard term used here to denote this
classification.
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(); }

values
Returns an array containing the constants of this enum class, in the order they are declared.- Returns:
- an array containing the constants of this enum class, in the order they are declared
-
valueOf
Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum class has no constant with the specified nameNullPointerException
- if the argument is null
-
isNested
public boolean isNested()Does this constant correspond to a nested type element? A nested type element is any that is not top-level. More specifically, an inner type element is any nested type element that is not static.- Returns:
- whether or not the constant is nested
