Enum Class TypeAnnotation.TargetType

java.lang.Object

java.lang.Enum<TypeAnnotation.TargetType^PREVIEW>

java.lang.classfile.TypeAnnotation.TargetType

All Implemented Interfaces:

Serializable, Comparable<TypeAnnotation.TargetTypePREVIEW>, Constable

Enclosing interface:

TypeAnnotationPREVIEW

public static enum TypeAnnotation.TargetType
extends Enum<TypeAnnotation.TargetTypePREVIEW>

TargetType is a preview API of the Java platform.

Programs can only use TargetType when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

The kind of target on which the annotation appears, as defined in JVMS 4.7.20.1.
