Target in Java

java.lang.annotation.Target

Indicates the contexts in which an annotation type is applicable.

If an @Target meta-annotation is not present on an annotation type T, then an annotation of type T may be written as a modifier for any declaration except a type parameter declaration.

Declaration

@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.ANNOTATION_TYPE)
public @interface Target {

    ElementType[] value();
}


Methods

ElementType[] java.lang.annotation.Target.value()

Returns an array of the kinds of elements an annotation type can be applied to.

Returns: an array of the kinds of elements to an annotation type can be applied to.


Some other classes/interfaces of java.lang.annotation

Native: Indicates that a field defining a constant value may be referenced from native code.

InheritedIndicates that an annotation type is automatically inherited.

IncompleteAnnotationExceptionThrown to indicate that a program has attempted to access an element of an annotation type that was added to the annotation type definition after the annotation was compiled (or serialized). 

AnnotationFormatErrorThrown when the annotation parser attempts to read an annotation from a class file and determines that the annotation is malformed.

ElementTypeThe constants of this enumerated type provide a simple classification of the syntactic locations where annotations may appear in a Java program.

DocumentedIf the annotation @Documented is present on the declaration of an annotation type A, then any @A annotation on an element is considered part of the element's public contract.

AnnotationTypeMismatchExceptionThrown to indicate that a program has attempted to access an element of an annotation whose type has changed after the annotation was compiled.

AnnotationThe common interface is extended by all annotation types.

RepeatableThe annotation type is java.lang.annotation.Repeatable is used to indicate that the annotation type whose declaration it(meta-)annotates is repeatable.

RetentionIndicates how long annotations with the annotated type are to be retained. If no Retention annotation is present on an annotation-type declaration, the retention policy defaults to RetentionPolicy.CLASS.

RetentionPolicyAnnotation retention policy. The constants of this enumerated type describe the various policies for retaining annotations.

TargetIndicates the contexts in which an annotation type is applicable.
