Target (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

java.lang.annotation.Annotation
  java.lang.annotation.Target

public interface annotation Target
extends Annotation

Indicates the kinds of program element to which an annotation type is applicable. If a Target meta-annotation is not present on an annotation type declaration, the declared type may be used on any program element. If such a meta-annotation is present, the compiler will enforce the specified usage restriction. For example, this meta-annotation indicates that the declared type is itself a meta-annotation type. It can only be used on annotation type declarations:

    @Target(ElementType.ANNOTATION_TYPE)
    public @interface MetaAnnotationType {
        ... 
    }

This meta-annotation indicates that the declared type is intended solely for use as a member type in complex annotation type declarations. It cannot be used to annotate anything directly:

    @Target({}) 
    public @interface MemberType {
        ...
    }

It is a compile-time error for a single ElementType constant to appear more than once in a Target annotation. For example, the following meta-annotation is illegal:

    @Target({ElementType.FIELD, ElementType.METHOD, ElementType.FIELD})
    public @interface Bogus {
        ...
    }
