package java.lang.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:
* <pre>
* &#064;Target(ElementType.ANNOTATION_TYPE)
* public &#064;interface MetaAnnotationType {
* ...
* }
* </pre>
* 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:
* <pre>
* &#064;Target({})
* public &#064;interface MemberType {
* ...
* }
* </pre>
* 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:
* <pre>
* &#064;Target({ElementType.FIELD, ElementType.METHOD, ElementType.FIELD})
* public &#064;interface Bogus {
* ...
* }
* </pre>
