| /** |
| * 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> |
| * @Target(ElementType.ANNOTATION_TYPE) |
| * public @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> |
| * @Target({}) |
| * public @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> |
| * @Target({ElementType.FIELD, ElementType.METHOD, ElementType.FIELD}) |
| * public @interface Bogus { |
| * ... |
| * } |
| * </pre> |
