## Annotation Type Target

-     @Documented
       @Retention(value=RUNTIME)
       @Target(value=ANNOTATION_TYPE)
      public @interface Target

  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 {
              ...
          }
