  Provides library support for the Java programming language
 annotation facility.
  
    
Annotations
    
  
  
    
      
        | Documented | If the annotation @Documentedis present on the declaration
 of an annotation interface A, then any@Aannotation on
 an element is considered part of the element's public contract. | 
      
    
      
        | Inherited | Indicates that an annotation interface is automatically inherited. | 
      
    
      
        | Native | Indicates that a field defining a constant value may be referenced
 from native code. | 
      
    
      
        | Repeatable | The annotation interface java.lang.annotation.Repeatableis
 used to indicate that the annotation interface whose declaration it
 (meta-)annotates is repeatable. | 
      
    
      
        | Retention | Indicates how long annotations with the annotated interface are to
 be retained. | 
      
    
      
        | Target | Indicates the contexts in which an annotation interface is applicable. | 
      
    
  
  
  
    Interfaces
    
  
  
    
      
        | Annotation | The common interface extended by all annotation interfaces. | 
      
    
  
  
  
  
    Enums
    
  
  
    
      
        | ElementType | The constants of this enumerated class provide a simple classification of the
 syntactic locations where annotations may appear in a Java program. | 
      
    
      
        | RetentionPolicy | Annotation retention policy. | 
      
    
  
  
  
    Exceptions
    
  
  
    
      
        | AnnotationTypeMismatchException | Thrown to indicate that a program has attempted to access an element of
 an annotation whose type has changed after the annotation was compiled
 (or serialized). | 
      
    
      
        | IncompleteAnnotationException | Thrown to indicate that a program has attempted to access an element of
 an annotation interface that was added to the annotation interface definition
 after the annotation was compiled (or serialized). | 
      
    
  
  
  
    Errors
    
  
  
    
      
        | AnnotationFormatError | Thrown when the annotation parser attempts to read an annotation
 from a class file and determines that the annotation is malformed. |
