java.lang.annotation
  Provides library support for the Java programming language
 annotation facility.
  
    
Annotations
    
  
  
    
      
        | Documented | 
        
          If the annotation @Documented is present on the declaration
 of an annotation interface A, then any @A annotation 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.Repeatable is
 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.

        | 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.
