Interface AnnotatedElement
java.lang.reflect.AnnotatedElement
Direct Known Subclasses:
public interface AnnotatedElement
Represents an annotated element of the program currently running in this
VM. This interface allows annotations to be read reflectively. All
annotations returned by methods in this interface are immutable and
serializable. It is permissible for the caller to modify the
arrays returned by accessors for array-valued enum members; it will
have no affect on the arrays returned to other callers.
Since:If an annotation returned by a method in this interface contains (directly or indirectly) a -valued member referring to a class that is not accessible in this VM, attempting to read the class by calling the relevant Class-returning method on the returned annotation will result in a .
Similarly, attempting to read an enum-valued member will result in a if the enum constant in the annotation is no longer present in the enum type.
Finally, Attempting to read a member whose definition has evolved incompatibly will result in a or an .

Methods
| getAnnotation (Class annotationType) | ||
Returns this element's annotation for the specified type if such an annotation is present, else null. |
| getAnnotations () | ||
Returns all annotations present on this element. (Returns an array of length zero if this element has no annotations.) The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers. |
| getDeclaredAnnotations () | ||
Returns all annotations that are directly present on this element. Unlike the other methods in this interface, this method ignores inherited annotations. (Returns an array of length zero if no annotations are directly present on this element.) The caller of this method is free to mo ... more > |
boolean | isAnnotationPresent (Class annotationType) | |
Returns true if an annotation for the specified type is present on this element, else false. This method is designed primarily for convenient access to marker annotations. |
