Java in a Nutshell, 5th Edition [Electronic resources] نسخه متنی

This
interface is implemented by the
classes representing program elements that can be annotated in
Java
5.0: java.lang.Class,
java.lang.Package, Method,
Constructor, and Field. The
methods of this interface allow you to test for the presence of a
specific annotation, query an annotation object of a specific type,
or query all annotations present on an annotated element.
getdeclaredAnnotations(
) differs from getAnnotations(
) in that it does not include inherited annotations. (See
the java.lang.annotation.Inherited
meta-annotation.) If no annotations are present,
getAnnotations( ) and
geTDeclaredAnnotations( ) return an array of
length zero rather than null. It is safe to modify
the arrays returned by these methods.

See also the getParameterAnnotations( ) methods of
Method and Constructor, which
provide access to annotations on method parameters.
