findAnnotation

public static <A extends java.lang.annotation.Annotation> java.util.Optional<A> findAnnotation(java.lang.reflect.AnnotatedElement element,
                                                                                               java.lang.Class<A> annotationType)

Find the first annotation of annotationType that is either present or meta-present on the supplied element.

findRepeatableAnnotations

public static <A extends java.lang.annotation.Annotation> java.util.List<A> findRepeatableAnnotations(java.lang.reflect.AnnotatedElement element,
                                                                                                      java.lang.Class<A> annotationType)

Find all repeatable annotations of annotationType that are either present, indirectly present, or meta-present on the supplied AnnotatedElement.

This method extends the functionality of AnnotatedElement.getAnnotationsByType(Class) with additional support for meta-annotations.

Returns:

the list of all such annotations found; never null
