Usage

From source file:com.xemantic.tadedon.guice.matcher.Annotations.java

/**
 * Finds if the {@code element} is annotated with the {@code annotationType}.
 * If the {@code element} is instance of {@link Class} or {@link Method},
 * the {@link AnnotationUtils#findAnnotation(Class, Class)} or
 * {@link AnnotationUtils#findAnnotation(Method, Class)} method will be used respectively. Thus it can
 * also find annotations from extended classes and implemented interfaces.
 *
 * @param element the element//from w w w  . ja va2  s  .  c  o m
 * @param annotationType the annotation type.
 * @return annotation instance or {@code null} if no annotation is found.
 * @throws IllegalArgumentException if the {@code element} is not instance of {@link Class} or {@link Method}.
