/** * Gets annotations that are associated with the specified element. If there * are no annotations associated with the element, the return value is an * empty map. The difference between this method and * {@link AnnotatedElement#getAnnotationsByType(Class)} is that this method * works on annotation classes that are annotated with the {@link Keyable} * annotation in order to determine the key of each annotation. For this to * work, the annotated class must defined a key element as defined in the * {@link Keyable} annotation of the same return type as specified in * <code>keyClass</code>. If its argument is a repeatable annotation type * (JLS 9.6), this method, attempts to find one or more annotations of that * type by "looking through" a container annotation. The caller of this method * is free to modify the returned map; it will have no effect on the maps * returned to other callers./* ww w . j a va 2 s .co m*/ * <p> * This method will look for both the specified annotation and if the * annotation is annotated with {@link Repeatable}, it will also look for this * containing annotation which must have a <code>value()</code> * element with an array type of the specified annotation. The resulting * array will always start with the annotation itself if found followed by * all of those provided by the containing annotation. * * @author paouelle * * @param <K> the type of the keys to find * @param <T> the type of the annotation to query for and return if present * * @param keyClass the class of the keys to find and return * @param annotationClass the type of annotations to retrieve * @param annotatedElement the element from which to retrieve the annotations * @return a non-<code>null</code> ordered map of annotations associated with the * given element properly keyed as defined in each annotation (may be * empty if none found) * @throws NullPointerException if <code>annotatedElement</code>, * <code>annotationClass</code> or <code>keyClass</code> is * <code>null</code> * @throws IllegalArgumentException if <code>annotationClass</code> is not * annotated with {@link Keyable} or if the containing annotation * doesn't define a <code>value()</code> element returning an array * of type <code>annotationClass</code> or if <code>annotationClass</code> * doesn't define an element named as specified in its {@link Keyable} * annotation that returns a value of the same class as <code>keyClass</code> * or again if a duplicated keyed annotation is found */ @SuppressWarnings("unchecked") public static <K, T extends Annotation> Map<K, T> getAnnotationsByType(Class<K> keyClass, Class<T> annotationClass, AnnotatedElement annotatedElement) { org.apache.commons.lang3.Validate.notNull(annotationClass, "invalid null annotation class"); org.apache.commons.lang3.Validate.notNull(annotatedElement, "invalid null annotation element"); org.apache.commons.lang3.Validate.notNull(keyClass, "invalid null key class"); final Keyable k = annotationClass.getAnnotation(Keyable.class); org.apache.commons.lang3.Validate.isTrue(k != null, "annotation @%s not annotated with @Keyable", annotationClass.getName()); final Method km; try { km = annotationClass.getMethod(k.value()); } catch (NoSuchMethodException e) { throw new IllegalArgumentException( "annotation key element @" + annotationClass.getName() + "." + k.value() + "() not found", e); } org.apache.commons.lang3.Validate.isTrue(keyClass.isAssignableFrom(km.getReturnType()), "annotation key element @%s.%s() doesn't return class: %s", annotationClass.getName(), k.value(), keyClass.getName()); final T[] as = annotatedElement.getAnnotationsByType(annotationClass); if (as.length == 0) { return Collections.emptyMap(); } final Map<K, T> map = new LinkedHashMap<>(as.length); for (T a : as) { final K ak; try { ak = (K) km.invoke(a); } catch (IllegalAccessException e) { // not expected throw new IllegalStateException(e); } catch (InvocationTargetException e) { final Throwable t = e.getTargetException(); if (t instanceof Error) { throw (Error) t; } else if (t instanceof RuntimeException) { throw (RuntimeException) t; } else { // not expected throw new IllegalStateException(e); } } org.apache.commons.lang3.Validate.isTrue(map.put(ak, a) == null, "duplicate key '%s' found in annotation @%s", ak, annotationClass.getName()); } return map; }
