Description

The list of methods to do Reflection Annotation Find are organized into topic(s).

Method

AfindAnnotationInAnyParameter(Method method, Class annotationClass)
Tries to extract the first occurrence an annotation of a certain class inside a method's parameters. 
for (Parameter parameter : method.getParameters()) {
    if (parameter.isAnnotationPresent(annotationClass)) {
        return parameter.getAnnotation(annotationClass);
return null;
AfindAnnotationInMethodOrInItsAnnotations(Method method, Class annotationClass)
Tries to extract an annotation of a certain class directly annotated on to the method or any of its annotations. 
if (method.isAnnotationPresent(annotationClass)) {
    return method.getAnnotation(annotationClass);
for (Annotation annotation : method.getAnnotations()) {
    Class<? extends Annotation> annotationType = annotation.annotationType();
    if (annotationType.isAnnotationPresent(annotationClass)) {
        return annotationType.getAnnotation(annotationClass);
return null;
SetfindAnnotationMethods(String fullClassName, Class anno)
find Annotation Methods 
Set<Method> methodSet = new HashSet<Method>();
Class<?> clz = Class.forName(fullClassName);
Method[] methods = clz.getDeclaredMethods();
for (Method method : methods) {
    if (method.getModifiers() != Modifier.PUBLIC) {
        continue;
    Annotation annotation = method.getAnnotation(anno);
...
LinkedHashMap,T>findAnnotationsMap(Class a, Class c)
Same as #findAnnotations(Class,Class) except returns the annotations as a map with the keys being the class on which the annotation was found. 
LinkedHashMap<Class<?>, T> m = new LinkedHashMap<Class<?>, T>();
findAnnotationsMap(a, c, m);
return m;
AnnotationfindAnnotationSuperClasses(Class annotationClass, Class c)
find Annotation Super Classes 
while (c != null) {
    Annotation result = c.getAnnotation(annotationClass);
    if (result != null)
        return result;
    else
        c = c.getSuperclass();
return null;
...
AnnotationfindAnnotationWithMetaAnnotation(Class clazz, Class metaAnnotationType)
find Annotation With Meta Annotation 
Annotation annotation = getAnnotationWithMetaAnnotation(clazz, metaAnnotationType);
if (annotation != null) {
    return annotation;
for (Class<?> ifc : clazz.getInterfaces()) {
    annotation = findAnnotationWithMetaAnnotation(ifc, metaAnnotationType);
    if (annotation != null) {
        return annotation;
