                                                    Reflections.FieldRunner<A> runner)

Traverse through all fields with a certain annotation in a class and it super classes. Subclass first. If a field is re-declared in subclass, it will be skipped at the superclass.

forMethods

public static <A extends Annotation> void forMethods(Class<?> clazz,
                                                     Class<A> annotationClass,
                                                     Reflections.MethodRunner<A> runner)

Traverse through all methods with a certain annotation in a class, including ones inherited from its super class.
