public class MethodIntrospector
extends java.lang.Object

An introspector for methods of various types. The introspector execution is parameterized by the hierarchy scope that is used to navigate the class and its super classes and implemented interfaces. The introspector execution is parameterized by the remove overrides boolean that tells to keep or not the overriden methods that are redefined in a class.
