Java Reflection - Get All Methods In Hierarchy

Quick static utility to obtain all declared methods in the class hierarchy.

/**
 * Gets an array of all methods in a class hierarchy walking up to parent classes
 * @param objectClass the class
 * @return the methods array
 */
 public static Method[] getAllMethodsInHierarchy(Class<?> objectClass) {
 Set<Method> allMethods = new HashSet<Method>();
 Method[] declaredMethods = objectClass.getDeclaredMethods();
 Method[] methods = objectClass.getMethods();
 if (objectClass.getSuperclass() != null) {
 Class<?> superClass = objectClass.getSuperclass();
 Method[] superClassMethods = getAllMethodsInHierarchy(superClass);
 allMethods.addAll(Arrays.asList(superClassMethods));
 }
 allMethods.addAll(Arrays.asList(declaredMethods));
 allMethods.addAll(Arrays.asList(methods));
 return allMethods.toArray(new Method[allMethods.size()]);
 }
