public class Util
extends java.lang.Object

Utility Class for globally useful methods

Field Summary

static boolean	allowNull Allow null fields during traversal
static java.lang.Class<?>[]	builtInArray
static java.util.HashSet<java.lang.Class<?>>	builtIns List of Primitive Classes
static boolean	skipPrivate Skip private fields during Traversal, this is set to true to be able to hide the library details, so we can use non Comparable types with an external Comparator
static boolean	warningOn Show Method selection Warnings
