public class DefaultClassDepthMap
extends ClassDepthMap

A DefaultClassDepthMap computes class depth simply and efficiently. It uses a ClassHierarchy object to enable it to implement the maxDepth() method. It also caches the depths it computes to avoid having to traverse the entire class inheritance tree repeatedly.
