All Implemented Interfaces:

Serializable, Cloneable, Map, NavigableMap, SortedMap

public class LengthTreeMap
extends TreeMap

A tree map used for mapping variable names to values. To allow a distinction between two names where one is the starting part of another variable this map is ordered for decreasing variable length. An example would be two variables apple and appletree. In this map, iterating over the keys will retrive appletree prior to apple making the correct treatment of such ambigouse cases easy.
