public class WildcardDictionary
extends Dictionary
A dictionary with wildcard lookups.

The keys in this dictionary are wildcard patterns. When you do a get(), the string you pass in is matched against all the patterns, and the first match is returned.

The wildcard matcher is fairly simple, it implements * meaning any string, ? meaning any single character, and | separating multiple patterns. All other characters must match literally.
