public class GHashtable

extends java.util.Hashtable

GHashtable is a Hashtable subclass that can map uppercase/lowercase keys of the same string to identity. It does this by basically mapping all strings to the lowercase version internally. The case sensitivity of the hashtable is specified at hash creation time, and may not change thereafter.

This hashtable also has special support for handling arrays of Bytes as keys in the hash, using the IPwrap class for I.P. address representation.
