public class IPwrap

extends java.lang.Object

This is a wrapper class for the Byte array IP value representation that allows IP addresses to be processed by the Ganymede namespace hash system.

Field Summary

(package private) java.lang.Byte[]

address

Constructor Summary

IPwrap(java.lang.Byte[] address)

Method Summary

boolean	equals(java.lang.Object value) Equality test.
int	hashCode() This method generates the hash key for this object for use in a Hashtable.
static short	s2u(byte b) This method maps a u2s-encoded signed byte value to an int value between 0 and 255 inclusive.
static byte	u2s(int x) This method maps an int value between 0 and 255 inclusive to a legal signed byte value.
