Class InetAddressComparator

java.lang.Object

freenet.support.io.InetAddressComparator

All Implemented Interfaces:

java.util.Comparator<java.net.InetAddress>

public class InetAddressComparator
extends java.lang.Object
implements java.util.Comparator<java.net.InetAddress>

Fast non-lexical Comparator for IP addresses for cases where an attacker might forge IP addresses to try to exhaust a hashtable, so we need to use a TreeMap, but we don't actually care whether similar IPs are close together.
