Package net.i2p.router.transport

Class GeoIP

java.lang.Object
net.i2p.router.transport.GeoIP
public class GeoIP extends Object
Manage geoip lookup in a file with the Tor geoip format. The lookup is expensive, so a lookup is queued with add(). The actual lookup of multiple IPs is fired with lookup(). To get a country for an IP, use get() which returns a lower-case, generally two-letter country code or null. Everything here uses longs, since Java is signed-only, the file is sorted by unsigned, and we don't store the table in memory (unlike in Blocklist.java, where it's in-memory so we want to be space-efficient)
