Class PeerID

java.lang.Object
  org.klomp.snark.PeerID

All Implemented Interfaces:

Comparable

public class PeerID
extends Object
implements Comparable

Store the address information about a peer. Prior to 0.8.1, an instantiation required a peer ID, and full Destination address. Starting with 0.8.1, to support compact tracker responses, a PeerID can be instantiated with a Destination Hash alone. The full destination lookup is deferred until getAddress() is called, and the PeerID is not required. Equality is now determined solely by the dest hash.

Constructor Summary

PeerID(BDecoder be)
Creates a PeerID from a BDecoder.

PeerID(byte[] id, Destination address)

PeerID(byte[] dest_hash, I2PSnarkUtil util)
Creates a PeerID from a destHash

PeerID(Map m)
Creates a PeerID from a Map containing BEncoded peer id, ip and port.

Method Summary

int	compareTo(Object o) Deprecated. unused? and will NPE now that address can be null?
boolean	equals(Object o) Two PeerIDs are equal when they have the same dest hash
Destination	getAddress() Get the destination.
byte[]	getDestHash()
byte[]	getID()
int	getPort()
int	hashCode() The hash code of a PeerID is the hashcode of the desthash
static String	idencode(byte[] bs) Encode an id as a hex encoded string and remove leading zeros.
boolean	sameID(PeerID pid) Returns true if and only if this peerID and the given peerID have the same destination hash
void	setID(byte[] xid) for connecting out to peer based on desthash @since 0.8.1
String	toString() Returns the String "id@address" where id is the base64 encoded id and address is the base64 dest (was the base64 hash of the dest) which should match what the bytemonsoon tracker reports on its web pages.

Constructor Detail

PeerID

public PeerID(byte[] id,
              Destination address)

PeerID

public PeerID(BDecoder be)
       throws IOException

Creates a PeerID from a BDecoder.

Throws:

IOException

PeerID

public PeerID(Map m)
       throws InvalidBEncodingException,
              UnknownHostException

Creates a PeerID from a Map containing BEncoded peer id, ip and port.

Throws:

InvalidBEncodingException

UnknownHostException

PeerID

public PeerID(byte[] dest_hash,
              I2PSnarkUtil util)
       throws InvalidBEncodingException

Creates a PeerID from a destHash

Parameters:

util - for eventual destination lookup

Throws:

InvalidBEncodingException

Since:

0.8.1

Method Detail

getID

public byte[] getID()

setID

public void setID(byte[] xid)

for connecting out to peer based on desthash @since 0.8.1

getAddress

public Destination getAddress()

Get the destination. If this PeerId was instantiated with a destHash, and we have not yet done so, lookup the full destination, which may take up to 10 seconds.

Returns:

Dest or null if unknown

getPort

public int getPort()

getDestHash

public byte[] getDestHash()

Since:

0.8.1

hashCode

public int hashCode()

The hash code of a PeerID is the hashcode of the desthash

Overrides:

hashCode in class Object

sameID

public boolean sameID(PeerID pid)

Returns true if and only if this peerID and the given peerID have the same destination hash

equals

public boolean equals(Object o)

Two PeerIDs are equal when they have the same dest hash

Overrides:

equals in class Object

compareTo

public int compareTo(Object o)

Deprecated. unused? and will NPE now that address can be null?

Compares port, address and id.

Specified by:

compareTo in interface Comparable

toString

public String toString()

Returns the String "id@address" where id is the base64 encoded id and address is the base64 dest (was the base64 hash of the dest) which should match what the bytemonsoon tracker reports on its web pages.

Overrides:

toString in class Object

idencode

public static String idencode(byte[] bs)

Encode an id as a hex encoded string and remove leading zeros.
