org.bitcoinj.core.PeerAddress

public class PeerAddress
extends ChildMessage

A PeerAddress holds an IP address and port number representing the network location of a peer in the Bitcoin P2P network. It exists primarily for serialization purposes.

This class abuses the protocol version contained in its serializer. It can only contain 0 (format within VersionMessage), 1 (AddressV1Message) or 2 (AddressV2Message).

Instances of this class are not safe for use by multiple threads.

Constructor Details

PeerAddress

public PeerAddress(NetworkParameters params,
 byte[] payload,
 int offset,
 Message parent,
 MessageSerializer serializer)
            throws ProtocolException

Construct a peer address from a serialized payload.

Parameters:

params - NetworkParameters object.

payload - Bitcoin protocol formatted byte array containing message content.

offset - The location of the first payload byte within the array.

serializer - the serializer to use for this message.

Throws:

ProtocolException

PeerAddress

public PeerAddress(NetworkParameters params,
 InetAddress addr,
 int port,
 BigInteger services,
 MessageSerializer serializer)

Construct a peer address from a memorized or hardcoded address.

PeerAddress

public PeerAddress(NetworkParameters params,
 InetAddress addr,
 int port,
 BigInteger services)

Constructs a peer address from the given IP address, port and services. Version number is default for the given parameters.

PeerAddress

public PeerAddress(NetworkParameters params,
 InetAddress addr,
 int port)

Constructs a peer address from the given IP address and port. Version number is default for the given parameters.

PeerAddress

public PeerAddress(NetworkParameters params,
 InetAddress addr)

Constructs a peer address from the given IP address. Port and version number are default for the given parameters.

PeerAddress

public PeerAddress(NetworkParameters params,
 InetSocketAddress addr)

Constructs a peer address from an InetSocketAddress. An InetSocketAddress can take in as parameters an InetAddress or a String hostname. If you want to connect to a .onion, set the hostname to the .onion address.

PeerAddress

public PeerAddress(NetworkParameters params,
 String hostname,
 int port)

Constructs a peer address from a stringified hostname+port. Use this if you want to connect to a Tor .onion address.

Method Details

localhost

public static PeerAddress localhost(NetworkParameters params)
