Interface OutgoingPacketMangler

All Known Implementing Classes:

FNPPacketMangler

public interface OutgoingPacketMangler

Low-level interface for sending packets. A UDP-based transport will have to implement both this and IncomingPacketFilter, usually on the same class.

Method Summary

Modifier and Type	Method and Description
boolean	allowConnection(PeerNode node, FreenetInetAddress addr) Is there any reason not to allow this connection? E.g.
boolean	alwaysAllowLocalAddresses() Always allow local addresses?
byte[]	getCompressedNoderef() Get our compressed noderef
AddressTracker.Status	getConnectivityStatus() Port forwarding status.
Peer[]	getPrimaryIPAddress() Get our addresses, as peers.
SocketHandler	getSocketHandler() The SocketHandler we are connected to.
boolean	isDisconnected(PeerContext context) Is a peer disconnected?
void	sendHandshake(PeerNode pn, boolean notRegistered) Send a handshake, if possible, to the node.
void	setPortForwardingBroken() If the lower level code detects the port forwarding is broken, it will call this method.
int[]	supportedNegTypes(boolean forPublic) List of supported negotiation types in preference order (best last)

Method Detail

sendHandshake

void sendHandshake(PeerNode pn,
                   boolean notRegistered)

Send a handshake, if possible, to the node.

Parameters:

pn -

isDisconnected

boolean isDisconnected(PeerContext context)

Is a peer disconnected?

supportedNegTypes

int[] supportedNegTypes(boolean forPublic)

List of supported negotiation types in preference order (best last)

getSocketHandler

SocketHandler getSocketHandler()

The SocketHandler we are connected to.

getPrimaryIPAddress

Peer[] getPrimaryIPAddress()

Get our addresses, as peers.

getCompressedNoderef

byte[] getCompressedNoderef()

Get our compressed noderef

alwaysAllowLocalAddresses

boolean alwaysAllowLocalAddresses()

Always allow local addresses?

getConnectivityStatus

AddressTracker.Status getConnectivityStatus()

Port forwarding status.

Returns:

A status code from AddressTracker. FIXME make this more generic when we need to.

allowConnection

boolean allowConnection(PeerNode node,
                        FreenetInetAddress addr)

Is there any reason not to allow this connection? E.g. limits on the number of nodes on a specific IP address?

setPortForwardingBroken

void setPortForwardingBroken()

If the lower level code detects the port forwarding is broken, it will call this method.
