Class SOCKSUDPPort

java.lang.Object

net.i2p.i2ptunnel.socks.SOCKSUDPPort

All Implemented Interfaces:

Sink, Source

public class SOCKSUDPPort
extends Object
implements Source, Sink

Implements a UDP port and Socks encapsulation / decapsulation. This is for a single port. If there is demuxing for multiple ports, it happens outside of here. TX: UDPSource -> SOCKSUDPUnwrapper -> (I2PSink in SOCKSUDPTunnel) RX: UDPSink <- SOCKSUDPWrapper ( <- MultiSink <- I2PSource in SOCKSUDPTunnel) The Unwrapper passes headers to the Wrapper through a cache. MultiSink routes packets based on toPort.

                 int fromPort,
                 int toPort,
                 byte[] data)

May throw RuntimeException from underlying sink

Specified by:

send in interface Sink

Parameters:

from - will be passed along

fromPort - will be passed along

RuntimeException

setSink

public void setSink(Sink sink)

Sets the sink for incoming UDP datagrams from I2P.

Specified by:

setSink in interface Source
