SOCKSUDPTunnel, StreamrConsumer

public abstract class I2PTunnelUDPClientBase
extends I2PTunnelTask
implements Source, Sink

Base client class that sets up an I2P Datagram client destination. The UDP side is not implemented here, as there are at least two possibilities: 1) UDP side is a "server" Example: Streamr Consumer - Configure a destination host and port - External application sends no data - Extending class must have a constructor with host and port arguments 2) UDP side is a client/server Example: SOCKS UDP (DNS requests?) - configure an inbound port and a destination host and port - External application sends and receives data - Extending class must have a constructor with host and 2 port arguments So the implementing class must create a UDPSource and/or UDPSink, and must call setSink().

I2PTunnelUDPClientBase

public I2PTunnelUDPClientBase(String destination,
                              Logging l,
                              EventDispatcher notifyThis,
                              I2PTunnel tunnel)
                       throws IllegalArgumentException

Throws:

IllegalArgumentException - if the I2CP configuration is b0rked so badly that we cant create a socketManager

Method Detail

startRunning

public void startRunning()

Actually start working on outgoing connections. Classes should override to start UDP side as well. Not specified in I2PTunnelTask but used in both I2PTunnelClientBase and I2PTunnelServer so let's implement it here too.

close

public boolean close(boolean forced)

I2PTunnelTask Methods Classes should override to close UDP side as well

Specified by:

close in class I2PTunnelTask

Returns:

success

setSink

public void setSink(Sink s)

Source Methods Sets the receiver of the UDP datagrams from I2P Subclass must call this after constructor and before start()

Specified by:

setSink in interface Source

start

public void start()

start the source

Specified by:

start in interface Source

send

public void send(Destination to,
                 byte[] data)

Sink Methods

Specified by:

send in interface Sink

Parameters:

to - - ignored if configured for a single destination (we use the dest specified in the constructor)

Throws:

RuntimeException - if session is closed
