All Implemented Interfaces:

Sink, Source, EventDispatcher

Direct Known Subclasses:

StreamrProducer

public class I2PTunnelUDPServerBase
extends I2PTunnelTask
implements Source, Sink

Base client class that sets up an I2P Datagram server destination. The UDP side is not implemented here, as there are at least two possibilities: 1) UDP side is a "client" Example: Streamr Producer - configure an inbound port - External application receives no data - Extending class must have a constructor with a port argument 2) UDP side is a client/server Example: DNS - 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().

I2PTunnelUDPServerBase

public I2PTunnelUDPServerBase(boolean verify,
                              File privkey,
                              String privkeyname,
                              Logging l,

                              I2PTunnel tunnel)

Throws:

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

Method Detail

startRunning

public void startRunning()

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.

setReadTimeout

public void setReadTimeout(long ms)

Set the read idle timeout for newly-created connections (in milliseconds). After this time expires without data being reached from the I2P network, the connection itself will be closed.

getReadTimeout

public long getReadTimeout()

Get the read idle timeout for newly-created connections (in milliseconds).

Returns:

The read timeout used for connections

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 -

Throws:

RuntimeException - if session is closed
