Method Detail

setHostName

public void setHostName(java.lang.String hostname)

Description copied from class: KAPacketReceiver

explicitly sets the address of this packet receiver. This method allows users to set the host name or IP address that this receiver advertises as its externally-visible address. This might be necessary in the cases in which the Java VM can not reliably figure out such an address by itself.

Overrides:

setHostName in class KAPacketReceiver

receive

public int receive(byte[] buf)
            throws PacketReceiverException

Description copied from interface: PacketReceiver

receives a packet in the given buffer. This method must be reentrant. Siena clients and servers must be able to use several threads to receive packets from the same receiver.

Specified by:

receive in interface PacketReceiver

Overrides:

receive in class KAPacketReceiver

Returns:

the number of bytes read into the buffer. The return value must not be negative. On error conditions, this method must throw an exception.

Throws:

PacketReceiverException - in case an error occurrs while reading.

address

public byte[] address()

external address of this packet receiver. Uses the following schema syntax:
schema:host:port

Specified by:

address in interface PacketReceiver

guessMyIPAddress

protected static java.net.InetAddress guessMyIPAddress()
                                                throws java.net.UnknownHostException

Throws:

java.net.UnknownHostException

guessMyIPAddress

protected static java.net.InetAddress guessMyIPAddress(java.net.ServerSocket s)
                                                throws java.net.UnknownHostException

Throws:

java.net.UnknownHostException

guessMyIPAddress

protected static java.net.InetAddress guessMyIPAddress(java.net.DatagramSocket s)
                                                throws java.net.UnknownHostException

Throws:

java.net.UnknownHostException
