Method Detail

createInitiatingSocket

public static UtpSocket createInitiatingSocket(DatagramChannel channel,
                                               short receiveConnectionId)

Creates a new UtpSocket and configures it to be the initiating side.

Parameters:

channel - The channel to write data on.

receiveConnectionId - The ID on which this socket will receive data.

Returns:

The newly created socket.

createRemoteConnecting

public static UtpSocket createRemoteConnecting(DatagramChannel channel,
                                               UtpPacket synPacket)

bind

public void bind(SocketAddress remoteAddress)

connect

public void connect(InetSocketAddress endpoint)
             throws IOException

Specified by:

connect in interface ISocket

Throws:

IOException

onReceivedPacket

public void onReceivedPacket(UtpPacket packet)

Updates the socket state based on the received packet.

Parameters:

packet - The received packet.

send

public void send(ByteBuffer data)

Submits data to be send.

Parameters:

data - The buffer to be send.

resend

public void resend(UtpPacket packet)

Submits a packet that has been previously sent but has not arrived on the remote.

Parameters:

packet - The packet to be resend.

acknowledgePacket

public void acknowledgePacket(Acknowledgement acknowledgement)

processSendQueue

public void processSendQueue()
                      throws IOException

Writes the UtpPacket onto the channel if the window allows for it. This will consume elements from resendQueue, sendQueue and packetAckHandler

Throws:

IOException

processTimeout

public void processTimeout()

Validates if the socket is in timeout state or not.

getPacketPayloadSize

public int getPacketPayloadSize()

Returns:

The amount of bytes the payload currently holds when transmitting a packet.

getInputStream

public InputStream getInputStream()
                           throws IOException

Specified by:

getInputStream in interface ISocket

Throws:

IOException
