Field Detail

mainServer

protected Core mainServer

Handle to the Core server.

socket

protected java.net.Socket socket

Internal data holders set up by the connectToClient function.

initPacket

protected Packet initPacket

dataDecoder

protected AmberInputStream dataDecoder

type

protected int type

loggingFile

protected Log loggingFile

Primary logging object.

encoderBytes

protected java.io.ByteArrayOutputStream encoderBytes

The data encoding data stream that is used by all components to send information. THIS MUST BE USED FOR ENCODING INFORMATION TO THE CLIENT!! Owing to the way Java works it is not meaningful to have a corresponding input object statically created.

dataEncoder

protected AmberOutputStream dataEncoder

BaseHandler

public BaseHandler()

Method Detail

setCore

public void setCore(Core core)

This sets the parent Core object.

Specified by:

setCore in interface HandlerInterface

Parameters:

core - Core system.

setLogger

public void setLogger(Log logger)

This sets the primary logging object.

Specified by:

setLogger in interface HandlerInterface

Parameters:

logger - Log primary logger.

sendPacket

public void sendPacket(java.net.Socket socket,
                       Packet packet)

Sends the specified packet to the defined socket connection.

Parameters:

socket - Socket to send the packet to.

packet - Packet containing the packet to send.

connectToClient

public void connectToClient(java.net.Socket socket,
                            Packet initPacket,
                            AmberInputStream dataDecoder,
                            int type)
                     throws java.io.IOException

This function handles the connection requirements for the specified incoming connection. In this case the connection is from a Browser based system.

Specified by:

connectToClient in interface HandlerInterface

Parameters:

socket - Socket of the incoming connection.

initPacket - The Packet which is first sent by the page when the connection is opened.

dataDecoder - AmberInputStream with the packet parameters.

type - The type of connection that is attempting to match the packet. This matches the constants in ListenerThread.

Throws:

java.io.IOException - containing decoding errors.
