Method Detail

forwardMessage

protected void forwardMessage(AbstractMRListener client,
                              AbstractMRMessage m)

Forward a CanMessage to all registered CanInterface listeners. Implement this to forward a specific message type to a protocol-specific listener interface. This puts the casting into the concrete class.

Specified by:

forwardMessage in class AbstractMRTrafficController

Parameters:

client - abstract listener.

m - message to forward.

forwardReply

protected void forwardReply(AbstractMRListener client,
                            AbstractMRReply r)

Forward a CanReply to all registered CanInterface listeners.

Specified by:

forwardReply in class AbstractMRTrafficController

isBootMode

public boolean isBootMode()

sendCanMessage

public void sendCanMessage(CanMessage m,
                           CanListener reply)

Forward a preformatted message to the actual interface. Send a message through the interface.

Parameters:

m - Message to be sent.

reply - Listener to be notified of reply.

sendCanReply

public void sendCanReply(CanReply r,
                         CanListener reply)

Forward a preformatted reply to the actual interface. Send a reply through the interface.

Parameters:

r - Reply to be sent.

reply - Listener to be notified of reply.

addTrailerToOutput

protected void addTrailerToOutput(byte[] msg,
                                  int offset,
                                  AbstractMRMessage m)

Add trailer to the outgoing byte stream.

Overrides:

addTrailerToOutput in class AbstractMRTrafficController

Parameters:

msg - The output byte stream

offset - the first byte not yet used

m - output message to extend

lengthOfByteStream

protected int lengthOfByteStream(AbstractMRMessage m)

Determine how many bytes the entire message will take, including space for header and trailer

Overrides:

lengthOfByteStream in class AbstractMRTrafficController

Parameters:

m - The message to be sent

Returns:

Number of bytes

newMessage

protected AbstractMRMessage newMessage()

Description copied from class: AbstractCanTrafficController

Get the correct concrete class for the hardware connection message

Specified by:

newMessage in class AbstractCanTrafficController

Returns:

new blank message

decodeFromHardware

public CanReply decodeFromHardware(AbstractMRReply m)

Make a CanReply from a system-specific reply. loop back returns null.

Specified by:

decodeFromHardware in class AbstractCanTrafficController

encodeForHardware

public AbstractMRMessage encodeForHardware(CanMessage m)

Encode a CanMessage for the hardware. loop back returns null.

Specified by:

encodeForHardware in class AbstractCanTrafficController

newReply

protected AbstractMRReply newReply()

Specified by:

newReply in class AbstractMRTrafficController

endOfMessage

protected boolean endOfMessage(AbstractMRReply r)

Dummy; loopback doesn't parse serial messages.

Specified by:

endOfMessage in class AbstractMRTrafficController
