public XBeeTrafficController()

Method Detail

getIEEE802154Message

public IEEE802154Message getIEEE802154Message(int length)

Get a message of a specific length for filling in.

This is a default, null implementation, which must be overridden in an adapter-specific subclass.

Overrides:

getIEEE802154Message in class IEEE802154TrafficController

Parameters:

length - length for new message

Returns:

null since this method should be over-ridden

newReply

protected AbstractMRReply newReply()

Get a message of zero length.

Specified by:

newReply in class AbstractMRTrafficController

connectPort

public void connectPort(AbstractPortController p)

Make connection to an existing PortController object.

Overrides:

connectPort in class AbstractMRTrafficController

Parameters:

p - the PortController

forwardToPort

protected void forwardToPort(AbstractMRMessage m,
                             AbstractMRListener reply)

Actually transmit the next message to the port.

Overrides:

forwardToPort in class IEEE802154TrafficController

Parameters:

m - the message to send

reply - the Listener sending the message, often provided as 'this'

See Also:

AbstractMRTrafficController.sendMessage(AbstractMRMessage, AbstractMRListener)

pollMessage

protected AbstractMRMessage pollMessage()

Invoked if it's appropriate to do low-priority polling of the command station, this should return the next message to send, or null if the TC should just sleep.

Overrides:

pollMessage in class IEEE802154TrafficController

Returns:

Formatted poll message

pollReplyHandler

protected AbstractMRListener pollReplyHandler()

Overrides:

pollReplyHandler in class IEEE802154TrafficController

enterProgMode

protected AbstractMRMessage enterProgMode()

Description copied from class: AbstractMRTrafficController

Set the system to programming mode.

Overrides:

enterProgMode in class IEEE802154TrafficController

Returns:

any message that needs to be returned to the Command Station to change modes. If no message is needed, returns null.

See Also:

AbstractMRTrafficController.enterNormalMode()

enterNormalMode

protected AbstractMRMessage enterNormalMode()

Description copied from class: AbstractMRTrafficController

Sets the system to normal mode during programming while in IDLESTATE. If AbstractMRTrafficController.programmerIdle() returns true, enterNormalMode() is called after a timeout.

Overrides:

enterNormalMode in class IEEE802154TrafficController

Returns:

any message that needs to be returned to the Command Station to change modes. If no message is needed, returns null.

See Also:

AbstractMRTrafficController.enterProgMode()

receiveLoop

public void receiveLoop()

Description copied from class: AbstractMRTrafficController

Handle incoming characters. This is a permanent loop, looking for input messages in character form on the stream connected to the PortController via AbstractMRTrafficController.connectPort(AbstractPortController).

Each turn of the loop is the receipt of a single message.

Overrides:

receiveLoop in class AbstractMRTrafficController

registerNode

public void registerNode(AbstractNode node)

Register a node.

Overrides:

registerNode in class AbstractMRNodeTrafficController

Parameters:

node - the node object to register

deleteNode

public void deleteNode(XBeeNode node)

packetReceived

public void packetReceived(com.digi.xbee.api.packet.XBeePacket response)

Specified by:
