Constructor Detail

Controller

public Controller(Transport transport,
                  int priority)

Parameters:

transport - The transport (Transport) parameter.

priority - The priority (int) parameter.

Method Detail

enqueueRestartTransport

protected void enqueueRestartTransport()

Enqueue restart transport.

enqueueRestartTransportNoOutput

protected void enqueueRestartTransportNoOutput()

Enqueue restart transport no output.

errorOccurred

public void errorOccurred(java.lang.Object source,
                          java.lang.Object timestamp,
                          java.lang.Object data)

Description copied from interface: ErrorListener

The errorOccurred method is called when an error has occurred. Since other notifications are blocked until this method returns, implementors of this method should:

• Not cause the device or transport to be blocked (eg calling read on a measuremnt).
• Handle this call quickly and return.

The source object that detected the error. The time at which the error was detected. Contains any data about the error.

Specified by:

errorOccurred in interface ErrorListener

Parameters:

source - The source (Object) parameter.

timestamp - The timestamp (Object) parameter.

data - The data (Object) parameter.

errorOccurredSend

public void errorOccurredSend(java.lang.Object source,
                              java.lang.Object timestamp,
                              java.lang.Object data)

Parameters:

source - The source (Object) parameter.

timestamp - The timestamp (Object) parameter.

data - The data (Object) parameter.

getQueueSizeProblem

public int getQueueSizeProblem()

Gets the queue size problem (int) value.

Returns:

The queue size problem (int) value.

See Also:

setQueueSizeProblem(int)

messageReceived

public void messageReceived(TransportService transportService,
                            java.lang.Object timestamp,
                            MessageService message)

Description copied from interface: MessageListener

This API will be called each time the TransportService receives a valid message. Since other notifications are blocked until this method returns, implementors of this method should:

• Not cause the device or transport to be blocked (eg calling read on a measuremnt).
• Handle this call quickly and return.

The transport that received the message. The timestamp when the message was detected. The message received.

Specified by:

messageReceived in interface MessageListener

Parameters:

transportService - The transport service (TransportService) parameter.

timestamp - The timestamp (Object) parameter.

message - The message (MessageService) parameter.

restartTransport

public void restartTransport()

Restart transport.

Specified by:

restartTransport in interface ControllerService

See Also:

enqueueRestartTransport()

run

public void run()

Perform the run action method.

Specified by:

run in interface java.lang.Runnable

See Also:

Runnable.run()

setQueueSizeProblem

public void setQueueSizeProblem(int queueSizeProblem)

Parameters:

queueSizeProblem - The queue size problem (int) parameter.

See Also:

getQueueSizeProblem()

start

public void start()

Start.

Specified by:

start in interface ControllerService

See Also:

start(boolean)

start

public void start(boolean output)

Description copied from interface: ControllerService

Start the transport. if true output any errors else do not output errors.

Specified by:

start in interface ControllerService

Parameters:

output - The output (boolean) parameter.

See Also:

start()

startProcessing

public void startProcessing(boolean output)

Parameters:

output - The output (boolean) parameter.

stop

public void stop()

Stop.

Specified by:

stop in interface ControllerService

See Also:

stop(boolean)

stop

public void stop(boolean output)

Description copied from interface: ControllerService

Stop the transport. if true output any errors else do not output errors.

Specified by:

stop in interface ControllerService

Parameters:

See Also:

stop()

trace

public void trace(java.lang.String debugMessage)

transportChanged

public void transportChanged(TransportService transportService,
                             java.lang.Object timestamp,
                             int newState,
                             int oldState)

Description copied from interface: TransportListener

This method will be called when the state of the TransportService changes. Since other notifications are blocked until this method returns, implementors of this method should:

• Not cause the device or transport to be blocked (eg calling read on a measuremnt).
• Handle this call quickly and return.

Because of the multiple threads and quickly changing states, the current state of the transport may not be the same as the newState input parameter. org.eclipse.soda.dk.transport.service.TransportService java.lang.Object The new state of the TransportService when the notification process started. The old state of the TransportService.

Specified by:

transportChanged in interface TransportListener

Parameters:

transportService - The transport service (TransportService) parameter.

timestamp - The timestamp (Object) parameter.

newState - The new state (int) parameter.

oldState - The old state (int) parameter.

transportChangedSend

public void transportChangedSend(TransportService source,
                                 java.lang.Object timestamp,
                                 int newState,
                                 int oldState)

Parameters:

source - The source (TransportService) parameter.

timestamp - The timestamp (Object) parameter.

newState - The new state (int) parameter.

oldState - The old state (int) parameter.
