Field Detail

TRANSPORT_STARTED_VALUE

public static final java.lang.Integer TRANSPORT_STARTED_VALUE

Constructor Detail

Controller

public Controller(Transport transport,
                  int priority)

Constructs a standard Notification object. The transport (Transport) parameter. The priority (int) parameter.

Parameters:

transport - The transport (Transport) parameter.

priority - The priority (int) parameter.

Method Detail

enqueue

public void enqueue(java.lang.Object object)

Perform the enqueue action method. java.lang.Object

Parameters:

object - The object (Object) parameter.

enqueueFirst

public void enqueueFirst(java.lang.Object object)

Perform the enqueueFirst action method. java.lang.Object

Parameters:

object - The object (Object) parameter.

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)

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)

Error occurred with the specified source, timestamp and data parameters. The source (Object) parameter. The timestamp (Object) parameter. The data (Object) parameter.

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)

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

Sets the queue size problem value. The queue size problem (int) parameter.

Parameters:

queueSizeProblem - The queue size problem (int) parameter.

See Also:

stop(boolean)

stop

public void stop(boolean output)

Stop with the specified output parameter. The output (boolean) parameter.

Specified by:

stop in interface ControllerService

Parameters:

transportChanged

public void transportChanged(TransportService transportService,
                             java.lang.Object timestamp,

                             int oldState)

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)

This method will be called when the state of the TransportService changes. org.eclipse.soda.dk.transport.service.TransportService java.lang.Object The new state of the TransportService. The old state of the TransportService.

Parameters:

source - The source (TransportService) parameter.
