Constructor Detail

QueueDevice

protected QueueDevice()

Constructs an BaseQueueDevice object.

Method Detail

getReceivedQueue

public Queue getReceivedQueue()

Gets the Queue receivedQueue property value.

Returns:

Results of the get received queue (Queue) value.

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.

Specified by:

messageReceived in interface MessageListener

Overrides:

messageReceived in class TransportDevice

Parameters:

transportService - The transport that received the message.

timestamp - The timestamp when the message was detected.

message - The message received.

run

public void run()

Perform the run action method.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class Device

See Also:

Runnable.run()

send

public void send(MessageService message)

Perform the send action method.

Specified by:

send in interface DeviceService

Overrides:

send in class TransportDevice

Parameters:

message - org.eclipse.soda.dk.message.service.MessageService

See Also:

DeviceService.send(org.eclipse.soda.dk.message.service.MessageService)

start

public void start()

Perform the start action method.

Specified by:

start in interface DeviceService

Overrides:

start in class TransportDevice

See Also:

DeviceService.start()

stop

public void stop()

Perform the stop action method.

Specified by:

stop in interface DeviceService

Overrides:

stop in class TransportDevice

See Also:

DeviceService.stop()
