public interface TransportListener
extends MessageListener

The TransportListener interface defines the methods to be called when event notification occurs. A TransportListener Interface is implemented by anyone who wishes to be notified whenever a valid MessageService is received by the Transport.

Method Detail

transportChanged

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

Parameters:

transportService - The transport service (TransportService) parameter.

timestamp - The timestamp (Object) parameter.

newState - The new state (int) parameter.

oldState - The old state (int) parameter.
