public interface MultiplexSignalListener
extends SignalListener

The SignalListener interface defines the methods to be called when signal notification occurs. A SignalListener is implemented by any class which wishes to be notified whenever a particular SignalService is received. This can be useful for a GUI, which may wish to update, when a particular SignalService, such as the RPMs changes.

Method Detail

signalOccurred

void signalOccurred(SignalService source,
                    java.lang.Object timestamp,
                    ChannelService channel,
                    java.lang.Object data)

This method is fired to all Listeners each time the signal triggered. The signal can be triggered when a message is received from the hardware or when the trigger method is invoked by the application. Since other notifications are blocked until this method returns, implementors of this method should:

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

Parameters:

source - The source (SignalService) parameter.

timestamp - The time stamp (Object) parameter.

channel - The channel (ChannelService) parameter.

data - The data (Object) parameter.
