public interface CommandListener
extends ErrorListener

The CommandListener interface defines the methods to be called when event notification occurs. A CommandListener is implemented by any class which wishes to be notified whenever a particular CommandService is executed. This can be useful for a GUI, which may wish to update, when a particular CommandService, such as the power on/off command is executed.

Method Detail

commandExecuted

void commandExecuted(CommandService source,
                     java.lang.Object timestamp,
                     java.lang.Object data)

This method is fired to all Listeners each time the command is executed. 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.

Parameters:

source - CommandService which was executed.

timestamp - The time at which the command execution was detected.

data - Any data which was contained within the command.
