Class TimerAdapter

  +--sale.events.TimerAdapter

public abstract class TimerAdapter

extends Object

implements TimerListener, SerializableListener

An abstract adapter class for receiving timer events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Extend this class to create a TimerEvent listener and override the methods for the events of interest. (If you implement the TimerListener interface, you have to define all of the methods in it. This abstract class defines empty method bodies for them all, so you can concentrate on defining methods only for events you care about.)

Create a listener object using the extended class and then register it with a Timer using the Timer's Timer.addTimerListener(sale.events.TimerListener) method. When a timer event occurs, the relevant method in the listener object is invoked, and a TimerEvent is passed to it.
