Class Timer
public final class Timer
extends java.lang.Object
Timer: an object that executes a
Fireable target object's
fire method at a specified interval.
For example, here's how an application clock might be implemented, where the
application passes in an
Label object as its pane:
private final Label clockPane = (Label) glade.getWidget("clockLabel");
private Timer clock = new Timer(1000, // one second
new Fireable() {
public boolean fire() {
String dateStr = DateFormat.getDateInstance()
.format(new Date());
clockPane.setText(dateStr);
return true; // continue firing
}
});
clock.start();
Note: a Timer generates events on the application's GUI event queue. It
therefore is not accurate for short time periods. It also should only be used
to directly fire short/fast methods. Longer methods need to be executed in a
separate thread.
int | getInterval()- Returns the interval associated with this Timer.
|
boolean | isRunning()- Returns whether this timer is running.
|
void | setInterval(int interval)- Set the interval associated with this Timer.
|
void | start()- Start this timer object; that is, begin executing its fire method at its
specified interval.
|
void | stop()- Stop this timer object; that is, stop executing its fire method at its
specified interval.

Timer
public Timer(int interval,
Fireable target) Create a new Timer object.
interval - the time period between fire method executions,
in thousandths of a second.target - the object whose fire() method gets called after the specified
time period elapses.
getInterval
public final int getInterval()
Returns the interval associated with this Timer.
- the time period between
fire method executions, in
thousandths of a second.
isRunning
public final boolean isRunning()
Returns whether this timer is running.
- true if this timer is currently running.
setInterval
public final void setInterval(int interval)
Set the interval associated with this Timer.
interval - the time period between fire method executions,
in thousandths of a second.
start
public final void start()
Start this timer object; that is, begin executing its fire method at its
specified interval.
stop
public final void stop()
Stop this timer object; that is, stop executing its fire method at its
specified interval. This method does not need to be called if the
fire method returned false.
