public class ScheduledRunner extends GSThread
ScheduledRunner is a single daemon thread that wakes up at fixed intervals, to run a single
Runnable task. Calling cancel() method will wake up and terminate this daemon
thread.
Much like Timer but without the overhead of a managed queue of
tasks.
Usage:
ScheduledRunner runner =
new ScheduledRunner( new YourRunnable(), "Runnable Name", 0 /delay/, 1000 /period/);
...
runner.reschedule(2000); //reschedule with a new period
...
runner.cancel(); //cancel - no longer needed
runner = null; //help gc
