java.lang.Object org.springframework.scheduling.timer.ScheduledTimerTask
JavaBean that describes a scheduled TimerTask, consisting of the TimerTask itself and a delay plus period. Period needs to be specified; there is no point in a default for it.
The J2SE Timer does not offer more sophisticated scheduling options like cron expressions. Consider using Quartz for such demanding needs.
Note that Timer uses a TimerTask instance that is shared between repeated executions, in contrast to Quartz which instantiates a new Job for each execution.

void |
setDelay(long delay)
Set the delay before starting the task for the first time, in milliseconds. |
void |
setFixedRate(boolean fixedRate)
Set whether to schedule as fixed-rate execution, rather than fixed-delay execution. |
void |
setPeriod(long period)
