| Method Summary | |
| public void | cancel()
Terminates this timer, discarding any currently scheduled tasks. | | void | schedule(TimerTask task, long delay)
Schedules the specified task for execution after the specified delay. | | void | schedule(TimerTask task, Date firstTime, long period)
Schedules the specified task for repeated fixed-delay execution,
beginning at the specified time. | | void | schedule(TimerTask task, long delay, long period)
Schedules the specified task for repeated fixed-delay execution,
beginning after the specified delay. |
| cancel | | public void cancel()(Code) | | Terminates this timer, discarding any currently scheduled tasks.
Does not interfere with a currently executing task (if it exists).
Once a timer has been terminated, its execution thread terminates
gracefully, and no more tasks may be scheduled on it.
Note that calling this method from within the run method of a
timer task that was invoked by this timer absolutely guarantees that
the ongoing task execution is the last task execution that will ever
be performed by this timer.
This method may be called repeatedly; the second and subsequent
calls have no effect.

| schedule | | void schedule(TimerTask task, long delay)(Code) | | Schedules the specified task for execution after the specified delay.
Parameters:
task - task to be scheduled.
Parameters:
delay - delay in milliseconds before task is to be executed.
throws:
IllegalArgumentException - if delay is negative, ordelay + System.currentTimeMillis() is negative.
throws:
IllegalStateException - if task was already scheduled orcancelled, or timer was cancelled. |
| schedule | | void schedule(TimerTask task, Date firstTime, long period)(Code) | | Schedules the specified task for repeated fixed-delay execution,
beginning at the specified time. Subsequent executions take place at
approximately regular intervals, separated by the specified period.
In fixed-delay execution, each execution is scheduled relative to
the actual execution time of the previous execution. If an execution
is delayed for any reason (such as garbage collection or other
background activity), subsequent executions will be delayed as well.
In the long run, the frequency of execution will generally be slightly
lower than the reciprocal of the specified period (assuming the system
clock underlying Object.wait(long) is accurate).
Fixed-delay execution is appropriate for recurring activities
that require "smoothness." In other words, it is appropriate for
activities where it is more important to keep the frequency accurate
in the short run than in the long run. This includes most animation
tasks, such as blinking a cursor at regular intervals. It also includes
tasks wherein regular activity is performed in response to human
input, such as automatically repeating a character as long as a key
is held down.
Parameters:
task - task to be scheduled.
Parameters:
firstTime - First time at which task is to be executed.
Parameters:
period - time in milliseconds between successive task executions.
throws:
IllegalArgumentException - if time.getTime() is negative.
throws:
IllegalStateException - if task was already scheduled orcancelled, timer was cancelled, or timer thread terminated. |
