方法详细资料

schedule

ScheduledFuture<?> schedule(Runnable command,
                            long delay,
                            TimeUnit unit)

Creates and executes a one-shot action that becomes enabled after the given delay.

参数:

command - the task to execute

delay - the time from now to delay execution

unit - the time unit of the delay parameter

返回:

a ScheduledFuture representing pending completion of the task and whose get() method will return null upon completion scheduled for execution

scheduleAtFixedRate

ScheduledFuture<?> scheduleAtFixedRate(Runnable command,
                                       long initialDelay,
                                       long period,
                                       TimeUnit unit)

Creates and executes a periodic action that becomes enabled first after the given initial delay, and subsequently with the given period; that is executions will commence after initialDelay then initialDelay+period, then initialDelay + 2 * period, and so on. If any execution of the task encounters an exception, subsequent executions are suppressed. Otherwise, the task will only terminate via cancellation or termination of the executor. If any execution of this task takes longer than its period, then subsequent executions may start late, but will not concurrently execute.

参数:

command - the task to execute

initialDelay - the time to delay first execution

period - the period between successive executions

unit - the time unit of the initialDelay and period parameters

返回:

a ScheduledFuture representing pending completion of the task, and whose get() method will throw an exception upon cancellation

scheduleWithFixedDelay

ScheduledFuture<?> scheduleWithFixedDelay(Runnable command,
                                          long initialDelay,
                                          long delay,
                                          TimeUnit unit)

Creates and executes a periodic action that becomes enabled first after the given initial delay, and subsequently with the given delay between the termination of one execution and the commencement of the next. If any execution of the task encounters an exception, subsequent executions are suppressed. Otherwise, the task will only terminate via cancellation or termination of the executor.

参数:

command - the task to execute

initialDelay - the time to delay first execution

delay - the delay between the termination of one execution and the commencement of the next

unit - the time unit of the initialDelay and delay parameters

返回:

a ScheduledFuture representing pending completion of the task, and whose get() method will throw an exception upon cancellation

shutdown

void shutdown()
