    • Method Detail

      • schedule

        public java.util.concurrent.Future<?> schedule​(java.lang.Runnable task,
                                               long delay,
                                               java.util.concurrent.TimeUnit unit)
        Creates and executes a one-shot action that becomes enabled after the given delay.
        Parameters:
        task - the task to execute
        delay - the time from now to delay execution
        unit - the time unit of the delay parameter
        Returns:
        a Future representing pending completion of the task and whose get() method will return null upon completion

      • scheduleWithFixedDelay

        public java.util.concurrent.Future<?> scheduleWithFixedDelay​(java.lang.Runnable task,
                                                             long initialDelay,
                                                             long delay,
                                                             java.util.concurrent.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.
        Parameters:
        task - 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
        Returns:
        a Future representing pending completion of the task, and whose get() method will throw an exception upon cancellation
