Class java.util.concurrent.ScheduledExecutorService

Examples of java.util.concurrent.ScheduledExecutorService.scheduleAtFixedRate()

java.util.concurrent.ScheduledExecutorService.scheduleAtFixedRate()
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 {@code initialDelay} then {@code initialDelay+period}, then {@code 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. @param command the task to execute @param initialDelay the time to delay first execution @param period the period between successive executions @param unit the time unit of the initialDelay and period parameters @return a ScheduledFuture representing pending completion ofthe task, and whose {@code get()} method will throw anexception upon cancellation @throws RejectedExecutionException if the task cannot bescheduled for execution @throws NullPointerException if command is null @throws IllegalArgumentException if period less than or equal to zero
