RunnableScheduledFuture

AI-generated Key Takeaways

• RunnableScheduledFuture combines the capabilities of RunnableFuture and ScheduledFuture, allowing tasks to be executed on a schedule.

• Executing the run method marks the Future as complete and makes the results accessible.

• The isPeriodic() method indicates whether the task is scheduled for repeated execution or a single run.

• This interface inherits methods from RunnableFuture, ScheduledFuture, and other related interfaces, providing functionalities like cancellation, result retrieval, and delay management.

public interface RunnableScheduledFuture implements RunnableFuture<V> ScheduledFuture<V>

A ScheduledFuture that is Runnable. Successful execution of the run method causes completion of the Future and allows access to its results.

Public Method Summary

abstract boolean

isPeriodic() Returns true if this task is periodic.

Inherited Method Summary

From interface java.util.concurrent.RunnableFuture

abstract void

run() Sets this Future to the result of its computation unless it has been cancelled.

From interface java.lang.Runnable

abstract void

run() When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread.

From interface java.util.concurrent.Future

abstract boolean	cancel(boolean mayInterruptIfRunning) Attempts to cancel execution of this task.
abstract V	get(long timeout, TimeUnit unit) Waits if necessary for at most the given time for the computation to complete, and then retrieves its result, if available.
abstract V	get() Waits if necessary for the computation to complete, and then retrieves its result.
abstract boolean	isCancelled() Returns true if this task was cancelled before it completed normally.
abstract boolean	isDone() Returns true if this task completed.

From interface java.util.concurrent.Delayed

abstract long

getDelay(TimeUnit unit) Returns the remaining delay associated with this object, in the given time unit.

From interface java.lang.Comparable

abstract int

compareTo(Delayed o) Compares this object with the specified object for order.

Public Methods

public abstract boolean isPeriodic ()

Returns true if this task is periodic. A periodic task may re-run according to some schedule. A non-periodic task can be run only once.

Returns

• true if this task is periodic
