RunnableFuture

AI-generated Key Takeaways

RunnableFuture combines the capabilities of Runnable and Future, allowing an asynchronous computation to be executed and its result retrieved.
Running the run() method marks the Future as complete and makes its result accessible.
RunnableFuture supports cancellation and provides methods to check completion status and retrieve results.
Key implementations include FutureTask and RunnableScheduledFuture.

public interface RunnableFuture implements Runnable Future<V>

Known Indirect Subclasses

FutureTask<V>, RunnableScheduledFuture<V>

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

Public Method Summary

abstract void

run()

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

Inherited Method Summary

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.
