Uses of Future in java.util.concurrent

 

Subinterfaces of Future in java.util.concurrent
interface	ScheduledFuture<V>           A delayed result-bearing action that can be cancelled.

 

Classes in java.util.concurrent that implement Future
class	FutureTask<V>           A cancellable asynchronous computation.

 

Methods in java.util.concurrent that return Future
Future<V>	ExecutorCompletionService.poll()
Future<V>	CompletionService.poll()           Retrieves and removes the Future representing the next completed task or null if none are present.
Future<V>	ExecutorCompletionService.poll(long timeout, TimeUnit unit)
Future<V>	CompletionService.poll(long timeout, TimeUnit unit)           Retrieves and removes the Future representing the next completed task, waiting if necessary up to the specified wait time if none are yet present.
<T> Future<T>	ScheduledThreadPoolExecutor.submit(Callable<T> task)
<T> Future<T>	ExecutorService.submit(Callable<T> task)           Submits a value-returning task for execution and returns a Future representing the pending results of the task.
<T> Future<T>	AbstractExecutorService.submit(Callable<T> task)
Future<V>	ExecutorCompletionService.submit(Callable<V> task)
Future<V>	CompletionService.submit(Callable<V> task)           Submits a value-returning task for execution and returns a Future representing the pending results of the task.
Future<?>	ScheduledThreadPoolExecutor.submit(Runnable task)
Future<?>	ExecutorService.submit(Runnable task)           Submits a Runnable task for execution and returns a Future representing that task.
Future<?>	AbstractExecutorService.submit(Runnable task)
<T> Future<T>	ScheduledThreadPoolExecutor.submit(Runnable task, T result)
<T> Future<T>	ExecutorService.submit(Runnable task, T result)           Submits a Runnable task for execution and returns a Future representing that task that will upon completion return the given result
<T> Future<T>	AbstractExecutorService.submit(Runnable task, T result)
Future<V>	ExecutorCompletionService.submit(Runnable task, V result)
Future<V>	CompletionService.submit(Runnable task, V result)           Submits a Runnable task for execution and returns a Future representing that task.Upon completion, this task may be taken or polled.
Future<V>	ExecutorCompletionService.take()
Future<V>	CompletionService.take()           Retrieves and removes the Future representing the next completed task, waiting if none are yet present.

 

Methods in java.util.concurrent that return types with arguments of type Future
<T> List<Future<T>>	ExecutorService.invokeAll(Collection<Callable<T>> tasks)           Executes the given tasks, returning a list of Futures holding their status and results when all complete.
<T> List<Future<T>>	AbstractExecutorService.invokeAll(Collection<Callable<T>> tasks)
<T> List<Future<T>>	ExecutorService.invokeAll(Collection<Callable<T>> tasks, long timeout, TimeUnit unit)           Executes the given tasks, returning a list of Futures holding their status and results when all complete or the timeout expires, whichever happens first.
<T> List<Future<T>>	AbstractExecutorService.invokeAll(Collection<Callable<T>> tasks, long timeout, TimeUnit unit)

 

Constructor parameters in java.util.concurrent with type arguments of type Future
ExecutorCompletionService(Executor executor, BlockingQueue<Future<V>> completionQueue)           Creates an ExecutorCompletionService using the supplied executor for base task execution and the supplied queue as its completion queue.
