Method Detail

submit

<T> ListenableFuture<T> submit(Callable<T> task)

Specified by:

submit in interface ExecutorService

Returns:

a ListenableFuture representing pending completion of the task

Throws:

RejectedExecutionException

submit

ListenableFuture<?> submit(Runnable task)

Specified by:

submit in interface ExecutorService

Returns:

a ListenableFuture representing pending completion of the task

Throws:

RejectedExecutionException

submit

<T> ListenableFuture<T> submit(Runnable task,
                               T result)

Specified by:

submit in interface ExecutorService

Returns:

a ListenableFuture representing pending completion of the task

Throws:

RejectedExecutionException

invokeAll

<T> List<Future<T>> invokeAll(Collection<? extends Callable<T>> tasks)
                          throws InterruptedException

All elements in the returned list must be ListenableFuture instances.

Specified by:

invokeAll in interface ExecutorService

Returns:

A list of ListenableFuture instances representing the tasks, in the same sequential order as produced by the iterator for the given task list, each of which has completed.

Throws:

RejectedExecutionException

NullPointerException - if any task is null

InterruptedException

invokeAll

<T> List<Future<T>> invokeAll(Collection<? extends Callable<T>> tasks,
                              long timeout,
                              TimeUnit unit)
                          throws InterruptedException

All elements in the returned list must be ListenableFuture instances.

Specified by:

invokeAll in interface ExecutorService

Returns:

a list of ListenableFuture instances representing the tasks, in the same sequential order as produced by the iterator for the given task list. If the operation did not time out, each task will have completed. If it did time out, some of these tasks will not have completed.

Throws:

RejectedExecutionException

NullPointerException - if any task is null

InterruptedException
