invokeAll
All elements in the returned list must be
ListenableFuture
instances. The easiest way to obtain aList<ListenableFuture<T>>
from this method is an unchecked (but safe) cast:@SuppressWarnings("unchecked") // guaranteed by invokeAll contract
List<ListenableFuture<T>> futures = (List) executor.invokeAll(tasks);
- Specified by:
invokeAll
in interfaceExecutorService
- 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.
-
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. The easiest way to obtain aList<ListenableFuture<T>>
from this method is an unchecked (but safe) cast:@SuppressWarnings("unchecked") // guaranteed by invokeAll contract
List<ListenableFuture<T>> futures = (List) executor.invokeAll(tasks, timeout, unit);
- Specified by:
invokeAll
in interfaceExecutorService
- 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.
