submit

public <T> ListenableFuture<T> submit(java.util.concurrent.Callable<T> task)

Specified by:

submit in interface java.util.concurrent.ExecutorService

Specified by:

invokeAll

public <T> java.util.List<java.util.concurrent.Future<T>> invokeAll(java.util.Collection<? extends java.util.concurrent.Callable<T>> tasks)
                                                             throws java.lang.InterruptedException

Description copied from interface: ListeningExecutorService

All elements in the returned list must be ListenableFuture instances. The easiest way to obtain a List<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 interface java.util.concurrent.ExecutorService

Specified by:

invokeAll in interface ListeningExecutorService

Overrides:

invokeAll in class java.util.concurrent.AbstractExecutorService

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:

java.lang.InterruptedException

invokeAll

public <T> java.util.List<java.util.concurrent.Future<T>> invokeAll(java.util.Collection<? extends java.util.concurrent.Callable<T>> tasks,

Specified by:

invokeAll in interface java.util.concurrent.ExecutorService

Specified by:

invokeAll in interface ListeningExecutorService

Overrides:

invokeAll in class java.util.concurrent.AbstractExecutorService

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:

java.lang.InterruptedException
