Class AbstractListeningExecutorService

java.lang.Object

com.google.common.util.concurrent.AbstractListeningExecutorService

All Implemented Interfaces:

ListeningExecutorService, java.util.concurrent.Executor, java.util.concurrent.ExecutorService

@Beta
public abstract class AbstractListeningExecutorService
extends java.lang.Object
implements ListeningExecutorService

Implements ListeningExecutorService execution methods atop the abstract Executor.execute(java.lang.Runnable) method. More concretely, the submit, invokeAny and invokeAll methods create ListenableFutureTask instances and pass them to Executor.execute(java.lang.Runnable).

In addition to Executor.execute(java.lang.Runnable), subclasses must implement all methods related to shutdown and termination.

Since:

14.0

Description copied from interface: ListeningExecutorService

All elements in the returned list must be ListenableFuture instances.

Specified by:

invokeAll in interface ListeningExecutorService

Specified by:

invokeAll in interface java.util.concurrent.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:

java.lang.InterruptedException
