All Implemented Interfaces:

ListeningExecutorService, AutoCloseable, Executor, ExecutorService

@CheckReturnValue
@GwtIncompatible
public abstract class AbstractListeningExecutorService
extends AbstractExecutorService
implements ListeningExecutorService

Abstract ListeningExecutorService implementation that creates ListenableFuture instances for each Runnable and Callable submitted to it. These tasks are run with the abstract execute(Runnable) method.

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

Since:

14.0
