Class ForwardingListeningExecutorService

java.lang.Object

com.google.common.collect.ForwardingObject

com.google.common.util.concurrent.ForwardingExecutorService

com.google.common.util.concurrent.ForwardingListeningExecutorService

All Implemented Interfaces:

ListeningExecutorService, AutoCloseable, Executor, ExecutorService

@GwtIncompatible
public abstract class ForwardingListeningExecutorService
extends ForwardingExecutorService
implements ListeningExecutorService

A listening executor service which forwards all its method calls to another listening executor service. Subclasses should override one or more methods to modify the behavior of the backing executor service as desired per the decorator pattern.

default method warning: This class does not forward calls to default methods. Instead, it inherits their default implementations. When those implementations invoke methods, they invoke methods on the ForwardingListeningExecutorService.

Method Details

delegate

protected abstract ListeningExecutorService delegate()

Description copied from class: ForwardingObject

Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
