Package dev.mccue.guava.concurrent

Class ForwardingExecutorService

java.lang.Object

dev.mccue.guava.collect.ForwardingObject

dev.mccue.guava.concurrent.ForwardingExecutorService

All Implemented Interfaces:

Executor, ExecutorService

Direct Known Subclasses:

ForwardingListeningExecutorService

public abstract class ForwardingExecutorService
extends dev.mccue.guava.collect.ForwardingObject
implements ExecutorService

An executor service which forwards all its method calls to another 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 ForwardingExecutorService.

Since:

10.0
