Class ForwardingBlockingQueue<E>

java.lang.Object

com.google.common.collect.ForwardingObject

com.google.common.collect.ForwardingCollection<E>

com.google.common.collect.ForwardingQueue<E>

com.google.common.util.concurrent.ForwardingBlockingQueue<E>

Type Parameters:

E - the type of elements held in this collection

All Implemented Interfaces:

Iterable<E>, Collection<E>, BlockingQueue<E>, Queue<E>

public abstract class ForwardingBlockingQueue<E>
extends ForwardingQueue<E>
implements BlockingQueue<E>

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

Since:

4.0
