E - the type of elements held in this collection@GwtIncompatible public abstract class ForwardingBlockingQueue<E> extends ForwardingQueue<E> implements BlockingQueue<E>
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.
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 ForwardingBlockingQueue.
