@GwtIncompatible public abstract class ForwardingDeque<E> extends ForwardingQueue<E> implements Deque<E>
Warning: The methods of ForwardingDeque forward
indiscriminately to the methods of the delegate. For example,
overriding ForwardingCollection.add(E) alone will not change the behavior of ForwardingQueue.offer(E) which can lead to unexpected behavior. In this case, you should
override offer as well.
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 ForwardingDeque.
