ForwardingDeque (lettuce 4.3.3.Final API)

java.lang.Object
- com.lambdaworks.redis.internal.ForwardingDeque<E>

All Implemented Interfaces:

Iterable<E>, Collection<E>, Deque<E>, Queue<E>

Direct Known Subclasses:

FastCountingDeque
```
public abstract class ForwardingDeque<E>
extends Object
implements Deque<E>
```
Delegating Deque allowing to override particular methods and not changing the underlying Deque behavior. This class is applying the decorator pattern to the underlying Deque.
