java.lang.Object
- org.apache.commons.collections4.collection.SynchronizedCollection<E>
- - org.apache.commons.collections4.queue.SynchronizedQueue<E>

Type Parameters:

E - the type of the elements in the collection

All Implemented Interfaces:

Serializable, Iterable<E>, Collection<E>, Queue<E>
```
public class SynchronizedQueue<E>
extends SynchronizedCollection<E>
implements Queue<E>
```
Decorates another Queue to synchronize its behaviour for a multi-threaded environment.
Methods are synchronized, then forwarded to the decorated queue. Iterators must be separately synchronized around the loop.
