SynchronizedQueue (The Adobe AEM Quickstart and Web Application. 6.6.0)

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:

java.io.Serializable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.Queue<E>
```
public class SynchronizedQueue<E>
extends SynchronizedCollection<E>
implements java.util.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.
