SynchronizedCollection ("The Adobe AEM Quickstart and Web Application.")

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

Direct Known Subclasses:

SynchronizedBag, SynchronizedMultiSet
```
public class SynchronizedCollection<E>
extends java.lang.Object
implements java.util.Collection<E>, java.io.Serializable
```
Decorates another Collection to synchronize its behaviour for a multi-threaded environment.
Iterators must be manually synchronized:
```
 synchronized (coll) {
   Iterator it = coll.iterator();
   // do stuff with iterator
 }
 
```
This class is Serializable from Commons Collections 3.1.
Since:

3.0
