All Implemented Interfaces:

java.io.Serializable, java.lang.Iterable<E>, java.util.Collection<E>, Bag<E>, SortedBag<E>

public class SynchronizedSortedBag<E>
extends SynchronizedBag<E>
implements SortedBag<E>

Decorates another SortedBag to synchronize its behaviour for a multi-threaded environment.

Methods are synchronized, then forwarded to the decorated bag. Iterators must be separately synchronized around the loop.

This class is Serializable from Commons Collections 3.1.

Since:

3.0
