java.lang.Object
org.apache.commons.collections4.collection.SynchronizedCollection<E>
org.apache.commons.collections4.bag.SynchronizedBag<E>
org.apache.commons.collections4.bag.SynchronizedSortedBag<E>
Type Parameters:
E - the type of elements in this bag
All Implemented Interfaces:
Serializable, Iterable<E>, Collection<E>, Bag<E>, SortedBag<E>
public class SynchronizedSortedBag<E> extends SynchronizedBag<E> implements SortedBag<E>
Decorates another SortedBag to synchronize its behavior for a multithreaded environment.
