Interface ConcurrentCollection<T>

Type Parameters:
T - the type of objects held in this ConcurrentCollection
All Known Implementing Classes:
ConcurrentLinkedDequeCollection, ConcurrentLinkedQueueCollection, ConcurrentStackCollection, MultithreadConcurrentQueueCollection
public interface ConcurrentCollection<T>
An adapter interface to a concurrent collection that provides 4 access methods: offerFirst(T), offerLast(T), pollFirst(), and pollLast(). If the implementing subclass delegates the above methods to a Collection that does not have native implementation for offerFirst() or pollLast() it can implement these methods in the same way as offerLast() or pollFirst(), and the vice versa.
