All Implemented Interfaces:

Iterable<T>, Collection<T>, BlockingQueue<T>, Queue<T>

public class GrowableMpScArrayConsumerBlockingQueue<T>
extends AbstractQueue<T>
implements BlockingQueue<T>

This implements a BlockingQueue backed by an array with no fixed capacity.

When the capacity is reached, data will be moved to a bigger array.

This queue only allows 1 consumer thread to dequeue items and multiple producer threads.
