Class GrowableArrayBlockingQueue<T>

  • All Implemented Interfaces:
    java.lang.Iterable<T>, java.util.Collection<T>, java.util.concurrent.BlockingQueue<T>, java.util.Queue<T>
    public class GrowableArrayBlockingQueue<T>
extends java.util.AbstractQueue<T>
implements java.util.concurrent.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.
