E - type of the elementSerializable, Iterable<E>, Collection<E>, Queue<E>public class BoundedPriorityQueue<E> extends AbstractQueue<E> implements Serializable
PriorityQueue.
Note: elements are returned in reverse order.
For instance, if "top N smallest elements" are required, use new BoundedPriorityQueue(N),
and the elements would be returned in largest to smallest order.| Constructor | Description |

BoundedPriorityQueue(int maxSize) |
Creates a bounded priority queue with the specified maximum size and default ordering.
