BoundedPriorityQueue

class BoundedPriorityQueue[A] extends Iterable[A] with Growable[A] with Serializable

Bounded priority queue. This class wraps the original PriorityQueue class and modifies it such that only the top K elements are retained. The top K elements are defined by an implicit Ordering[A].
