The PriorityQueue class implements priority queues using a heap. To prioritize elements of type A there must be an implicit Ordering [A] available at creation.

The PriorityQueue class implements priority queues using a heap. To prioritize elements of type A there must be an implicit Ordering [A] available at creation.

If multiple elements have the same priority in the ordering of this PriorityQueue, no guarantees are made regarding the order in which elements are returned by dequeue or dequeueAll. In particular, that means this class does not guarantee first in first out behaviour that may be incorrectly inferred from the Queue part of the name of this class.

Only the dequeue and dequeueAll methods will return elements in priority order (while removing elements from the heap). Standard collection methods including drop, iterator, and toString will remove or traverse the heap in whichever order seems most convenient.

Therefore, printing a PriorityQueue will not reveal the priority order of the elements, though the highest-priority element will be printed first. To print the elements in order, one must duplicate the PriorityQueue (by using clone, for instance) and then dequeue them:

Type parameters

A

type of the elements in this priority queue.

Value parameters

ord

implicit ordering used to compare the elements of type A.

Attributes

Example 
val pq = collection.mutable.PriorityQueue(1, 2, 5, 3, 7)
println(pq)                  // elements probably not in order
println(pq.clone.dequeueAll) // prints ArraySeq(7, 5, 3, 2, 1)
