public interface IntPriorityQueue
A type-specific PriorityQueue
; provides some additional methods that use polymorphism to avoid (un)boxing.
Additionally, this interface strengthens comparator()
.
Method Summary | |
---|---|
IntComparator |
comparator()
Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering. |
int |
dequeueInt()
Dequeues the first element from the queue. |
void |
enqueue(int x)
Enqueues a new element. |
int |
firstInt()
Returns the first element of the queue. |
int |
lastInt()
Returns the last element of the queue, that is, the element the would be dequeued last (optional operation). |
