public interface DoublePriorityQueue
A type-specific PriorityQueue
; provides some additional methods that use polymorphism to avoid (un)boxing.
Additionally, this interface strengthens comparator()
.
Method Summary | |
---|---|
DoubleComparator |
comparator()
Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering. |
double |
dequeueDouble()
Dequeues the first element from the queue. |
void |
enqueue(double x)
Enqueues a new element. |
double |
firstDouble()
Returns the front element of the queue. |
double |
lastDouble()
