Interface ShortPriorityQueue

All Superinterfaces:
PriorityQueue<java.lang.Short>
All Known Implementing Classes:
AbstractShortPriorityQueue, ShortArrayFIFOQueue, ShortArrayPriorityQueue, ShortHeapPriorityQueue, ShortPriorityQueues.SynchronizedPriorityQueue

public interface ShortPriorityQueue
extends PriorityQueue<java.lang.Short>
A type-specific PriorityQueue; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens comparator().

    Please use the corresponding type-specific method instead.
    short dequeueShort()
    Dequeues the first element from the queue.
    void enqueue​(short x)
    Enqueues a new element.
    default void enqueue​(java.lang.Short x)

    short firstShort()
    Returns the first element of the queue.
    default java.lang.Short last()
    Deprecated.
    Please use the corresponding type-specific method instead.
    default short lastShort()
