Interface BytePriorityQueue

All Superinterfaces:

PriorityQueue<Byte>

All Known Implementing Classes:

AbstractBytePriorityQueue, ByteArrayPriorityQueue, ByteHeapPriorityQueue, BytePriorityQueues.SynchronizedPriorityQueue

public interface BytePriorityQueue
extends PriorityQueue<Byte>

A type-specific PriorityQueue; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens comparator().

Method Summary

ByteComparator	comparator() Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.
byte	dequeueByte() Dequeues the first element from the queue.
void	enqueue(byte x) Enqueues a new element.
byte	firstByte() Returns the front element of the queue.
byte	lastByte() Returns the rear element of the queue, that is, the element the would be dequeued last (optional operation).

Method Detail

enqueue

void enqueue(byte x)

Enqueues a new element.

Parameters:

x - the element to enqueue..

dequeueByte

byte dequeueByte()

Dequeues the first element from the queue.

Returns:

the dequeued element.

Throws:

NoSuchElementException - if the queue is empty.

firstByte

byte firstByte()

Returns the front element of the queue.

Returns:

the front element.

Throws:

NoSuchElementException - if the queue is empty.

lastByte

byte lastByte()

Returns the rear element of the queue, that is, the element the would be dequeued last (optional operation).

Returns:

the rear element.

Throws:

NoSuchElementException - if the queue is empty.

comparator

ByteComparator comparator()

Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.

Note that this specification strengthens the one given in PriorityQueue.comparator().

Specified by:

comparator in interface PriorityQueue<Byte>

Returns:

the comparator associated with this sorted set, or null if it uses its elements' natural ordering.
