Package it.unimi.dsi.fastutil.bytes

Interface BytePriorityQueue

All Superinterfaces:
it.unimi.dsi.fastutil.PriorityQueue<java.lang.Byte>
All Known Implementing Classes:
AbstractBytePriorityQueue, ByteArrayFIFOQueue, ByteArrayPriorityQueue, ByteHeapPriorityQueue, BytePriorityQueues.SynchronizedPriorityQueue
public interface BytePriorityQueue
extends it.unimi.dsi.fastutil.PriorityQueue<java.lang.Byte>
A type-specific PriorityQueue; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens comparator().

  • Method Summary

    Modifier and Type Method Description
    ByteComparator comparator()
    Returns the comparator associated with this priority queue, or null if it uses its elements' natural ordering.
    default java.lang.Byte dequeue()
    Deprecated.
    Please use the corresponding type-specific method instead.
    byte dequeueByte()
    Dequeues the first element from the queue.
    void enqueue​(byte x)
    Enqueues a new element.
    default void enqueue​(java.lang.Byte x)
    Deprecated.
    Please use the corresponding type-specific method instead.
    default java.lang.Byte first()
    Deprecated.
    Please use the corresponding type-specific method instead.
    byte firstByte()
    Returns the first element of the queue.
    default java.lang.Byte last()
    Deprecated.
    Please use the corresponding type-specific method instead.
    default byte lastByte()
    Returns the last element of the queue, that is, the element the would be dequeued last (optional operation).

  • Method Details

    • enqueue

      void enqueue​(byte x)
      Enqueues a new element.
      Parameters:
      x - the element to enqueue.

      PriorityQueue.enqueue(Object)

    • dequeueByte

      byte dequeueByte()
      Dequeues the first element from the queue.
      Returns:
      the dequeued element.
      Throws:
      java.util.NoSuchElementException - if the queue is empty.

      dequeue()

    • firstByte

      byte firstByte()
      Returns the first element of the queue.
      Returns:
      the first element.
      Throws:
      java.util.NoSuchElementException - if the queue is empty.
      See Also:
      first()

    • lastByte

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

      This default implementation just throws an UnsupportedOperationException.

      Returns:
      the last element.
      Throws:
      java.util.NoSuchElementException - if the queue is empty.
      See Also:
      last()

    • comparator

      ByteComparator comparator()
      Returns the comparator associated with this priority queue, or null if it uses its elements' natural ordering.
      Specified by:
      comparator in interface it.unimi.dsi.fastutil.PriorityQueue<java.lang.Byte>
      Returns:
      the comparator associated with this priority queue.
      See Also:
      PriorityQueue.comparator()
      API Notes:
      Note that this specification strengthens the one given in PriorityQueue.comparator().
