enqueue
public void enqueue(byte x) Description copied from interface:BytePriorityQueueEnqueues a new element.- Specified by:
enqueuein interfaceBytePriorityQueue- Parameters:
x- the element to enqueue.- See Also:
-
dequeueByte
public byte dequeueByte()Description copied from interface:BytePriorityQueueDequeues the first element from the queue.- Specified by:
dequeueBytein interfaceBytePriorityQueue- Returns:
- the dequeued element.

firstByte
public byte firstByte()Description copied from interface:BytePriorityQueueReturns the first element of the queue.- Specified by:
firstBytein interfaceBytePriorityQueue- Returns:
- the first element.

lastByte
public byte lastByte()Description copied from interface:BytePriorityQueueReturns the last element of the queue, that is, the element the would be dequeued last (optional operation).This default implementation just throws an
UnsupportedOperationException.- Specified by:
lastBytein interfaceBytePriorityQueue- Returns:
- the last element.

isEmpty
public boolean isEmpty()Description copied from interface:PriorityQueueChecks whether this queue is empty.This default implementation checks whether
PriorityQueue.size()is zero.- Specified by:
isEmptyin interfacePriorityQueue<Byte>- Returns:
- true if this queue is empty.
-
size
public int size()Description copied from interface:PriorityQueueReturns the number of elements in this queue.- Specified by:
sizein interfacePriorityQueue<Byte>- Returns:
- the number of elements in this queue.
-
clear
public void clear()Description copied from interface:PriorityQueueRemoves all elements from this queue.- Specified by:
clearin interfacePriorityQueue<Byte>

changed
public void changed()Description copied from interface:PriorityQueueNotifies the queue that the first element has changed (optional operation).This default implementation just throws an
UnsupportedOperationException.- Specified by:
changedin interfacePriorityQueue<Byte>

comparator
Description copied from interface:BytePriorityQueueReturns the comparator associated with this priority queue, or null if it uses its elements' natural ordering.- Specified by:
comparatorin interfaceBytePriorityQueue- Specified by:
comparatorin interfacePriorityQueue<Byte>- Returns:
- the comparator associated with this priority queue.
