Method Detail

enqueue

public void enqueue(byte x)

Description copied from interface: BytePriorityQueue

Enqueues a new element.

Specified by:

enqueue in interface BytePriorityQueue

Parameters:

x - the element to enqueue.

See Also:

PriorityQueue.enqueue(Object)

dequeueByte

public byte dequeueByte()

Description copied from interface: BytePriorityQueue

Dequeues the first element from the queue.

Specified by:

dequeueByte in interface BytePriorityQueue

Returns:

the dequeued element.

See Also:

BytePriorityQueue.dequeue()

firstByte

public byte firstByte()

Description copied from interface: BytePriorityQueue

Returns the first element of the queue.

Specified by:

firstByte in interface BytePriorityQueue

Returns:

the first element.

See Also:

BytePriorityQueue.first()

lastByte

public byte lastByte()

Description copied from interface: BytePriorityQueue

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.

Specified by:

lastByte in interface BytePriorityQueue

Returns:

the last element.

See Also:

BytePriorityQueue.last()

isEmpty

public boolean isEmpty()

Description copied from interface: PriorityQueue

Checks whether this queue is empty.

This default implementation checks whether PriorityQueue.size() is zero.

Specified by:

isEmpty in interface PriorityQueue<Byte>

Returns:

true if this queue is empty.

size

public int size()

Description copied from interface: PriorityQueue

Returns the number of elements in this queue.

Specified by:

size in interface PriorityQueue<Byte>

Returns:

the number of elements in this queue.

clear

public void clear()

Description copied from interface: PriorityQueue

Removes all elements from this queue.

Specified by:

clear in interface PriorityQueue<Byte>

changed

public void changed()

Description copied from interface: PriorityQueue

Notifies the queue that the first element has changed (optional operation).

This default implementation just throws an UnsupportedOperationException.

Specified by:

changed in interface PriorityQueue<Byte>

comparator

public ByteComparator comparator()

Description copied from interface: BytePriorityQueue

Returns the comparator associated with this priority queue, 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 BytePriorityQueue

Specified by:

comparator in interface PriorityQueue<Byte>

Returns:

the comparator associated with this priority queue.

See Also:

PriorityQueue.comparator()

enqueue

@Deprecated
public void enqueue(Byte x)

Deprecated.

Description copied from interface: BytePriorityQueue

Enqueues a new element.

This default implementation delegates to the corresponding type-specific method.

enqueue in interface PriorityQueue<Byte>

Parameters:

x - the element to enqueue.

dequeue

@Deprecated
public Byte dequeue()

Deprecated.

Description copied from interface: BytePriorityQueue

dequeue in interface PriorityQueue<Byte>

Returns:

the dequeued element.

first

@Deprecated
public Byte first()

Deprecated.

Description copied from interface: BytePriorityQueue

Returns the first element of the queue.

the first element.

last

@Deprecated
public Byte last()

Deprecated.

Description copied from interface: BytePriorityQueue

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.

This default implementation delegates to the corresponding type-specific method.

Specified by:

last in interface BytePriorityQueue

Specified by:

last in interface PriorityQueue<Byte>

Returns:

the last element.

hashCode
