Method Detail
-
enqueue
void enqueue(float x)
Enqueues a new element.- Parameters:
x
- the element to enqueue.- See Also:
PriorityQueue.enqueue(Object)
-
dequeueFloat
float dequeueFloat()
Dequeues the first element from the queue.- Returns:
- the dequeued element.
- Throws:
java.util.NoSuchElementException
- if the queue is empty.- See Also:
dequeue()
-
firstFloat
float firstFloat()
Returns the first element of the queue.- Returns:
- the first element.
- Throws:
java.util.NoSuchElementException
- if the queue is empty.- See Also:
first()
-
lastFloat
default float lastFloat()
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
FloatComparator comparator()
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 interfacePriorityQueue<java.lang.Float>
- Returns:
- the comparator associated with this priority queue.
- See Also:
PriorityQueue.comparator()
-
enqueue
@Deprecated default void enqueue(java.lang.Float x)
Deprecated.Please use the corresponding type-specific method instead.Enqueues a new element.This default implementation delegates to the corresponding type-specific method.

enqueue
in interfacePriorityQueue<java.lang.Float>
- Parameters:
x
- the element to enqueue.
-
dequeue
@Deprecated default java.lang.Float dequeue()

- Specified by:
dequeue
in interfacePriorityQueue<java.lang.Float>
- Returns:
- the dequeued element.
-
first
@Deprecated default java.lang.Float first()
Deprecated.Please use the corresponding type-specific method instead.Returns the first element of the queue.This default implementation delegates to the corresponding type-specific method.
- Specified by:
first
in interfacePriorityQueue<java.lang.Float>
- Returns:
- the first element.
-
last
@Deprecated default java.lang.Float last()
Deprecated.Please use the corresponding type-specific method instead.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 interfacePriorityQueue<java.lang.Float>
