Queue
objects implement data structures that allow to
insert and retrieve elements in a first-in-first-out (FIFO) manner.
Method Summary | |
def ++=(iter: Iterable[A]): Unit
Adds all elements provided by an Iterable object
at the end of the queue.
|
|
def ++=(it: Iterator[A]): Unit
Adds all elements provided by an iterator at the end of the queue. |
|
def +=(elem: A): Unit
Inserts a single element at the end of the queue. |
|
def clear: Unit
Removes all elements from the queue. |
|
override
|
def clone(): Queue[A]
This method clones the queue. |
def dequeue: A
Returns the first element in the queue, and removes this element from the queue. |
|
def dequeueAll(p: (A) => Boolean): Seq[A]
Returns all elements in the queue which satisfy the given predicate, and removes those elements from the queue. |
|
def dequeueFirst(p: (A) => Boolean): Option[A]
Returns the first element in the queue which satisfies the given predicate, and removes this element from the queue. |
|
def enqueue(elems: A*): Unit
Adds all elements to the queue. |
|
override
|
def equals(that: Any): Boolean
Checks if two queues are structurally identical. |
def front: A
Returns the first element in the queue, or throws an error if there is no element contained in the queue. |
|
override
|
def hashCode(): Int
The hashCode method always yields an error, since it is not safe to use mutable queues as keys in hash tables. |
def isEmpty: Boolean
Checks if the queue is empty. |
|
override
|
def toString(): String
Returns a textual representation of a queue as a string. |

Method Detail |
def isEmpty: Boolean
def +=(elem: A): Unit
elem
-
the element to insert
def ++=(iter: Iterable[A]): Unit
Iterable
object
at the end of the queue. The elements are prepended in the order they
are given out by the iterator.
iter
-
an iterable object
def ++=(it: Iterator[A]): Unit
it
-
an iterator
def enqueue(elems: A*): Unit
elems
-
the elements to add.
def dequeue: A
def dequeueFirst(p: (A) => Boolean): Option[A]
p
-
the predicate used for choosing the first element
def dequeueAll(p: (A) => Boolean): Seq[A]
p
-
the predicate used for choosing elements
def front: A
def clear: Unit
override def equals(that: Any): Boolean
