class
Queue
[A]
extends
java.lang.Object with
scala.collection.mutable.MutableList[A] with
scala.ScalaObjectQueue
objects implement data structures that allow to
insert and retrieve elements in a first-in-first-out (FIFO) manner.Constructor Summary | |

|
Def Summary | |
def
++=
(it: scala.Iterator[A])
: scala.Unit
Adds all elements provided by an iterator at the end of the queue. The elements are prepended in the order they are given out by the iterator. |
|
def
++=
(iter: scala.Iterable[A])
: scala.Unit
Adds all elements provided by an Iterable object
at the end of the queue. The elements are prepended in the order they
are given out by the iterator.
|
|
def
+=
(elem: A)
: scala.Unit
Inserts a single element at the end of the queue. |
|
def
clear
: scala.Unit
Removes all elements from the queue. After this operation is completed, the queue will be empty. |
|
override
|
def
clone
: scala.collection.mutable.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: scala.Function1[A, scala.Boolean])
: scala.Seq[A]
Returns all elements in the queue which satisfy the given predicate, and removes those elements from the queue. |
|
def
dequeueFirst
(p: scala.Function1[A, scala.Boolean])
: scala.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*)
: scala.Unit
Adds all elements to the queue. |
|
override
|
def
equals
(that: scala.Any)
: scala.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
: scala.Int
The hashCode method always yields an error, since it is not safe to use mutable queues as keys in hash tables. |
override
|
def
isEmpty
: scala.Boolean
Checks if the queue is empty. |
override
|
def
toString
: java.lang.String
Returns a textual representation of a queue as a string. |
