class SynchronizedQueue
[source: scala/collection/mutable/SynchronizedQueue.scala]
class SynchronizedQueue[A]
extends Queue[A]
This is a synchronized version of the Queue[T] class. It implements a data structure that allows one to insert and retrieve elements in a first-in-first-out (FIFO) manner.

Method Summary
override def ++= (iter : Traversable[A]) : SynchronizedQueue[A]
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.
override def ++= (it : Iterator[A]) : SynchronizedQueue[A]
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.
override def += (elem : A) : SynchronizedQueue[A]
Inserts a single element at the end of the queue.
override def clear : Unit
Removes all elements from the queue. After this operation is completed, the queue will be empty.
override def dequeue : A
Returns the first element in the queue, and removes this element from the queue.
override def enqueue (elems : A*) : Unit
Adds all elements to the queue.
override def equals (that : Any) : Boolean
Checks if two queues are structurally identical.
override 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 isEmpty : Boolean
Checks if the queue is empty.
override def toString : java.lang.String
Returns a textual representation of a queue as a string.

Method Details
override def isEmpty : Boolean
Checks if the queue is empty.
Returns
true, iff there is no element in the queue.
override def +=(elem : A) : SynchronizedQueue[A]
Inserts a single element at the end of the queue.
Parameters
elem - the element to insert
override def ++=(iter : Traversable[A]) : SynchronizedQueue[A]
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.
Parameters
iter - an iterable object
override def ++=(it : Iterator[A]) : SynchronizedQueue[A]
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.
Parameters
it - an iterator
override def enqueue(elems : A*) : Unit
Adds all elements to the queue.
Parameters
elems - the elements to add.
Overrides
Queue.enqueue
override def dequeue : A
Returns the first element in the queue, and removes this element from the queue.
Returns
the first element of the queue.
Overrides
Queue.dequeue
override def front : A
Returns the first element in the queue, or throws an error if there is no element contained in the queue.
Returns
the first element.
Overrides
Queue.front
override def clear : Unit
Removes all elements from the queue. After this operation is completed, the queue will be empty.
override def equals(that : Any) : Boolean
Checks if two queues are structurally identical.
Returns
true, iff both queues contain the same sequence of elements.
override def toString : java.lang.String
Returns a textual representation of a queue as a string.
Returns
the string representation of this queue.
