DoubleLinkedQueue< E>.from constructor
Creates a double-linked queue containing all elements
.
The element order in the queue is as if the elements were added using
addLast in the order provided by elements.iterator
.
All the elements
should be instances of E
.
The elements
iterable itself may have any element type, so this
constructor can be used to down-cast a Queue
, for example as:
Queue<SuperType> superQueue = ...;
Queue<SubType> subQueue =
new DoubleLinkedQueue<SubType>.from(superQueue.whereType<SubType>());
Implementation
factory DoubleLinkedQueue.from(Iterable elements) {
Queue<E> list = new DoubleLinkedQueue<E>();
for (final e in elements) {
list.addLast(e);
}
return list;
}
