A Queue implementation based on a double-linked list.
Allows constant time add, remove-at-ends and peek operations.

Methods
-
add(
E value) → void -

valueat the end of the queue. -
addAll(
Iterable<E> iterable) → void -
Adds all elements of
iterableat the end of the queue. The length of the queue is extended by the length ofiterable. -
addFirst(
E value) → void -
Adds
valueat the beginning of the queue. -
addLast(
E value) → void -
Adds
valueat the end of the queue. -
any(

inherited
Checks whether any element of this iterable satisfies
test.… -
clear(
) → void -

-
firstEntry(

firstWhere(
bool test(E element), {E orElse()}) → E -
inherited

test.… -
fold(
initialValue, dynamic combine(previousValue, E element)) → dynamic -
inherited
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value…
-
forEach(
void f(E element)) → void -
inherited
Applies the function
fto each element of this collection in iteration order. -
forEachEntry(
void f(DoubleLinkedQueueEntry<E> element)) → void -
join(
[String separator = ""]) → String -
inherited
Converts each element to a String and concatenates the strings.…
-
lastEntry(
) → DoubleLinkedQueueEntry<E> -
lastWhere(
bool test(E element), {E orElse()}) → E -
inherited
Returns the last element that satisfies the given predicate
test.… -
map(
dynamic f(E element)) → Iterable -
inherited
Returns a new lazy Iterable with elements that are created by calling
fon each element of thisIterablein iteration order.… -
reduce(
E combine(E value, E element)) → E -
inherited
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.…
-
remove(
Object o) → bool -
Remove a single instance of
valuefrom the queue.… -
removeFirst(
) → E -
Removes and returns the first element of this queue.…
-
removeLast(
) → E -
Removes and returns the last element of the queue.…
-
removeWhere(
bool test(E element)) → void -
Removes all elements matched by
testfrom the queue.… -
retainWhere(
bool test(E element)) → void -
Removes all elements not matched by
testfrom the queue.… -
singleWhere(
bool test(E element)) → E -
inherited
Returns the single element that satisfies
test.… -
skip(
int count) → Iterable<E> -
inherited
Returns an Iterable that provides all but the first
countelements.… -
skipWhile(
bool test(E value)) → Iterable<E> -
inherited

testis satisfied.… -
take(
int count) → Iterable<E> -
inherited
Returns a lazy iterable of the
countfirst elements of this iterable.… -
takeWhile(
bool test(E value)) → Iterable<E> -
inherited
Returns a lazy iterable of the leading elements satisfying
test.… -
toList(
{bool growable: true}) → List<E> -
inherited
-
toSet(
) → Set<E> -
inherited
Creates a Set containing the same elements as this iterable.…
-
toString(
) → String -
Returns a string representation of (some of) the elements of
this.… -
