ListQueue<E> class

List based Queue.

List based Queue.

Keeps a cyclic buffer of elements, and grows to a larger buffer when it fills up. This guarantees constant time peek and remove operations, and amortized constant time add operations.

The structure is efficient for any queue or stack usage.

Instance Methods

forEach(void action(E element)) → void
Applies the function [f] to each element of this collection in iteration order.
elementAt(int index) → E
Returns the [index]th element.
toList({bool growable: true}) → List<E>
Creates a [List] containing the elements of this [Iterable].
add(E value) → void
Adds [value] at the end of the queue.
addAll(Iterable<E> elements) → void
Adds all elements of [iterable] at the end of the queue. The length of the queue is extended by the length of [iterable].
remove(Object value) → bool
Remove a single instance of [value] from the queue.
removeWhere(bool test(E element)) → void
Remove all elements matched by test.
retainWhere(bool test(E element)) → void
Remove all elements not matched by test.
clear() → void
Removes all elements in the queue. The size of the queue becomes zero.
toString() → String
Returns a string representation of (some of) the elements of this.
addLast(E value) → void
Adds [value] at the end of the queue.
addFirst(E value) → void
Adds [value] at the beginning of the queue.
removeFirst() → E
Removes and returns the first element of this queue.
removeLast() → E
Removes and returns the last element of the queue.
map(dynamic f(E element)) → Iterable Inherited
Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order.
where(bool f(E element)) → Iterable<E> Inherited
Returns a new lazy Iterable with all elements that satisfy the predicate test.
expand(Iterable f(E element)) → Iterable Inherited
Expands each element of this Iterableinto zero or more elements.
contains(Object element) → bool Inherited
Returns true if the collection contains an element equal to element.
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.
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
every(bool f(E element)) → bool Inherited
Checks whether every element of this iterable satisfies test.
join([String separator = ""]) → String Inherited
Converts each element to a String and concatenates the strings.
any(bool f(E element)) → bool Inherited
Checks whether any element of this iterable satisfies test.
toSet() → Set<E> Inherited
Creates a Set containing the same elements as this iterable.
take(int n) → Iterable<E> Inherited
Returns a lazy iterable of the count first elements of this iterable.
takeWhile(bool test(E value)) → Iterable<E> Inherited
Returns a lazy iterable of the leading elements satisfying test.
skip(int n) → Iterable<E> Inherited
Returns an Iterable that provides all but the first count elements.
skipWhile(bool test(E value)) → Iterable<E> Inherited
Returns an Iterable that skips leading elements while test is satisfied.
firstWhere(bool test(E element), {E orElse()}) → E Inherited
Returns the first element that satisfies the given predicate test.
lastWhere(bool test(E element), {E orElse()}) → E Inherited
Returns the last element that satisfies the given predicate test.
singleWhere(bool test(E element)) → E Inherited
Returns the single element that satisfies test.
take(int n) → Iterable<E> Inherited
