# ListQueue<E> class

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.

## Methods

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`.
addFirst(E value) → void
  Adds `value` at the beginning of the queue.
addLast(E value) → void
  Adds `value` at the end of the queue.
cast<R>() → Queue<R>
  Provides a view of this queue as a queue of `R` instances, if necessary. [...]
clear() → void
  Removes all elements in the queue. The size of the queue becomes zero.
elementAt(int index) → E
forEach(void f(E element)) → void
remove(Object value) → bool
  Remove a single instance of `value` from 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
  Remove all elements matched by `test`. [...]
retainWhere(bool test(E element)) → void
  Remove all elements not matched by `test`. [...]
toList({bool growable: true }) → List<E>
toString() → String
  Returns a string representation of this object.
any(bool test(E element)) → bool
  Checks whether any element of this iterable satisfies `test`. [...]
  inherited
contains(Object element) → bool
  Returns true if the collection contains an element equal to `element`. [...]
  inherited
every(bool test(E element)) → bool
  Checks whether every element of this iterable satisfies `test`. [...]
  inherited
expand<T>(Iterable<T> f(E element)) → Iterable<T>
  Expands each element of this Iterable into zero or more elements. [...]
  inherited
firstWhere(bool test(E element), { E orElse() }) → E
  Returns the first element that satisfies the given predicate `test`. [...]
  inherited
fold<T>(T initialValue, T combine(T previousValue, E element)) → T
  Reduces a collection to a single value by iteratively combining each element of the collection with an existing value [...]
  inherited
followedBy(Iterable<E> other) → Iterable<E>
  Returns the lazy concatentation of this iterable and `other`. [...]
  inherited
join([String separator = "" ]) → String
  Converts each element to a String and concatenates the strings. [...]
  inherited
lastWhere(bool test(E element), { E orElse() }) → E
  Returns the last element that satisfies the given predicate `test`. [...]
  inherited
map<T>(T f(E element)) → Iterable<T>
  Returns a new lazy Iterable with elements that are created by calling `f` on each element of this `Iterable` in iteration order. [...]
  inherited
noSuchMethod(Invocation invocation) → dynamic
  Invoked when a non-existent method or property is accessed. [...]
  inherited
reduce(E combine(E value, E element)) → E
  Reduces a collection to a single value by iteratively combining elements of the collection using the provided function. [...]
  inherited
singleWhere(bool test(E element), { E orElse() }) → E
  Returns the single element that satisfies `test`. [...]
  inherited
skip(int count) → Iterable<E>
  Returns an Iterable that provides all but the first `count` elements. [...]
  inherited
skipWhile(bool test(E element)) → Iterable<E>
  Returns an `Iterable` that skips leading elements while `test` is satisfied. [...]
  inherited
take(int count) → Iterable<E>
  Returns a lazy iterable of the `count` first elements of this iterable. [...]
  inherited
takeWhile(bool test(E element)) → Iterable<E>
  Returns a lazy iterable of the leading elements satisfying `test`. [...]
  inherited
toSet() → Set<E>
  Creates a Set containing the same elements as this iterable. [...]
  inherited
where(bool test(E element)) → Iterable<E>
  Returns a new lazy Iterable with all elements that satisfy the predicate `test`. [...]
  inherited
whereType<T>() → Iterable<T>
  Returns a new lazy Iterable with all elements that have type `T`. [...]
  inherited

## Operators
