A specialized double-linked list of elements that extends LinkedListEntry.

This is not a generic data structure. It only accepts elements that extend the LinkedListEntry class. See the Queue implementations for generic collections that allow constant time adding and removing at the ends.

This is not a List implementation. Despite its name, this class does not implement the List interface. It does not allow constant time lookup by index.

Because the elements themselves contain the links of this linked list, each element can be in only one list at a time. To add an element to another list, it must first be removed from its current list (if any).

In return, each element knows its own place in the linked list, as well as which list it is in. This allows constant time LinkedListEntry.addAfter, LinkedListEntry.addBefore and LinkedListEntry.unlink operations when all you have is the element.

A LinkedList also allows constant time adding and removing at either end, and a constant time length getter.

Constructors

LinkedList()

Construct a new empty linked list.

Methods

add(E entry) → void

Add entry to the end of the linked list.

addAll(Iterable<E> entries) → void

Add entries to the end of the linked list.

addFirst(E entry) → void

Add entry to the beginning of the linked list.

any(bool f(E element)) → bool
inherited

Checks whether any element of this iterable satisfies test.

clear() → void

Remove all elements from this linked list.

contains(Object element) → bool
inherited

Returns true if the collection contains an element equal to element.

elementAt(int index) → E
inherited

Returns the indexth element.

every(bool f(E element)) → bool
inherited

Checks whether every element of this iterable satisfies test.

expand(Iterable f(E element)) → Iterable
inherited

Expands each element of this Iterableinto zero or more elements.

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

Returns the first element that satisfies the given predicate 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 action(E entry)) → void

Call action with each entry in this linked list.

join([String separator = ""]) → String
inherited

Converts each element to a String and concatenates the strings.

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 f on each element of this Iterable in 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(E entry) → bool

Remove entry from the linked list.

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 count elements.

skipWhile(bool test(E value)) → Iterable<E>
inherited

Returns an Iterable that skips leading elements while test is satisfied.

take(int count) → 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.

toList({bool growable: true}) → List<E>
inherited

Creates a List containing the elements of this Iterable.

toSet() → Set<E>
inherited

Creates a Set containing the same elements as this iterable.

toString() → String
inherited

Returns a string representation of (some of) the elements of this.

where(bool f(E element)) → Iterable<E>
inherited

Returns a new lazy Iterable with all elements that satisfy the predicate test.
