SetBase<E> class

Base implementation of Set.

Base implementation of Set.

This class provides a base implementation of a Set that depends only on the abstract members: add, contains, lookup, remove, iterator, length and toSet.

Some of the methods assume that toSet creates a modifiable set. If using this base class for an unmodifiable set, where toSet should return an unmodifiable set, it's necessary to reimplement retainAll, union, intersection and difference.

Implementations of Set using this base should consider also implementing clear in constant time. The default implementation works by removing every element.

toList Inherited ( {bool growable: true} ) → List<E>
Creates a [List] containing the elements of this [Iterable].
map Inherited ( dynamic f(E element) ) → Iterable
Returns a new lazy [Iterable] with elements that are created by calling f on each element of this Iterable in iteration order.
where Inherited ( bool f(E element) ) → Iterable<E>
Returns a new lazy [Iterable] with all elements that satisfy the predicate [test].
expand Inherited ( Iterable f(E element) ) → Iterable
Expands each element of this [Iterable]into zero or more elements.
forEach Inherited ( void f(E element) ) → void
Applies the function [f] to each element of this collection in iteration order.
reduce Inherited ( 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.
fold Inherited ( initialValue, dynamic combine(previousValue, E element) ) → dynamic
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
every Inherited ( bool f(E element) ) → bool
Checks whether every element of this iterable satisfies [test].
join Inherited ( [String separator = ""] ) → String
Converts each element to a [String] and concatenates the strings.
any Inherited ( bool test(E element) ) → bool
