ordered_set #

Build Status Coverage Status

A simple implementation for an ordered set for Dart.

It accepts a compare function that compares items for their priority.

Unlike Dart's SplayTreeSet, it allows for several different elements with the same priority to be added.

It also implements Iterable, so you can iterate it in O(n).

Usage #

A simple usage example:

  import 'package:ordered_set/ordered_set.dart';

  main() {
    OrderedSet<int> items = OrderedSet();
    items.add(2);
    items.add(1);
    print(items.toList()); // [1, 2]
  }

Comparing #

In order to assist the creation of OrderedSet's, there is a Comparing class to easily create Comparables:

  // sort by name length
  final people = OrderedSet<Person>(Comparing.on((p) => p.name.length));

  // sort by name desc
  final people = OrderedSet<Person>(Comparing.reverse(Comparing.on((p) => p.name)));

  // sort by role and then by name
  final people = OrderedSet<Person>(Comparing.join([(p) => p.role, (p) => p.name]));
