Does anyone know of an OrderedSet implementation for Squeak somewhere?

Thanks Benoit,

The repository is http://www.squeaksource.com/PharoTaskForces, the package is OrderedSet, and the latest version is OrderedSet-StephaneDucasse.2.mcz

That OrderedSet is not really a set, just a thin wrapper over OrderedCollection, so performance will be surprisingly bad. Squeak has OrderedDictionary which has all the methods a Set needs: #at: anObject put: nil <=> #add: anObject #includesKey: anObject <=> #includes:anObject #keysDo: aBlock <=> #do: aBlock #removeKey: anObject <=> #remove: anObject

Note that removal will take O(size) time. If you need anything better, you have to implement your own set (e.g. a linked hash set. Squeak's LRUCache has a list implementation that can come handy).

That depends on what is meant by 'ordered'. Whenever I wanted an Ordered thing (usually Dictionary, never yet Set) what I really wanted was the order in which the elements (or keys) were added. aBag sortedElements is more like a SortedSet. -cbc

Hi Levente,

I like that idea! Performance is a non-issue for my use case. I don't even have the need to remove elements.

Are there any objections to include OrderedSet as a trivial subclass of OrderedDictionary to Squeak?

I have looked at the list implementation used in LRUCache. I love the terseness of the code. I wonder why it is not called CircularDoublyLinkedList to make it easier to find for other uses.

Hi, there. :-)

Levente, could we please have that OrderedSet as subclass of Set in the Trunk? Pretty please? :-D

I'm not sure if it belongs to the Trunk. It's pretty much a niche collection, though I was thinking the same about OrderedDictionary. If I were to add it to the Trunk, I would implement it as a subclass of Set instead of OrderedDictionary, because OrderedSet doesn't need the methods provided by OrderedDictionary.

...

I have looked at the list implementation used in LRUCache. I love the terseness of the code. I wonder why it is not called CircularDoublyLinkedList to make it easier to find for other uses.

Because I added it to improve LRUCache, and in practice the list nodes are the best if they can be used as a mixin or a stateful trait, but Squeak has neither of those.
