Implementation issue. Set is based on dictionary and thus a waste of memory. We want low memory footprint and fast access (adding is only down when loading a model). Array is the best solution, occasionally adding element with copyWith:. But we should make sure that no duplicates are added, and raise error if someone tries so! I guess that test is missing.

Something related I would like to have a flatCollect with which I do not have to do asSet at the end. So a kind of flatUniqueCollect that still return an UniqueOrderedCollection instead of a set

#collectAsSet: just returns the set of the collect, while Stef would want a #collectUnionAsSet: . But, if you do the UniqueOrderedCollection :), it should work, no?

Please have a look at CodeFooDevelopment >> CodeFoo >> Collection >> enumerating There is #collectUnion: #flattern #gather: #recurisveCollect: that all use a collection of the same species as the receiver, and #collectAsSet: #transitiveClosure: that use a Set for any collection. If your need is not covered by that, please feel free to add your own enumerators there. cheers, AA On 23 Nov 2007, at 9:00 , Stéphane Ducasse wrote: >> #collectAsSet: just returns the set of the collect, while Stef would >> want a #collectUnionAsSet: .

SmartSet represents an unordered collection of elements that are not duplicated. SmartSet can operate in two modes - self optimizeGrowth, whereas its values are backed up by a conventional Set - self optimizeMemory, whereas its values are backed up by an Array Other than Set, an attempt to add a duplicate element signals an Error.

What is the difference between UniqueOrderedCollection and SmartSet (except for keyed access)? I add #unsafeAdd: / #unsafeAddAll: / #assertInvariant to SmartSet. cheers, AA On 23 Nov 2007, at 9:02 , Stéphane Ducasse wrote: > fun we should have also UniqueOrderedCollection (should be a couple > of methods) > BTW UniqueOrderedCollection could also have a fastAdd: (one that does > not check uniqueness) if > you need large collection and by contract the clients knows that it > is responsible of not putting > duplicated stuff in there. > > Stef > > > On 22 nov. 07, at 23:46, Adrian Kuhn wrote: > >> SmartSet represents an unordered collection of elements that are not >> duplicated. >> >> SmartSet can operate in two modes >> >> - self optimizeGrowth, whereas its values are backed up by a >> conventional Set >> - self optimizeMemory, whereas its values are backed up by an Array >> >> Other than Set, an attempt to add a duplicate element signals an >> Error. >> >> AA >> >> >> >> On 22 Nov 2007, at 21:32 , Stéphane Ducasse wrote: >> >>> Does it make sense to implement and use UniqueOrderedCollection or >>> UniqueArray? >>> >> >> _______________________________________________ >> Moose-dev mailing list >> Moose-dev(a)iam.unibe.ch >> https://www.iam.unibe.ch/mailman/listinfo/moose-dev >> > > > _______________________________________________ > Moose-dev mailing list > Moose-dev(a)iam.unibe.ch > https://www.iam.unibe.ch/mailman/listinfo/moose-dev _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
