Hi itsme, I see that you have been asked already but, could you please give us a name we can use besides itsme213?
You can use SortedCollection. SortedCollection new sortBlock: [:a :b | a index < b index]. This provides ordering but does not eliminate duplicates. That can be accomplished pretty simply by checking for uniqueness before adding to the collection. You could also use a Dictionary, if your data is not too large. aDict := Dictionary new. aDict at: anObject index ifAbsentPut: anObject. This provides both sorting and set like operations (again by checking for uniqueness before adding). Otherwise just use OrderedCollection and manage order and uniqueness manually. The class has all the methods you need to do so. Happy Coding!
