Re: [Pharo-users] Why can't a Bag answer as a dictionary?

Re: [Pharo-users] Why can't a Bag answer as a dictionary?

To me, a bag is first and foremost a multiset. Yes, it's a collection, but it's not *just* a collection. It's a very specific kind of collection with a very salient "characteristic function". In my own Smalltalk library, #asDictionary isn't even *defined* on things that are not dictionaries or

Re: [Pharo-users] Why can't a Bag answer as a dictionary?

I still am tempted to make asDictionary work - because the the moment you get a #key , DNU error - which is definitely not right. So should Bag asDictionary give you a reasonable dictionary, or should it throw a proper exception - something like: DomainError signal: ‘#asDictionary not

And when asking the object: #(1 2 4 5 6 7 2 1 4 3) asBag isDictionary we get false. So, not, not a dictionary. I still have been using #valuesAndCounts to get the dictionary out of a bag on several occasions. And is useful indeed. #(1 2 4 5 6 7 2 1 4 3) asBag occurrencesOf: 2 and #(1 2 4 5

Re: [Pharo-users] Why can't a Bag answer as a dictionary?

I was just explaining how it is now, what I think the rationale is behind it. I understand #asDictionary as working on a collection of pairs/associations (because it basically goes to #withAll:). A bag is just a collection that is optimised for many duplicates, the fact that you have values

Re: [Pharo-users] Why can't a Bag answer as a dictionary?

As Richard said - as a bag is relationship between keys and frequencies, I would expect it to be able to convert to a dictionary. It displays in an inspector just like a Dictionary - which is why I figured I could convert to pass it back to the exercise that was written with Dictionaries in

Re: [Pharo-users] Why can't a Bag answer as a dictionary?

Doubtless the original poster expected aBag asDictionary to answer a dictionary mapping the (distinct) elements of the bag to their counts. Mathematically, a bag can usefully be seen as a partial function from a set U to the positive integers, and a dictionary with U keys and positive integer

I was surprised to find that a Bag can’t convert to a dictionary - e.g. Bag new addAll: 'aacddd’; asDictionary Gives an error - Dnu #key It looks to me like Bag is inheriting a bad version of #associationsDo: and instead could simply forward it to #doWithOccurences:
