Which scala mutable list to use?


This is a followup question to No Scala mutable list

I want to use a mutable list in Scala. I can chose from

Which is nice, but what is the "standard", recommended, idiomatic scala way? I just want to use a list that I can add things to on the back.

In my case, I am using a HashMap, where the "lists" (I am meaning it in general sense) will be on value side. Then, I am reading something from a file and for every line, I want to find the right list in the hashmap and append the value to the list.


Solution

  • The documentation's Concrete Mutable Collection Classes page (or the one for 2.12) has an overview of mutable list classes, including explanations on when to use which one.
