It is indicated in the documentation that addAll has been deprecated in favor of setAll. In the reducer switch/case example, addAll was still being used instead of setAll.

Thanks for the PR @keenanamigos! The file you should edit is here https://github.com/ngrx/platform/blob/master/projects/ngrx.io/content/guide/entity/adapter.md

Those docs are the older versions that will be deleted soon.

Ah, my mistake. Thanks for letting me know! I will make that change.

@keenanamigos will you make one more change, and change the addAll in the list of adapter collections methods to setAll? Thanks!

Thanks a ton @brandonroberts! Sorry for the delay--I can still fix the other piece of documentation re: addAll and setAll if you want?

[brandonroberts]

Sure. No rush
