Design update functions and their naming convention

Question

I am writing updaters for my component-store.

The situation is as follows:

1. I have an Array Of models named processingStatuses.
2. Sometimes t I have to update all of them.
3. Sometimes I just want to update one of them.

I am wondering which design is better.

1. Separate this into 2 functions.

readonly updateOneProcessingStatus = this.updater(...);
readonly updateProcessingStatuses = this.updater(...);

2. Always pass the whole array to the updater. When I want to update one, I get the array from the old state, modify it and then pass it to the updateProcessingStatuses().

readonly updateProcessingStatuses = this.updater(...);

And I also want to know if my naming is acceptable or not. (e.g. plural)

Thanks!

In my view, it is better to create two functions update() and updateRange(). By doing this your API will be cleaner and when new developer will try to update, then she/he will have clear understanding what method should be used.

In addition, it can be seen that this approach is used in Entity Framework. UpdateRange() and just simple Update() method
