Resolves #6179

Added JavaDocs describing the regular and canceled/disposed behavior for

  • Observable.fromCallable()
  • Single.fromCallable()
  • Maybe.fromAction()
  • Completable.fromCallable()
  • Completable.fromAction()
  • Flowable.fromCallable()

Did not alter Maybe.fromCallable() because the existing JavaDoc appears to be adequate.

Small adjustments would be great. Could you also update Flowable.fromCallable?

"downstream has disposed this" as only Flowables have cancel.

I noticed that there's quite a bit more of the "cancellation" language in the other areas.
For example:

  • Single.java:833 ...and all other source {@code SingleSource}s are cancelled.
  • Completable.java:1588 * @param onFinally the action called when this Completable terminates or gets cancelled

Should this be added to #4535?

Post a separate PR for those.

Should I create a separate issue as well?

Also, is there anything else you need from me to get this PR merged (unsure of the process at this point)?

No need to open an issue for that.

We are waiting for another approval and this will be merged.
