2.x: Observable missing or incorrect images (tracking issue)

[akarnokd]

• Observable.singleOrError(): There is no default value and an empty source should result in an error.
• Observable.combineLatestDelayError(ObservableSource[], Function): missing diagram
• Observable.combineLatestDelayError(Function, int, ObservableSource...): missing diagram

• Observable.doOnError: indicate that the events pass through and the star is execute before the onError to downstream
• Observable.doOnLifecycle: change unsubscribe to dispose
• Observable.doOnNext: indicate that the events pass through and the star is execute before the onNext to downstream
• Observable.doOnTerminate: indicate that the events pass through and the star is execute before the onError or onComplete to downstream
• Observable.elementAt(long): example of empty source
• Observable.elementAt(long, T): example of empty source
• Observable.elementAtOrError(long): example of empty source
• Observable.firstElement: diagram is stretched
• Observable.firstOrError: the operator name in the box
• Observable.flatMap(Function, boolean, int): missing diagram
• Observable.flatMap(Function, boolean, int, int): missing diagram
• Observable.flatMap(Function, Function, Callable, int): missing diagram

• Observable.flatMapCompletable(): missing diagram
• Observable.flatMapIterable(Function): diagram looks stretched
• Observable.forEach(): missing diagram
• Observable.forEachWhile(): missing diagram
• Observable.hide(): missing diagram - not sure how to represent this
• Observable.lastOrError(): operator name in the box, error case example.
• Observable.onErrorReturn(): indicate that the value is the result of a function call
• Observable.onErrorReturnItem(): operator name in the box
• Observable.onTerminateDetach: missing diagram
• Observable.publish(Function): there is no connect call, may need extensive redrawing
• Observable.reduceWith(): operator name in the box
• Observable.repeat() + overloads: indicate fresh subscriptions happen, not caching
• Observable.repeatUntil: operator name in the box, indicate fresh subscriptions
• Observable.replay() + overloads: remove publish
• Observable.replay(Function, ...) overloads: may need extensive redrawing
• Observable.retry(long) indicate limited retry effect
• Observable.retry(Predicate) indicate predicate effect, show it in the box
• Observable.retry(long, Predicate) indicate predicate, show them in the box
• Observable.retryUntil: operator name in the box, show BooleanSupplier
• Observable.share(): fix labels with unsubscribe
• Observable.singleElement: example with empty source
• Observable.sorted: missing diagram
• Observable.startWith(T): have a single item as start value
• Observable.startWithArray(T...): operator name
• Observable.subscribe + overloads: missing diagram
• Observable.switchMapSingle: inner sources should have 1 item.
• Observable.switchMapDelayError + indicate the error case
• Observable.toList(Callable): indicate the custom collection somehow?
• Observable.toFlowable(): missing diagram
• Observable.unsubscribeOn(): missing diagram
• Observable.zipWith() + overloads: the diagram is in line with some text and appears pushed to the right
• Observable.test(): missing diagram, can this be represented as diagram?

PRs welcome. The most easy ones are those that require alignment/displayed size corrections.

Hi David, I'd love to help, what would I use to edit the diagrams?

[akarnokd]

If you are on Mac and you own OmniGraffle, there is a file for all traditional diagrams:
ReactiveX/reactivex.github.io#223

I'm using Excel 2007+ on Windows to draw the newer diagrams and have a file here you can use as basis for newer diagrams. I don't know if the open office variants could open this file or not, Google's viewer certainly doesn't show the drawings.

I suppose as a last resort you can draw in the open-office variants as well and post the PNGs in this issue. Uploading it requires access to the wiki git of RxJava. The target rendering is 640 pixels wide and as long as it needs to be.

The process is as follows:

• Draw diagram(s)
• Upload to git
• Modify Javadoc locally to point to the raw usercontent
• Verify and fix alignment/stretching
• Commit PR to RxJava itself

Is it switchMapSingle need a new diagram too? SingleResource can't emit 2 items.

[akarnokd]

Yes. I'll add it to the list above.

Another option is to use free open-source multi-platform Inkscape. Templates here:
