 * [**`just( )`**](http://reactivex.io/documentation/operators/just.html) — convert an object or several objects into an Observable that emits that object or those objects
 * [**`from( )`**](http://reactivex.io/documentation/operators/from.html) — convert an Iterable, a Future, or an Array into an Observable
 * [**`create( )`**](http://reactivex.io/documentation/operators/create.html) — **advanced use only!** create an Observable from scratch by means of a function, consider `fromEmitter` instead
-* [**`fromEmitter()`**](http://reactivex.io/RxJava/javadoc/rx/Observable.html#fromEmitter(rx.functions.Action1,%20rx.AsyncEmitter.BackpressureMode)) — create safe, backpressure-enabled, unsubscription-supporting Observable via a function and push events.
 * [**`defer( )`**](http://reactivex.io/documentation/operators/defer.html) — do not create the Observable until a Subscriber subscribes; create a fresh Observable on each subscription
 * [**`range( )`**](http://reactivex.io/documentation/operators/range.html) — create an Observable that emits a range of sequential integers
