========

Either is a value of one of two possible types.

Inspired by Jeffrey van Gogh's [discussion][jeffrey] with the Rx.Net users, RxEither is a port of Scala's [Either][either] for the [RxJava][rx] world.

Usage

-----

* **Progress reporting**

  ```java

  public class ProgressExample {

       public static void main(String[] args) {

              PublishSubject progress = PublishSubject.create();

              Observable results = Observable.fromCallable(() -> {

                  progress.onNext(0);

                  TimeUnit.SECONDS.sleep(1);

                  progress.onNext(100);

                  return "Hello, world!";

              }).subscribeOn(Schedulers.io());

              Observable> either = RxEither.from(progress, results).share();

              RxEither.filterLeft(either).subscribe(System.out::println);

              RxEither.filterRight(either).toBlocking().subscribe(System.out::println);

          }

  }

  ```

  Prints:

  ```

  0

  100

  Hello, world!

  ```

* **Switch**

  ```java

  public class SwitchActionExample {

      public static void main(String[] args) {

          System.out.println("Type Either a string or an Int: ");

          String in = "";

          Either either;

          try (BufferedReader reader = new BufferedReader(new InputStreamReader(System.in))) {

              in = reader.readLine();

              either = Either.right(Integer.parseInt(in));

          } catch (NumberFormatException | IOException e) {

              either = Either.left(in);

          }

          either.fold(

              s -> {

                  System.out.println("You passed me the String: " + s);

              },

              x -> {

                  System.out.println(

                          "You passed me the Int: " + x

                                  + ", which I will increment. " + x + " + 1 = "

                                  + (x + 1));

              });

      }

  }

  ```

  Prints:

  ```

  Type Either a string or an Int:

  1

  You passed me the Int: 1, which I will increment. 1 + 1 = 2

  ```
