RxScala v0.23.0 Release Notes

Release Date: 2014-12-04 // over 9 years ago

  • 🚀 This release upgrades RxJava from 1.0.0-rc.5 to 1.0.2 along with some enhancements and bug fixes.

    💥 Breaking Changes

    • 💥 Breaking changes in RxJava. Read the RxJava Release Notes for more information.
    • ✂ Remove Observable.compose and JavaConversions.toJavaTransformer because Scala has extension methods. It's much nicer than compose.
    • Rewrite toMap in an idiomatic Scala way.
      • Add def to[M[_, _], K, V](keySelector: T => K, valueSelector: T => V)(implicit cbf: CanBuildFrom[Nothing, (K, V), M[K, V]]): Observable[M[K, V]].
      • Remove def toMap[K, V] (keySelector: T => K, valueSelector: T => V, mapFactory: () => Map[K, V]): Observable[Map[K, V]]. In Scala, we can use CanBuildFrom to build a Map instead of mapFactory.
    • Rewrite toMultimap in an idiomatic Scala way.
      • Change the return type from Observable[scala.collection.Map[K, Seq[T]]] to Observable[mutable.MultiMap[K, V]].
      • Change the method name toMultimap to toMultiMap to make it consistent to the return type.
      • Remove toMultimap(keySelector, valueSelector, mapFactory, bufferFactory). You can override MultiMap.makeSet to create your custom bufferFactory Instead.

    👀 See RxScalaDemo.toMapExample ✅ and RxScalaDemo.toMultiMapExample for examples of new toMap and toMultiMap.
