* Receive class that wraps PartialFunction, to avoid
scary scala types
* move AbstractActorContext to AbstractActor.ActorContext
* converting docs, many, many UntypedActor
* removing UntypedActor docs
* add unit test for ReceiveBuilder
* MiMa filters
* consistent use of getContext(), self(), sender()
* rename cross references
* migration guide
* skip samples for now
* improve match type safetyi, add matchUnchecked
* the `? extends P` caused code like this to compile:
`match(String.class, (Integer i) -> {})`
* added matchUnchecked, since it can still be useful (um, convenient)
to be able to do:
`matchUnchecked(List.class, (List<String> list) -> {})`
* eleminate some scala.Option
* preRestart
* findChild
* ActorIdentity.getActorRef

Java 8 and Scala Compatibility
|
|
==============================
|
|
|
|
Starting with Akka 2.4.2 we have begun to introduce Java 8 types (most
|
|
prominently ``java.util.concurrent.CompletionStage`` and
|
|
``java.util.Optional``) where that was possible without breaking binary or
|
|
source compatibility. Where this was not possible (for example in the return
|
|
type of ``ActorSystem.terminate()``) please refer to the
|
|
``scala-java8-compat`` library that allows easy conversion between the Scala
|
|
and Java counterparts. The artifact can be included in Maven builds using::
|
|
|
|
<dependency>
|
|
<groupId>org.scala-lang.modules</groupId>
|
|
<artifactId>scala-java8-compat_2.11</artifactId>
|
|
<version>0.7.0</version>
|
|
</dependency>

We will only be able to seamlessly integrate all functional interfaces once
|
|
we can rely on Scala 2.12 to provide full interoperability—this will mean that
|
|
Scala users can directly implement Java Functional Interfaces using lambda syntax
|
|
as well as that Java users can directly implement Scala functions using lambda
|
|
syntax.
