Java API: compatible with lambda expressions
Actor base class that should be extended to create Java actors that use lambdas.
Example:
public class MyActorForJavaDoc extends AbstractActor{ @Override public Receive createReceive() { return receiveBuilder() .match(Double.class, d -> { sender().tell(d.isNaN() ? 0 : d, self()); }) .match(Integer.class, i -> { sender().tell(i * 10, self()); }) .match(String.class, s -> s.startsWith("foo"), s -> { sender().tell(s.toUpperCase(), self()); }) .build(); } }

Is called when a message isn't handled by the current behavior of the actor by default it fails with either a akka.actor.DeathPactException (in case of an unhandled akka.actor.Terminated message) or publishes an akka.actor.UnhandledMessage to the actor's system's akka.event.EventStream
