public abstract class AbstractActor
extends java.lang.Object
implements Actor

Java API: compatible with lambda expressions

Actor base class that should be extended to create Java actors that use lambdas.

Example:

 public class MyActor extends AbstractActor {
   int count = 0;

   public MyActor() {
     receive(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()
     );
   }
 }
 

This is an EXPERIMENTAL feature and is subject to change until it has received more real world testing.
