Akka/Scala example source code file (RouteTransformer.java)

This example Akka source code file (RouteTransformer.java) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Akka and Scala source code examples by using tags.

All credit for the original source code belongs to akka.io; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

Akka tags/keywords

actor, actorref, akka, camel, camelmessage, dispatch, mapper, override, routetransformer, string, untypedactor

The RouteTransformer.java Akka example source code

package sample.camel.route;

import akka.actor.ActorRef;
import akka.actor.UntypedActor;
import akka.camel.CamelMessage;
import akka.dispatch.Mapper;

public class RouteTransformer extends UntypedActor {
  private ActorRef producer;

  public RouteTransformer(ActorRef producer) {
    this.producer = producer;
  }

  public void onReceive(Object message) {
    if (message instanceof CamelMessage) {
      // example: transform message body "foo" to "- foo -" and forward result
      // to producer
      CamelMessage camelMessage = (CamelMessage) message;
      CamelMessage transformedMessage = camelMessage.mapBody(new Mapper<String, String>() {
        @Override
        public String apply(String body) {
          return String.format("- %s -", body);
        }
      });
      producer.forward(transformedMessage, getContext());
    } else
      unhandled(message);
  }
}
