I have a parent Actor class called MainActor and a child actor called
HelloLocalActor
----------------------------------------------------------------------------------------------------
public class MainActor extends UntypedActor{
ActorRef actorRef ;
@Override
public void onReceive( Object message ) throws Exception
{
if( message instanceof MyMessage )
{
actorRef = getSender();
System.out.println("In Main Actor");
getContext().actorOf(Props.create(HelloLocalActor.class),"HelloLocalActor").tell(message,
self());
}
else if(message instanceof MyLocalMessage){
System.out.println("Inside Main Actor");
actorRef.tell(message, self());
}
else
{
unhandled( message );
}
}
}
----------------------------------------------------------------------------------------------------------------------
public class HelloLocalActor extends UntypedActor
{
@Override
public void onReceive( Object message ) throws Exception
{
if( message instanceof MyMessage )
{
System.out.println("Inside Hello Local Actor..");
MyMessage myMessage = ( MyMessage )message;
MyLocalMessage myLocalMessage = new MyLocalMessage();
myLocalMessage.setMessage( "Local Hello, " +
myMessage.getMessage() );
getSender().tell( myLocalMessage, getSelf() );
getContext().stop(getSelf());
}
else
{
unhandled( message );
}
}
}
--------------------------------------------------------------------------------------------------------
In the HelloLocalActor's onReceive() method, I am calling the
"getContext().stop(getSelf());" method.
If I don't do so, I sometimes get the "InvalidActorNameException: actor
name [HelloLocalActor] is not unique!" error.
My questions are ?
1) Is it okay to call "getContext().stop(getSelf());" method ?
2) Will it have any adverse effect on the application?
3) It really necessary to call the stop() after the child worker has
stopped execution?
