Hi Subhajith @meBaga,

I got a chance to look at your example (Drama.lvproj).  That's attractive example as it shows up as artificial intelligence example where computer responds to our messages.  🙂  Thanks for that.

I was looking for the abstract messaging (of AF messages) in that example.  Is that example implemented with AF abstracted messages? 

I assumed abstracted messages should be implemented with inherited classes from AF-message class.  Am I missing something here?

I thought that the message should be dynamically dispatched as like below.

There is no inheritance of message class

Thanks,

Ajay.

Hello Ajay, 

Sorry for late reply, correct me if I have misunderstood your doubt.

In this case the Actor messages are not inherited from the Actor class not from each other also. Each messages are inherited from the Actor Message class. The Root Actor is used to launch the two nested actors and each actor has their own message.

As the property of the Root actor and the nested actors are not same, they must not be inherited. These actors and messages are independent of each other making low coupling between them.

Also for your reference ,

In OOP Scenario, when a class is inherited from another class, the relationship is called "Parent Class - Child Class"

In Actor Framework, when an actor launch another actor, the relationship is called "Root Actor - Nested Actor"
