Find out the sender when a message is received

[Dulaj Viduranga]

Hi,

I have an application where a message receiver needs to find out who the sender is and do the processing accordingly. Is it possible to check this inside a behavior lambda?

Thanks.

Yes: self->current_sender().

You can have a look at the Dining Philosophers example to see it in use: https://github.com/actor-framework/actor-framework/blob/master/examples/dynamic_behavior/dining_philosophers.cpp.

Thank you Dominik. This is helpful. Is there a way to compare the strong_actor_ptr I get from this against a typed_actor type (without having the handle to the specific actor) to check if the message is sent from a specific type of actor?
