Pointcuts

#Here are our pointcuts

Actor creation pointcuts

Pointcut for the actorOf(..) methods in ActorCell and ActorSystem, extracting the Props being used

    static pointcut anyActorOf(Props props) : (execution(* akka.actor.ActorSystem.actorOf(..)) ||
            execution(* akka.actor.ActorCell.actorOf(..))) && args(props);

Pointcut for the actorOf(..) methods in ActorCell and ActorSystem where actor is named on creation, extracting the Props being used, and the String name of the actor

    static pointcut namedActorOf(Props props, String actorName) :
            (execution(* akka.actor.ActorSystem.actorOf(..)) ||
                execution(* akka.actor.ActorCell.actorOf(..))) && args(props, actorName);

Actor death pointcuts

Pointcut for ActorCell.stop(actor), extracting the ActorRef of the actor being stopped

    static pointcut actorCellStop(ActorRef actor) : execution(* akka.actor.ActorCell.stop(..)) && args(actor);

Pointcut for ActorCell.stop(), extracting the ActorCell whose stop() method is being executed

    static pointcut actorCellInternalStop(ActorCell actorCell) : target(actorCell) && execution(* akka.actor.ActorCell.stop());

Receive message pointcuts

Pointcut for ActorCell.receiveMessage(msg), extracting the ActorCell receiving the message, and the Object message being received

    static pointcut actorCellReceiveMessage(ActorCell actorCell, Object msg) : target(actorCell) &&
            call(* akka.actor.ActorCell.receiveMessage(..)) && args(msg);

Failure pointcuts

Pointcut for ActorCell.handleInvokeFailure(_, failure), extracting the ActorCell handling the failure, and the Throwable cause of the failure

    static pointcut actorCellHandleInvokeFailure(ActorCell actorCell, Throwable failure) : target(actorCell) &&
            execution(* akka.actor.ActorCell.handleInvokeFailure(..)) && args(*, failure);

EventStream pointcuts

Pointcut for the EventStream.publish(event) method, extracting just the Object event

    static pointcut eventStreamPublish(Object event) :
            execution(* akka.event.EventStream.publish(..)) && args(event);
