To create simple actors without creating a new class, you can use: import akka.actor.ActorDSL._ import akka.actor.ActorSystem implicit val system = ActorSystem("demo") val a = actor(new Act { become { case "hello" ⇒ sender() ! "hi" } })

The two possible ways of issuing a context.become (replacing or adding the new behavior) are offered separately to enable a clutter-free notation of nested receives: val a = actor(new Act { become { // this will replace the initial (empty) behavior case "info" ⇒ sender() ! "A...

It is also possible to create nested actors, i.e. grand-children, like this: // here we pass in the ActorRefFactory explicitly as an example val a = actor(system, "fred")(new Act { val b = actor("barney")(new Act { whenStarting { context.parent ! ("hello from &quot...

It is also possible to assign a supervision strategy to these actors with the following: superviseWith(OneForOneStrategy() { case e: Exception if e.getMessage == "hello" ⇒ Stop case _: Exception ⇒ Resume })

Last but not least there is a little bit of convenience magic built-in, which detects if the runtime class of the statically given actor subtype extends the RequiresMessageQueue trait via the Stash trait (this is a complicated way of saying that new Act with Stash would not work because its runtime ...

Angular supports three types of expressions in the ng-class directive. 1. String <span ng-class="MyClass">Sample Text</span> Specifying an expression that evaluates to a string tells Angular to treat it as a $scope variable. Angular will check the $scope and look for a va...

The goal with using anonymous structs is to decode only the information we care about without littering our app with types that are used only in a single function. jsonBlob := []byte(` { "_total": 1, "_links": { "self": "https://api.twitch.tv/k...
