An instance method is a method that's available on a particular instance of a class, after the instance has been instantiated: MyClass *instance = [MyClass new]; [instance someInstanceMethod]; Here's how you define one: @interface MyClass : NSObject - (void)someInstanceMethod; // "-&qu...
Detailed instructions on getting ibm-midrange set up or installed.
Collection initialization syntax can be used when instantiating any class which implements IEnumerable and has a method named Add which takes a single parameter. In previous versions, this Add method had to be an instance method on the class being initialized. In C#6, it can also be an extension me...
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...
Life-cycle hooks are also exposed as DSL elements, where later invocations of the methods shown below will replace the contents of the respective hooks: val a = actor(new Act { whenStarting { testActor ! "started" } whenStopping { testActor ! "stopped" } }) The above i...
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...
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...
