Class ReflectiveDynamicAccess

java.lang.Object

akka.actor.DynamicAccess

akka.actor.ReflectiveDynamicAccess

public class ReflectiveDynamicAccess
extends DynamicAccess

This is the default DynamicAccess implementation used by ExtendedActorSystem unless overridden. It uses reflection to turn fully-qualified class names into Class[_] objects and creates instances from there using getDeclaredConstructor() and invoking that. The class loader to be used for all this is determined by the actor system’s class loader by default.

Method Summary

Modifier and Type	Method and Description
java.lang.ClassLoader	classLoader() This is the class loader to be used in those special cases where the other factory method are not applicable (e.g.
<T> scala.util.Try<T>	createInstanceFor(java.lang.Class<?> clazz, scala.collection.immutable.Seq<scala.Tuple2<java.lang.Class<?>,java.lang.Object>> args, scala.reflect.ClassTag<T> evidence$2) Convenience method which given a Class[_] object and a constructor description will create a new instance of that class.
<T> scala.util.Try<T>	createInstanceFor(java.lang.String fqcn, scala.collection.immutable.Seq<scala.Tuple2<java.lang.Class<?>,java.lang.Object>> args, scala.reflect.ClassTag<T> evidence$3) Obtain an object conforming to the type T, which is expected to be instantiated from a class designated by the fully-qualified class name given, where the constructor is selected and invoked according to the args argument.
<T> scala.util.Try<java.lang.Class<? extends T>>	getClassFor(java.lang.String fqcn, scala.reflect.ClassTag<T> evidence$1) Obtain a Class[_] object loaded with the right class loader (i.e.
<T> scala.util.Try<T>	getObjectFor(java.lang.String fqcn, scala.reflect.ClassTag<T> evidence$4) Obtain the Scala &ldquo;object&rdquo; instance for the given fully-qualified class name, if there is one.
