Class Serializer

A Serializer represents a bimap between an object and an array of bytes representing that object.

Serializers are loaded using reflection during ActorSystem start-up, where two constructors are tried in order:

  • taking exactly one argument of type ExtendedActorSystem; this should be the preferred one because all reflective loading of classes during deserialization should use ExtendedActorSystem.dynamicAccess (see [[akka.actor.DynamicAccess]]), and
  • without arguments, which is only an option if the serializer does not load classes using reflection.

Be sure to always use the PropertyManager for loading classes! This is necessary to avoid strange match errors and inequalities which arise from different class loaders loading the same class.
