1.  trait ChangeEventHandler[Command, State, ChangeEvent] extends AnyRef

   API May Change: Implement this interface and use it in DurableStateBehavior#withChangeEventHandler to store additional change event when the state is updated.

   API May Change: Implement this interface and use it in DurableStateBehavior#withChangeEventHandler to store additional change event when the state is updated. The event can be used in Projections.

   The updateHandler and deleteHandler are invoked after the ordinary command handler. Be aware of that if the state is mutable and modified by the command handler the previous state parameter of the updateHandler will also include the modification, since it's the same instance. If that is a problem you need to use immutable state and create a new state instance when modifying it in the command handler.

9.  abstract class DurableStateBehaviorWithEnforcedReplies[Command, State] extends DurableStateBehavior[Command, State]

   A DurableStateBehavior that is enforcing that replies to commands are not forgotten.

   A DurableStateBehavior that is enforcing that replies to commands are not forgotten. There will be compilation errors if the returned effect isn't a ReplyEffect, which can be created with Effects().reply, Effects().noReply, EffectBuilder.thenReply, or EffectBuilder.thenNoReply.

10.  trait Effect[State] extends AnyRef

    A command handler returns an Effect directive that defines what state to persist.

    A command handler returns an Effect directive that defines what state to persist.

    Instances of Effect are available through factories DurableStateBehavior.Effect.
