      • apply

        public <Command,​State> DurableStateBehavior<Command,​State> apply​(PersistenceId persistenceId,
                                                                             State emptyState,

        Create a Behavior for a persistent actor with durable storage of its state.

        Parameters:
        persistenceId - stable unique identifier for the DurableStateBehavior
        emptyState - the intial state for the entity before any state has been stored
        commandHandler - map commands to effects e.g. persisting state, replying to commands

      • withEnforcedReplies

        public <Command,​State> DurableStateBehavior<Command,​State> withEnforcedReplies​(PersistenceId persistenceId,
                                                                                           State emptyState,

        Create a Behavior for a persistent actor that is enforcing that replies to commands are not forgotten. Then there will be compilation errors if the returned effect isn't a ReplyEffect, which can be created with Effect.reply, Effect.noReply, EffectBuilder.thenReply, or EffectBuilder.thenNoReply.

      • lastSequenceNumber

        public long lastSequenceNumber​(ActorContext<?> context)
        The last sequence number that was persisted, can only be called from inside the handlers of a DurableStateBehavior
