        Create a Behavior for a persistent actor that is used with Cluster Sharding.

        Any Behavior can be used as a sharded entity actor, but the combination of sharding and persistent actors is very common and therefore this PersistentEntity is provided as convenience.

        It is a EventSourcedBehavior and is implemented in the same way. It selects the persistenceId automatically from the EntityTypeKey and entityId constructor parameters by using EntityTypeKey.persistenceIdFrom.

        Parameters:
        entityTypeKey - (undocumented)
        entityId - (undocumented)
        emptyState - (undocumented)
        commandHandler - (undocumented)
        eventHandler - (undocumented)
        Returns:
        (undocumented)
