Public Member Functions
void	step ()
	Moves from to , i.e. perfroms the actions and reads response of the system.
void	getdata (vec &dt_out)
	Returns full vector of observed data=[output, input].
void	write (const vec &ut0)
void	from_setting (const Setting &set)
void	validate ()
	This method TODO.
virtual int	max_length ()
	Returns maximum number of provided data, by default it is set to maximum allowed length, shorter DS should overload this method! See, MemDS.max_length().
virtual void	getdata (vec &dt, const ivec &indeces)
	Returns data records at indeces.
virtual void	write (vec &ut)
	Accepts action variable and schedule it for application.
virtual void	write (vec &ut, const ivec &indeces)
	Accepts action variables at specific indeces.
virtual void	log_add (logger &L)
	Register DS for logging into logger L.
virtual void	logit (logger &L)
	Register DS for logging into logger L.
virtual const RV &	_drv () const
	access function
const RV &	_urv () const
	access function
const RV &	_yrv () const
	access function
virtual void	set_drv (const RV &yrv, const RV &urv)
	set random variables
virtual string	to_string ()
	This method returns a basic info about the current instance.
virtual void	to_setting (Setting &set) const
	This method save all the instance properties into the Setting structure.

                mpdf = {class="mpdf_offspring", ...};  // mpdf to simulate
                --- optional ---
                init_rv = {class="RV",names=...};      // define what rv to initialize - typically delayed values!
                init_values = [...];                   // vector of initial values corresponding to init_rv

If init_rv is not given, init_values are set to zero.

Reimplemented from bdm::root.
