Public Member Functions
	DS ()
	default constructors
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)
	Returns full vector of observed data=[output, input].
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	step ()
	Moves from to , i.e. perfroms the actions and reads response of the system.
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.

Detailed Description

Abstract class for discrete-time sources of data.

The class abstracts operations of:

• data aquisition,
• data-preprocessing, such as scaling of data,
• data resampling from the task of estimation and control. Moreover, for controlled systems, it is able to receive the desired control action and perform it in the next step. (Or as soon as possible).

The DataSource has three main data interaction structures:

• input, ,
• output ,
• data, a collection of all inputs and outputs and possibly some internal variables too.
