## Public Member Functions
void | getdata (vec &dt)
| Returns full vector of observed data.
void | getdata (vec &dt, ivec &indeces)
| Returns data records at indeces.
void | linkrvs (RV &drv, RV &urv)
| Method that assigns random variables to the datasource. Typically, the datasource will be constructed without knowledge of random variables. This method will associate existing variables with RVs.
void | write (vec &ut)
| Accepts action variable and schedule it for application.
void | write (vec &ut, ivec &indexes)
| Accepts action variables at specific indeces.
void | step ()
| Moves from $t$ to $t+1$, i.e. perfroms the actions and reads response of the system.
| MemDS (mat &Dat, ivec &rowid, ivec &delays)
| Default constructor.
## Protected Attributes
RV | Drv
| Observed variables, returned by `getdata()`.
RV | Urv
| Action variables, accepted by `write()`.

## Detailed Description

Class representing off-line data stored in memory.

The data are stored in an internal matrix `Data` . Each column of Data corresponds to one discrete time observation $t$. Access to this matrix is via indexes `rowid` and `delays`.

The data can be loaded from a file.
