## Detailed Description

Datalink that buffers delayed values - do not forget to call step().

Up is current data, Down is their subset with possibly delayed values

`#include <bdmbase.h>`

List of all members.

## Public Member Functions
void | step (const vec &val_up)
| push current data to history
vec | pushdown (const vec &val_up)
| Get val for myself from val of "Up".
void | filldown (const vec &val_up, vec &val_down)
| Get val for vector val_down from val of "Up".
void | set_connection (const RV &rv, const RV &rv_up)
| set connection, rv must be fully present in rv_up
void | set_history (const RV &rv1, const vec &hist0)
| set history of variable given by `rv1` to values of `hist`.
virtual void | set_connection (int ds, int us, const ivec &upind)
| set connection using indices
virtual void | pushup (vec &val_up, const vec &val)
| Fill val of "Up" by my pieces.
int | _upsize ()
| access functions
int | _downsize ()
| access functions
## Protected Attributes
vec | history
| History, ordered as .
RV | Hrv
| rv of the history
ivec | h2v_down
| h2v : indeces in down
ivec | h2v_hist
| h2v : indeces in history
ivec | v2h_up
| v2h: indeces of up too be pushed to h
ivec | v2v_down
| indeces of values in vector downsize
int | downsize
| Remember how long val should be.
int | upsize
| Remember how long val of "Up" should be.
ivec | v2v_up
| val-to-val link, indices of the upper val
