## Detailed Description

Class for storing results (and semi-results) of an experiment.

This class abstracts logging of results from implementation. This class replaces direct logging of results (e.g. to files or to global variables) by calling methods of a logger. Specializations of this abstract class for specific storage method are designed.

## Member Function Documentation

virtual int bdm::logger::add | ( | const RV & | rv,
|  | string | prefix = `""` |
| ) |  |  | `[inline, virtual]`

returns an identifier which will be later needed for calling the `logit()` function For empty RV it returns -1, this entry will be ignored by `logit()`.
