## Member Function Documentation

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

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()`.

                    type = "itpplog";
                    filename = "file_name.it"; // resulting filename with results in it format
                    maxlen = 100;          // size of memory buffer

Reimplemented from bdm::root.
