void bdm::mpdf::from_setting | ( | const Setting & | set | ) | `[virtual]`

Load from structure with elements:

     { class = "mpdf_offspring",
       rv = {class="RV", names=(...),}; // RV describing meaning of random variable
       rvc= {class="RV", names=(...),}; // RV describing meaning of random variable in condition
       // elements of offsprings
     }
