61f275d1 | 19 | // an object w.r. to the RSN framework analysis (daughter, mother, event) |
7356f978 | 20 | // which could be used for cut checking or value computing. |
21 | // Since most of these operation are implemented into classes that | |
22 | // operate on any of such objects, then this class helps in making sure | |
23 | // that the object being processed corresponds to what is expected. | |
24 | // It also contains three pointers to which any passed object is casted | |
25 | // in order to have a quick reference to any allowed object type from | |
26 | // an appropriate pointer, which is propagated to all inheriting classes. | |
