23 | ||
31eeed4f | 24 | Revision 1.5 2001/10/23 13:03:35 hristov |
25 | The access to several data members was changed from public to protected. The digitisation was adapted to the multi-event case (J.Chudoba) | |
26 | ||
6e585aa2 | 27 | Revision 1.4 2001/10/21 18:31:24 hristov |
28 | Several pointers were set to zero in the default constructors to avoid memory management problems | |
