1e96b53e | 30 | Revision 1.16 2002/06/19 21:12:37 nilsen |
31 | Fixed bug with non-zero-ed new data members in constructors. Thanks Jiri | |
32 | for finding it and pointing it out. | |
33 | ||
07265b7c | 34 | Revision 1.15 2002/06/12 18:59:47 nilsen |
35 | Added Starting track location to hit class and related changes to modules. | |
36 | This is at present still fully backwards compatible since starting hits | |
37 | are still written to the file. When aliroot v4.0 will be released, this | |
38 | backwards compatiblity will be broken by removing the enterence hit, and making | |
39 | the nessesary changes to module at that time. | |
