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