19 | Using automatic streamer for c arrays | |
20 | ||
712d6528 | 21 | Revision 1.3 2000/03/20 14:22:25 fca |
22 | New version to support new PHOS code | |
23 | ||
65a2d2b0 | 24 | Revision 1.2 2000/02/15 09:43:54 fca |
25 | Corrections | |
26 | - a bug in the streamer (wrong size of the arrays) | |
27 | - replace Read/WriteArray by Read/WriteFastArray (suggestion R.Brun) | |
