22 | /// | |
23 | /// This macro is used to check the timing (speed) performance of the existing | |
24 | /// offline decoder for the trigger DDLs and also for the new high performance | |
25 | /// decoder. It can be invoked as follows: | |
26 | /// | |
27 | /// $ aliroot | |
28 | /// .L $ALICE_ROOT/MUON/MUONTimeRawStreamTrigger.C+ | |
29 | /// MUONTimeRawStreamTrigger(filename, maxEvent); | |
30 | /// | |
31 | /// where \em filename is the name of a file containing the raw data, or alternatively | |
32 | /// the directory containing rawX (X being an integer) paths with the raw DDL | |
33 | /// data. The \em maxEvent value is the maximum event to process (default set to | |
34 | /// 1000). Thus the macro will time the algorithm for all events in the range | |
35 | /// [0 .. maxEvent-1]. | |
