3 | * @file split-hltout.C | |
4 | * @brief Example for the AliHLTOUTPublisherComponent | |
5 | * | |
6 | * Example macro to run a small chain with the AliHLTOUTPublisherComponent. | |
7 | * The AliHLTOUTPublisherComponent is a tool to publish data blocks from | |
8 | * the HLTOUT data stream into an AliHLT reconstruction chain. | |
9 | * | |
10 | * Usage: aliroot -b -q split-hltout.C | tee split-hltout.log | |
11 | * | |
12 | * The macro asumes HLTOUT raw data ddl files in order to open an | |
13 | * AliRawReaderFile, e.g. simulated by sim-hlt-rawddl.C. A small chain with | |
14 | * just a FileWriter connected is run embedded into AliReconstruction. | |
15 | * | |
16 | * \b Note: The example disables a few steps in the AliReconstruction, | |
17 | * mainly because of crashes in various parts of AliRoot. This does not | |
18 | * have any impact to the HLT features to be presented. | |
