18 * @defgroup alihlt_system HLT integration into AliRoot
19 * This section describes the HLT integration into AliRoot.
fb345ed7 20 *
21 * @section alihlt_system_intro General Remarks
22 * The HLT analysis is organized in components which can also be used
23 * in off-line processing. Two different types of off-line applications
24 * can be distinguished:
25 * - AliRoot simulation (AliSimulation)
26 * - AliRoot reconstruction (AliReconstruction)
27 *
030da833 28 * In either case an HLT chain described by means of AliHLTConfiguration
29 * builds the core of any HLT application. Special components exist, which
30 * emulate the behavior of the components of the HLT on-line data
fb345ed7 31 * transportation framework. Together with the analysis components, this
32 * allows the full emulation of the behavoir of HLT analysis chain off-line.
33 *
34 * More details how to setup up such a chain can be found:
35 * - The examples page under @ref tut_hltsystem
36 *
37 * @section alihlt_system_simulation AliRoot simulation
38 * HLT has a special role in the normal data flow of simulation and
39 * reconstruction. Since the HLT reconstruction and analysis runs on-line
40 * on the HLT farm, the raw data produced by HLT as a detector contains
41 * already reconstructed events. Consequently, the HLT response has to be
42 * simulated as well as the data of all other detectors.
43 *
44 * Since the detector data is needed, the HLT simulation is run at the
45 * end of AliSimulation.
46 *
47 * As a matter of fact, HLT always reconstructs data, <em><b>HLT simulation
48 * </b></em> means <em><b>HLT reconstruction embedded into AliRoot</b></em>.
49 *
50 * More Details an be found in the module:
51 * - @ref alihlt_aliroot_simulation
52 *
53 * @section alihlt_system_reconstruction AliRoot reconstruction
54 *
55 * Like all other ALICE detectors, HLT utilizes the AliReconstruction interface
56 * to implement a plugin for the AliRoot reconstruction. The reconstructor can be
57 * used to
58 * - run HLT analysis chains in the AliRoot reconstruction <br>
59 * This option is mainly intended for the development and debugging cycle. HLT
60 * chains can be defined by means of AliHLTConfiguration and can be run either
61 * stand-alone or embedded into the AliReconstruction cycle.
62 * - run the default analysis chains <br>
63 * HLT modules can define default analysis chains to be run during AliRoot
64 * reconstruction.
65 * - handle the HLTOUT data<br>
66 * The HLT output stream contains multiple data blocks produced by the various
67 * components of the HLT chain. Each block might need different and even
68 * detector specific processing, like e.g. the processing of ESD objects or the
69 * handling of compressed data.
70 *

95 * Main class for the HLT integration into AliRoot.
b22e91eb 96 * @note This class is only used for the @ref alihlt_system.
97 *
030da833 98 * @section alihltsystem_overview Main functionality
99 * The class implements the main binding functionality to run HLT
100 * embedded in AliRoot:
101 * - creates handlers for HLT components (AliHLTComponentHandler)
102 * and configurations (AliHLTConfigurationHandler).
103 * - implements the creation of a task list from configurations
104 * - runs the tasks of the task list
105 * - implements the interface to AliHLTReconstructor and AliHLTSimulation
106 * - manages the registered module agents (AliHLTModuleAgent)
107 *
108 * @section alihltsystem_functions Main functions
109 * The following list gives the most important functions, see documentation
110 * of functions for details.
111 * - ScanOptions(const char*) initialize the system from arguments
112 * - BuildTaskList(const char*) build task list for a reconstruction chain
113 * - Run() processing loop for task list
114 * - Reconstruct() interface to AliHLTReconstructor
115 * - ProcessHLTOUT() process an HLTOUT colection
116 *
117 * @section alihltsystem_initialization Initialization
118 * AliHLTSystem is initialized with a list of component libraries which determine
119 * the actual functionality. See ScanOptions() for description of options.
120 *
121 * @section alihltsystem_usage Usage
122 * The class AliHLTPluginBase handles the global instance of AliHLTSystem,
123 * the instance is created and fetched like
124 * <pre>
125 * // setup the HLT system
126 * AliHLTSystem* pHLT=AliHLTPluginBase::GetInstance();
127 * </pre>
