22 | * @class AliHLTDummyComponent | |
23 | * @brief A dummy HLT processing component. | |
24 | * | |
25 | * An implementiation of a dummy component that just copies its input data | |
26 | * as a test, demonstration, and example of the HLT component scheme. | |
833b3167 | 27 | * <h2>General properties:</h2> |
28 | * | |
29 | * Component ID: \b Dummy <br> | |
30 | * Library: \b libAliHLTSample.so <br> | |
31 | * Input Data Types: @ref kAliHLTAnyDataType <br> | |
32 | * | |
33 | * Output Data Types: depending on input blocks | |
34 | * | |
35 | * <h2>Mandatory arguments:</h2> | |
36 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |
37 | * | |
38 | * <h2>Optional arguments:</h2> | |
39 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |
40 | * \li -output_percentage <br> | |
41 | * The fraction (%) of the input data to be copied to the output | |
42 | * | |
43 | * <h2>Configuration:</h2> | |
44 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |
45 | * | |
46 | * <h2>Default CDB entries:</h2> | |
47 | * The component has no default CDB entry. | |
48 | * It does not load any configuration from the global <tt>ConfigHLT</tt> | |
49 | * folder. | |
50 | * | |
51 | * <h2>Performance:</h2> | |
52 | * The component does not have any event data processing. | |
53 | * | |
54 | * <h2>Memory consumption:</h2> | |
55 | * The component does not have any event data processing. | |
56 | * | |
57 | * <h2>Output size:</h2> | |
58 | * Output multiplier determined by option -output_percentage | |
