53 | * @class AliHLTComponent | |
54 | * Base class of HLT data processing components. | |
55 | * The class provides a common interface for HLT data processing components. | |
56 | * The interface can be accessed from the online HLT framework or the AliRoot | |
57 | * offline analysis framework. | |
a655eae3 | 58 | * @section alihltcomponent-properties Component identification and properties |
59 | * Each component must provide a unique ID, input and output data type indications, | |
60 | * and a spawn function. | |
61 | * @subsection alihltcomponent-req-methods Required property methods | |
62 | * - @ref GetComponentID | |
63 | * - @ref GetInputDataTypes (see @ref alihltcomponent-type for default | |
64 | * implementations.) | |

66 | * implementations.) | |
67 | * - @ref GetOutputDataSize (see @ref alihltcomponent-type for default | |
68 | * implementations.) | |

75 | * @subsection alihltcomponent-processing-mehods Data processing | |
76 | * | |
77 | * | |
78 | * @subsection alihltcomponent-type Component type | |
79 | * Components can be of type | |
90ebac25 | 80 | * - @ref kSource components which only produce data |
81 | * - @ref kProcessor components which consume and produce data | |
82 | * - @ref kSink components which only consume data | |
a655eae3 | 83 | * |
84 | * where data production and consumption refer to the analysis data stream. In | |
85 | * order to indicate the type, a child component can overload the | |
86 | * @ref GetComponentType function. | |
87 | * @subsubsection alihltcomponent-type-std Standard implementations | |
88 | * Components in general do not need to implement this function, standard | |
89 | * implementations of the 3 types are available: | |
90 | * - AliHLTDataSource for components of type @ref kSource <br> | |
91 | * All types of data sources can inherit from AliHLTDataSource and must | |
92 | * implement the @ref AliHLTDataSource::GetEvent method. The class | |
93 | * also implements a standard method for @ref GetInputDataTypes. | |
94 | * | |
95 | * - AliHLTProcessor for components of type @ref kProcessor <br> | |
96 | * All types of data processors can inherit from AliHLTDataSource and must | |
97 | * implement the @ref AliHLTProcessor::DoEvent method. | |
98 | * | |
99 | * - AliHLTDataSink for components of type @ref kSink <br> | |
100 | * All types of data processors can inherit from AliHLTDataSource and must | |
101 | * implement the @ref AliHLTDataSink::DumpEvent method. The class | |
102 | * also implements a standard method for @ref GetOutputDataType and @ref | |
103 | * GetOutputDataSize. | |
104 | * | |
105 | * @subsection alihltcomponent-environment Running environment | |
bfccbf68 | 106 | * |
107 | * In order to adapt to different environments (on-line/off-line), the component | |
108 | * gets an environment structure with function pointers. The base class provides | |
109 | * member functions for those environment dependend functions. The member | |
110 | * functions are used by the component implementation and are re-mapped to the | |
111 | * corresponding functions. | |
a655eae3 | 112 | * @section alihltcomponent-interfaces Component interfaces |
113 | * Each of the 3 standard component base classes AliHLTProcessor, AliHLTDataSource | |
114 | * and AliHLTDataSink provides it's own processing method (see | |
115 | * @ref alihltcomponent-type-std), which splits into a high and a low-level | |
116 | * method. For the @ref alihltcomponent-low-level-interface, all parameters are | |
117 | * shipped as function arguments, the component is supposed to dump data to the | |
118 | * output buffer and handle all block descriptors. | |
119 | * The @ref alihltcomponent-high-level-interface is the standard processing | |
120 | * method and will be used whenever the low-level method is not overloaded. | |
121 | * | |
122 | * @subsection alihltcomponent-high-level-interface High-level interface | |
123 | * The high-level component interface provides functionality to exchange ROOT | |
124 | * structures between components. In contrast to the | |
125 | * @ref alihltcomponent-low-level-interface, a couple of functions can be used | |
126 | * to access data blocks of the input stream | |
127 | * and send data blocks or ROOT TObject's to the output stream. The functionality | |
128 | * is hidden from the user and is implemented by using ROOT's TMessage class. | |
129 | * | |
130 | * @subsubsection alihltcomponent-high-level-int-methods Interface methods | |
131 | * The interface provides a couple of methods in order to get objects from the | |
132 | * input, data blocks (non TObject) from the input, and to push back objects and | |
133 | * data blocks to the output. For convenience there are several functions of | |
134 | * identical name (and similar behavior) with different parameters defined. | |
135 | * Please refer to the function documentation. | |
136 | * - @ref GetNumberOfInputBlocks <br> | |
137 | * return the number of data blocks in the input stream | |
138 | * - @ref GetFirstInputObject <br> | |
139 | * get the first object of a specific data type | |
140 | * - @ref GetNextInputObject <br> | |
141 | * get the next object of same data type as last GetFirstInputObject/Block call | |
142 | * - @ref GetFirstInputBlock <br> | |
143 | * get the first block of a specific data type | |
144 | * - @ref GetNextInputBlock <br> | |
145 | * get the next block of same data type as last GetFirstInputBlock/Block call | |
146 | * - @ref PushBack <br> | |
147 | * insert an object or data buffer into the output | |
148 | * - @ref CreateEventDoneData <br> | |
149 | * add event information to the output | |
150 | * | |
151 | * In addition, the processing methods are simplified a bit by cutting out most of | |
79c114b5 | 152 | * the parameters. |
153 | * @see | |
154 | * - @ref AliHLTProcessor::DoEvent | |
155 | * - @ref AliHLTDataSource::GetEvent | |
156 | * - @ref AliHLTDataSink::DumpEvent | |
a655eae3 | 157 | * |
8451168b | 158 | * \em IMPORTANT: objects and block descriptors provided by the high-level interface |
159 | * <b>MUST NOT BE DELETED</b> by the caller. | |
160 | * | |
a655eae3 | 161 | * @subsubsection alihltcomponent-high-level-int-guidelines High-level interface guidelines |
162 | * - Structures must inherit from the ROOT object base class TObject in order be | |
163 | * transported by the transportation framework. | |
164 | * - all pointer members must be transient (marked <tt>//!</tt> behind the member | |
165 | * definition), i.e. will not be stored/transported, or properly marked | |
166 | * (<tt>//-></tt>) in order to call the streamer of the object the member is pointing | |
167 | * to. The latter is not recomended. Structures to be transported between components | |
168 | * should be streamlined. | |
169 | * - no use of stl vectors/strings, use appropriate ROOT classes instead | |
170 | * | |
171 | * @subsection alihltcomponent-low-level-interface Low-level interface | |
172 | * The low-level component interface consists of the specific data processing | |
173 | * methods for @ref AliHLTProcessor, @ref AliHLTDataSource, and @ref AliHLTDataSink. | |
174 | * - @ref AliHLTProcessor::DoEvent | |
175 | * - @ref AliHLTDataSource::GetEvent | |
176 | * - @ref AliHLTDataSink::DumpEvent | |
177 | * | |
178 | * | |
179 | * @section alihltcomponent-handling Component handling | |
180 | * The handling of HLT analysis components is carried out by the AliHLTComponentHandler. | |
181 | * Component are registered automatically at load-time of the component shared library | |
182 | * under the following suppositions: | |
183 | * - the component library has to be loaded from the AliHLTComponentHandler using the | |
184 | * @ref AliHLTComponentHandler::LoadLibrary method. | |
185 | * - the component implementation defines one global object (which is generated | |
186 | * when the library is loaded) | |
187 | * | |
188 | * @subsection alihltcomponent-design-rules General design considerations | |
189 | * The analysis code should be implemented in one or more destict class(es). A | |
190 | * \em component should be implemented which interface the destict analysis code to the | |
191 | * component interface. This component generates the analysis object dynamically. <br> | |
192 | * | |
193 | * Assume you have an implemetation <tt> AliHLTDetMyAnalysis </tt>, another class <tt> | |
194 | * AliHLTDetMyAnalysisComponent </tt> contains: | |
195 | * <pre> | |
196 | * private: | |
197 | * AliHLTDetMyAnalysis* fMyAnalysis; //! | |
198 | * </pre> | |
199 | * The object should then be instantiated in the DoInit handler of | |
200 | * <tt>AliHLTDetMyAnalysisComponent </tt>, and cleaned in the DoDeinit handler. | |
201 | * | |
202 | * Further rules: | |
203 | * - avoid big static arrays in the component, allocate the memory at runtime | |
