63 * @class AliHLTComponent
64 * Base class of HLT data processing components.
65 * The class provides a common interface for HLT data processing components.
66 * The interface can be accessed from the online HLT framework or the AliRoot
67 * offline analysis framework.
a655eae3 68 * @section alihltcomponent-properties Component identification and properties
69 * Each component must provide a unique ID, input and output data type indications,
70 * and a spawn function.
71 * @subsection alihltcomponent-req-methods Required property methods
72 * - @ref GetComponentID
73 * - @ref GetInputDataTypes (see @ref alihltcomponent-type for default
74 * implementations.)
75 * - @ref GetOutputDataType (see @ref alihltcomponent-type for default
76 * implementations.)
77 * - @ref GetOutputDataSize (see @ref alihltcomponent-type for default

83 * - @ref DoDeinit

85 * If the component has multiple output data types @ref GetOutputDataType
86 * should return @ref kAliHLTMultipleDataType. The framework will invoke
87 * @ref GetOutputDataTypes, a list can be filled.
a655eae3 88 *
89 * @subsection alihltcomponent-processing-mehods Data processing
90 *
91 *
92 * @subsection alihltcomponent-type Component type
93 * Components can be of type
90ebac25 94 * - @ref kSource components which only produce data
95 * - @ref kProcessor components which consume and produce data
96 * - @ref kSink components which only consume data
a655eae3 97 *
98 * where data production and consumption refer to the analysis data stream. In
99 * order to indicate the type, a child component can overload the
100 * @ref GetComponentType function.
101 * @subsubsection alihltcomponent-type-std Standard implementations
102 * Components in general do not need to implement this function, standard
103 * implementations of the 3 types are available:
104 * - AliHLTDataSource for components of type @ref kSource <br>
105 * All types of data sources can inherit from AliHLTDataSource and must
106 * implement the @ref AliHLTDataSource::GetEvent method. The class
107 * also implements a standard method for @ref GetInputDataTypes.
108 *
109 * - AliHLTProcessor for components of type @ref kProcessor <br>
110 * All types of data processors can inherit from AliHLTDataSource and must
111 * implement the @ref AliHLTProcessor::DoEvent method.
112 *
113 * - AliHLTDataSink for components of type @ref kSink <br>
114 * All types of data processors can inherit from AliHLTDataSource and must
115 * implement the @ref AliHLTDataSink::DumpEvent method. The class
116 * also implements a standard method for @ref GetOutputDataType and @ref
117 * GetOutputDataSize.
118 *
119 * @subsection alihltcomponent-environment Running environment
bfccbf68 120 *
121 * In order to adapt to different environments (on-line/off-line), the component
122 * gets an environment structure with function pointers. The base class provides
123 * member functions for those environment dependend functions. The member
124 * functions are used by the component implementation and are re-mapped to the
125 * corresponding functions.
b6800be0 126 *
a655eae3 127 * @section alihltcomponent-interfaces Component interfaces
128 * Each of the 3 standard component base classes AliHLTProcessor, AliHLTDataSource
129 * and AliHLTDataSink provides it's own processing method (see
130 * @ref alihltcomponent-type-std), which splits into a high and a low-level
131 * method. For the @ref alihltcomponent-low-level-interface, all parameters are
132 * shipped as function arguments, the component is supposed to dump data to the
133 * output buffer and handle all block descriptors.
134 * The @ref alihltcomponent-high-level-interface is the standard processing
135 * method and will be used whenever the low-level method is not overloaded.
136 *
b6800be0 137 * In both cases it is necessary to calculate/estimate the size of the output
138 * buffer before the processing. Output buffers can never be allocated inside
139 * the component because of the push-architecture of the HLT.
140 * For that reason the @ref GetOutputDataSize function should return a rough
141 * estimatian of the data to be produced by the component. The component is
142 * responsible for checking the memory size and must return -ENOSPC if the
143 * available buffer is to small, and update the estimator respectively. The
144 * framework will allocate a buffer of appropriate size and call the processing
145 * again.
146 *
b426991e 147 * @subsection alihltcomponent-error-codes Data processing
148 * For return codes, the following scheme applies:
149 * - The data processing methods have to indicate error conditions by a negative
150 * error/return code. Preferably the system error codes are used like
151 * e.g. -EINVAL. This requires to include the header
152 * <pre>
616eb170 153 * \#include \<cerrno\>
b426991e 154 * </pre>
155 * - If no suitable input block could be found (e.g. no clusters for the TPC cluster
156 * finder) set size to 0, block list is empty, return 0
157 * - If no ususable or significant signal could be found in the input blocks
158 * return an empty output block, set size accordingly, and return 0. An empty output
159 * block here could be either a real empty one of size 0 (in which case size also
160 * would have to be set to zero) or a block filled with just the minimum necessary
161 * accounting/meta-structures. E.g. in the TPC
162 *
a655eae3 163 * @subsection alihltcomponent-high-level-interface High-level interface
164 * The high-level component interface provides functionality to exchange ROOT
165 * structures between components. In contrast to the
166 * @ref alihltcomponent-low-level-interface, a couple of functions can be used
167 * to access data blocks of the input stream
168 * and send data blocks or ROOT TObject's to the output stream. The functionality
169 * is hidden from the user and is implemented by using ROOT's TMessage class.
170 *
171 * @subsubsection alihltcomponent-high-level-int-methods Interface methods
172 * The interface provides a couple of methods in order to get objects from the
173 * input, data blocks (non TObject) from the input, and to push back objects and
174 * data blocks to the output. For convenience there are several functions of
175 * identical name (and similar behavior) with different parameters defined.
176 * Please refer to the function documentation.
177 * - @ref GetNumberOfInputBlocks <br>
178 * return the number of data blocks in the input stream
179 * - @ref GetFirstInputObject <br>
180 * get the first object of a specific data type
181 * - @ref GetNextInputObject <br>
182 * get the next object of same data type as last GetFirstInputObject/Block call
183 * - @ref GetFirstInputBlock <br>
184 * get the first block of a specific data type
185 * - @ref GetNextInputBlock <br>
186 * get the next block of same data type as last GetFirstInputBlock/Block call
187 * - @ref PushBack <br>
188 * insert an object or data buffer into the output
189 * - @ref CreateEventDoneData <br>
190 * add event information to the output
191 *
192 * In addition, the processing methods are simplified a bit by cutting out most of
79c114b5 193 * the parameters.
194 * @see
195 * - @ref AliHLTProcessor::DoEvent
196 * - @ref AliHLTDataSource::GetEvent
197 * - @ref AliHLTDataSink::DumpEvent
a655eae3 198 *
8451168b 199 * \em IMPORTANT: objects and block descriptors provided by the high-level interface
200 * <b>MUST NOT BE DELETED</b> by the caller.
201 *
a655eae3 202 * @subsubsection alihltcomponent-high-level-int-guidelines High-level interface guidelines
203 * - Structures must inherit from the ROOT object base class TObject in order be
204 * transported by the transportation framework.
205 * - all pointer members must be transient (marked <tt>//!</tt> behind the member
206 * definition), i.e. will not be stored/transported, or properly marked
207 * (<tt>//-></tt>) in order to call the streamer of the object the member is pointing
208 * to. The latter is not recomended. Structures to be transported between components
209 * should be streamlined.
210 * - no use of stl vectors/strings, use appropriate ROOT classes instead
211 *
212 * @subsection alihltcomponent-low-level-interface Low-level interface
213 * The low-level component interface consists of the specific data processing
214 * methods for @ref AliHLTProcessor, @ref AliHLTDataSource, and @ref AliHLTDataSink.
215 * - @ref AliHLTProcessor::DoEvent
216 * - @ref AliHLTDataSource::GetEvent
217 * - @ref AliHLTDataSink::DumpEvent
218 *
219 *
220 * @section alihltcomponent-handling Component handling
221 * The handling of HLT analysis components is carried out by the AliHLTComponentHandler.
222 * Component are registered automatically at load-time of the component shared library
223 * under the following suppositions:
224 * - the component library has to be loaded from the AliHLTComponentHandler using the
225 * @ref AliHLTComponentHandler::LoadLibrary method.
226 * - the component implementation defines one global object (which is generated
227 * when the library is loaded)
228 *
229 * @subsection alihltcomponent-design-rules General design considerations
230 * The analysis code should be implemented in one or more destict class(es). A
231 * \em component should be implemented which interface the destict analysis code to the
232 * component interface. This component generates the analysis object dynamically. <br>
233 *
234 * Assume you have an implemetation <tt> AliHLTDetMyAnalysis </tt>, another class <tt>
235 * AliHLTDetMyAnalysisComponent </tt> contains:
236 * <pre>
237 * private:
238 * AliHLTDetMyAnalysis* fMyAnalysis; //!
239 * </pre>
240 * The object should then be instantiated in the DoInit handler of
241 * <tt>AliHLTDetMyAnalysisComponent </tt>, and cleaned in the DoDeinit handler.
242 *
243 * Further rules:
244 * - avoid big static arrays in the component, allocate the memory at runtime
