Detailed Description

Ranks particles by the values of a variable.

The ranking also takes antiparticles into account. The rank information is written to a variable and low ranking candidates can be discarded.

Member Enumeration Documentation

◆ EModulePropFlags

enum EModulePropFlags
inherited

Each module can be tagged with property flags, which indicate certain features of the module.

Enumerator
c_Input 

This module is an input module (reads data).

c_Output 

This module is an output module (writes data).

c_ParallelProcessingCertified 

This module can be run in parallel processing mode safely (All I/O must be done through the data store, in particular, the module must not write any files.)

c_HistogramManager 

This module is used to manage histograms accumulated by other modules.

c_InternalSerializer 

This module is an internal serializer/deserializer for parallel processing.

c_TerminateInAllProcesses 

When using parallel processing, call this module's terminate() function in all processes().

This will also ensure that there is exactly one process (single-core if no parallel modules found) or at least one input, one main and one output process.

c_DontCollectStatistics 

No statistics is collected for this module.

34Per default particles are sorted in descending order but it can be switched to
35an ascending order by setting ``selectLowest=True``. The convenience functions
36`modularAnalysis.rankByHighest` and `modularAnalysis.rankByLowest` set this
37parameter automatically based on their names.
38
39Particles will receive an extra-info field containing their rank as an integer
40starting at 1 (best). The name of this extra-info field defaults to
41``${variable}_rank`` but can be chosen freely using the ``outputVariable``
42parameter.
43
44The ranking also takes antiparticles into account, so there will only be one
45B+- candidate with ``rank=1``. The remaining list is sorted from best to worst
46candidate (each charge, e.g. B+/B-, separately). The sorting is guaranteed
47to be stable between particle and anti particle list: particles with the same
48value for ``variable`` will keep their relative order. That is, a particle "A"
49which was before another particle "B" in the same list and has the same value
50for ``variable`` will also stay before "B" after sorting.

Returns
True if at least one condition and return value exists and at least one condition expression was evaluated to true.

438
439Sets a conditional sub path which will be executed after this
440module if the return value set in the module passes the given ``expression``.
441
442Modules can define a return value (int or bool) using ``setReturnValue()``,
443which can be used in the steering file to split the Path based on this value, for example
444
445>>> module_with_condition.if_value("<1", another_path)
446
447In case the return value of the ``module_with_condition`` for a given event is
448less than 1, the execution will be diverted into ``another_path`` for this event.
449
450You could for example set a special return value if an error occurs, and divert
451the execution into a path containing :b2:mod:`RootOutput` if it is found;
452saving only the data producing/produced by the error.
453
454After a conditional path has executed, basf2 will by default stop processing
455the path for this event. This behaviour can be changed by setting the
456``after_condition_path`` argument.

◆ getFileNames()

virtual std::vector< std::string > getFileNames ( bool  outputFiles)
inlinevirtualinherited

Return a list of output filenames for this modules.

This will be called when basf2 is run with "--dry-run" if the module has set either the c_Input or c_Output properties.

If the parameter outputFiles is false (for modules with c_Input) the list of input filenames should be returned (if any). If outputFiles is true (for modules with c_Output) the list of output files should be returned (if any).

If a module has sat both properties this member is called twice, once for each property.

The module should return the actual list of requested input or produced output filenames (including handling of input/output overrides) so that the grid system can handle input/output files correctly.

This function should return the same value when called multiple times. This is especially important when taking the input/output overrides from Environment as they get consumed when obtained so the finalized list of output files should be stored for subsequent calls.

A simplified version to add a condition to the module.

Please note that successive calls of this function will add more than one condition to the module. If more than one condition results in true, only the last of them will be used.

Please be careful: Avoid creating cyclic paths, e.g. by linking a condition to a path which is processed before the path where this module is located in.

It is equivalent to the if_value() method, using the expression "<1". This method is meant to be used together with the setReturnValue(bool value) method.

Parameters
pathShared pointer to the Path which will be executed if the return value is false.
afterConditionPathWhat to do after executing 'path'.

void setParamPython(const std::string &name, const PythonObject &pyObj)
Implements a method for setting boost::python objects.

◆ setParamPythonDict()

void setParamPythonDict ( const boost::python::dict &  dictionary)
privateinherited

Implements a method for reading the parameter values from a boost::python dictionary.

The key of the dictionary has to be the name of the parameter and the value has to be of one of the supported parameter types.

Parameters
dictionaryThe python dictionary from which the parameter values are read.

◆ setPropertyFlags()

void setPropertyFlags ( unsigned int  propertyFlags)
inherited

Sets the flags for the module properties.

Parameters
propertyFlagsbitwise OR of EModulePropFlags

Definition at line 208 of file Module.cc.

209{
210 m_propertyFlags = propertyFlags;
211}

◆ setReturnValue() [1/2]

void setReturnValue ( bool  value)
protectedinherited

Sets the return value for this module as bool.

The bool value is saved as an integer with the convention 1 meaning true and 0 meaning false. The value can be used in the steering file to divide the analysis chain into several paths.

Parameters
valueThe value of the return value.

Definition at line 227 of file Module.cc.

228{
229 m_hasReturnValue = true;
230 m_returnValue = value;
231}

◆ setReturnValue() [2/2]

void setReturnValue ( int  value)
protectedinherited

Sets the return value for this module as integer.

The value can be used in the steering file to divide the analysis chain into several paths.

Parameters
valueThe value of the return value.

Definition at line 220 of file Module.cc.

221{
222 m_hasReturnValue = true;
223 m_returnValue = value;
224}

◆ setType()

void setType ( const std::string &  type)
protectedinherited

Set the module type.

Only for use by internal modules (which don't use the normal REG_MODULE mechanism).

Definition at line 48 of file Module.cc.
