Detailed Description

Creates for each Particle in given ParticleList an RestOfEvent (ROE) dataobject and makes basf2 relation between them.

Takes as first input parameter the name of target particle list, around which the RestOfEvent will be constructed. The ROE particles are taken from default particle lists 'gamma:roe_default', 'pi+:roe_default' and 'K_L0:myroe_default', which defines the default particle type hypotheses: gammas, pions and K-longs. Second input parameter is an array of final-state particle list names, which are preselected by PID, for example: if the module is launched with particleListsInput=['K+:good','e+:good'], it will create ROE object filled with these particle track hypotheses first and all other particles with default particle hypotheses.

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.)

◆ beginRun()

virtual void beginRun ( void )

inlinevirtualinherited

Called when entering a new run.

Called at the beginning of each run, the method gives you the chance to change run dependent constants like alignment parameters, etc.

This method can be implemented by subclasses.

Definition at line 147 of file Module.h.

◆ clone()

std::shared_ptr< PathElement > clone ( ) const

overridevirtualinherited

Create an independent copy of this module.

Note that parameters are shared, so changing them on a cloned module will also affect the original module.

Implements PathElement.

Definition at line 179 of file Module.cc.

◆ def_endRun()

virtual void def_endRun ( )

inlineprotectedvirtualinherited

This method can receive that the current run ends as a call from the Python side.

For regular C++-Modules that forwards the call to the regular endRun() method.

Reimplemented in PyModule.

Definition at line 439 of file Module.h.

◆ def_initialize()

virtual void def_initialize ( )

inlineprotectedvirtualinherited

Wrappers to make the methods without "def_" prefix callable from Python.

Overridden in PyModule. Wrapper method for the virtual function initialize() that has the implementation to be used in a call from Python.

Reimplemented in PyModule.

Definition at line 420 of file Module.h.

◆ endRun()

virtual void endRun ( void )

inlinevirtualinherited

This method is called if the current run ends.

Use this method to store information, which should be aggregated over one run.

This method can be implemented by subclasses.

Definition at line 166 of file Module.h.

◆ evalCondition()

bool evalCondition ( ) const

inherited

If at least one condition was set, it is evaluated and true returned if at least one condition returns true.

If no condition or result value was defined, the method returns false. Otherwise, the condition is evaluated and true returned, if at least one condition returns true. To speed up the evaluation, the condition strings were already parsed in the method if_value().

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

Definition at line 96 of file Module.cc.

◆ getAfterConditionPath()

Module::EAfterConditionPath getAfterConditionPath ( ) const

inherited

What to do after the conditional path is finished.

(defaults to c_End if no condition is set)

Definition at line 133 of file Module.cc.

◆ getConditionPath()

std::shared_ptr< Path > getConditionPath ( ) const

inherited

Returns the path of the last true condition (if there is at least one, else reaturn a null pointer).

Definition at line 113 of file Module.cc.

◆ 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.

Reimplemented in RootOutputModule, StorageRootOutputModule, and RootInputModule.

Definition at line 134 of file Module.h.

◆ getName()

const std::string& getName ( ) const

inlineinherited

Returns the name of the module.

This can be changed via e.g. set_name() in the steering file to give more useful names if there is more than one module of the same type.

For identifying the type of a module, using getType() (or type() in Python) is recommended.

Definition at line 187 of file Module.h.

◆ getParamInfoListPython()

std::shared_ptr< boost::python::list > getParamInfoListPython ( ) const

inherited

Returns a python list of all parameters.

Each item in the list consists of the name of the parameter, a string describing its type, a python list of all default values and the description of the parameter.

Returns: A python list containing the parameters of this parameter list.

Definition at line 279 of file Module.cc.

		EAfterConditionPath	afterConditionPath = `EAfterConditionPath::c_End`
	)

inherited

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.
