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.

Member Function Documentation

beginRun()

void beginRun ( void  )

finalvirtualinherited

Reset the m_runCollectOnRun flag, if necessary, to begin collection again.

It seems that the beginRun() function is called in each basf2 subprocess when the run changes in each process. This is nice because it allows us to write the new (exp,run) object creation in the beginRun function as though the other processes don't exist.

Reimplemented from HistoModule.

Definition at line 77 of file CalibrationCollectorModule.cc.

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.

collect()

void collect ( )

overridevirtual

Select events and crystals and accumulate histograms.

< vector derived from DB object

Store the crystal cell id of those being used as the reference crystals for ts. One crystal per crate is defined as having ts=0. This histogram only keeps track of the crystal id, not the crate id. The talg can figure out to which crate to associate the crystal.

Record the input database constants

< number of loose tracks

< number of tight tracks

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.

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, 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.

getPreScaleChoice()

bool getPreScaleChoice ( )

inlineprivateinherited

I'm a little worried about floating point precision when comparing to 0.0 and 1.0 as special values.

But since a user will have set them (or left them as default) as exactly equal to 0.0 or 1.0 rather than calculating them in almost every case, I think we can assume that the equalities hold.

Definition at line 122 of file CalibrationCollectorModule.h.

getReturnValue()

int getReturnValue ( ) const

inlineinherited

Return the return value set by this module.

This value is only meaningful if hasReturnValue() is true

Definition at line 381 of file Module.h.

getType()

const std::string & getType ( ) const

inherited

Returns the type of the module (i.e.

class name minus 'Module')

Definition at line 41 of file Module.cc.

hasProperties()

bool hasProperties ( unsigned int  propertyFlags ) const

inherited

Returns true if all specified property flags are available in this module.

Parameters

propertyFlags

Ored EModulePropFlags which should be compared with the module flags.

Definition at line 160 of file Module.cc.

if_false()

void if_false ( const std::shared_ptr< Path > &  path, 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.

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

path	Shared pointer to the Path which will be executed if the return value is false.
afterConditionPath	What to do after executing 'path'.

Definition at line 85 of file Module.cc.

if_true()

void if_true ( const std::shared_ptr< Path > &  path, EAfterConditionPath  afterConditionPath = EAfterConditionPath::c_End  )
