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().

Base class for Modules.
 
A module is the smallest building block of the framework.
A typical event processing chain consists of a Path containing
modules. By inheriting from this base class, various types of
modules can be created. To use a module, please refer to
:func:`Path.add_module()`.  A list of modules is available by running
``basf2 -m`` or ``basf2 -m package``, detailed information on parameters is
given by e.g. ``basf2 -m RootInput``.
 
The 'Module Development' section in the manual provides detailed information
on how to create modules, setting parameters, or using return values/conditions:

Sets a conditional sub path which will be executed after this
module if the return value set in the module passes the given ``expression``.
 
Modules can define a return value (int or bool) using ``setReturnValue()``,
which can be used in the steering file to split the Path based on this value, for example
 
>>> module_with_condition.if_value("<1", another_path)
 
In case the return value of the ``module_with_condition`` for a given event is
less than 1, the execution will be diverted into ``another_path`` for this event.
 
You could for example set a special return value if an error occurs, and divert
the execution into a path containing :b2:mod:`RootOutput` if it is found;
saving only the data producing/produced by the error.
 
After a conditional path has executed, basf2 will by default stop processing
the path for this event. This behaviour can be changed by setting the
``after_condition_path`` argument.
 
Parameters:
  expression (str): Expression to determine if the conditional path should be executed.
      This should be one of the comparison operators ``<``, ``>``, ``<=``,
      ``>=``, ``==``, or ``!=`` followed by a numerical value for the return value

◆ 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.

◆ getWeightedSumInvDists()

double getWeightedSumInvDists	(	const Particle *	iParticle,

private

Get the sum of the inverse (scaled) minimum distances over the given detector $d$ layers, weighted by the PID detector separation score (if requested):

$\begin{equation} S_{d} = \sum_{d} w_{d} * \frac{D_{d}^{thresh}}{D_{d}} \end{equation}$

The distance $D_{d}$ to the closest track helix extrapolation defined in double getDistAtDetSurface() is used. The scaling at the numerator is the threshold distance for this detector to define close-by tracks. Note that if the PID detector weighting is switched off, $w_{d} = -1$ . By construction, $S_{d}$ is a negative number.

Get the sum of layers with a close-by track, divided by the total number of layers, for the given detector $d$ , weighted by the PID detector separation score (if requested):

$\begin{equation} s_{d} = 1 - \left(-w_{d} \cdot \frac{n_{d}}{N_{d}}\right). \end{equation}$

where $n_{d}$ is the number of layers where a close-enough particle is found, and $w_{d}$ is the weight that each sub-detector has on the PID of the given particle hypothesis (if m_excludePIDDetWeights = true):

The distance to closest track helix extrapolation defined in double getDistAtDetSurface() is used. Note that if the PID detector weighting is switched off, $w_{d} = -1$ .

◆ if_false()

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

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.

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'.
