Function Documentation

◆ checkIfRangesOverlap()

bool RooHelpers::checkIfRangesOverlap ( RooAbsPdf const &  pdf,
RooAbsData const &  data,
std::vector< std::string > const &  rangeNames 
)

Check if there is any overlap when a list of ranges is applied to a set of observables.

Parameters
[in]argRooAbsCollection with the observables to check for overlap.
[in]rangeNameThe names of the ranges.

Definition at line 183 of file RooHelpers.cxx.

◆ checkRangeOfParameters()

void RooHelpers::checkRangeOfParameters ( const RooAbsReal callingClass,
std::initializer_list< const RooAbsReal * >  pars,
double  min,
double  max,
bool  limitsInAllowedRange,
std::string const &  extraMessage 
)

Check if the parameters have a range, and warn if the range extends below / above the set limits.

Parameters
[in]callingClassClass that's calling. Needed to include name and type name of the class in error message.
[in]parsList of all parameters to be checked.
[in]minMinimum of allowed range. min itself counts as disallowed.
[in]maxMaximum of allowed range. max itself counts as disallowed.
[in]limitsInAllowedRangeIf true, the limits passed as parameters are part of the allowed range.
[in]extraMessageMessage that should be appended to the warning.

◆ getColonSeparatedNameString()

std::string RooHelpers::getColonSeparatedNameString ( RooArgSet const &  argSet)

Create a string with all sorted names of RooArgSet elements separated by colons.

Parameters
[in]argargSet The input RooArgSet.

Definition at line 248 of file RooHelpers.cxx.

◆ getRangeOrBinningInterval()

std::pair< double, double > RooHelpers::getRangeOrBinningInterval ( RooAbsArg const *  arg,
const char *  rangeName 
)

Get the lower and upper bound of parameter range if arg can be casted to RooAbsRealLValue.

If no range with rangeName is defined for the argument, this will check if a binning of the same name exists and return the interval covered by the binning. Returns {-infinity, infinity} if agument can't be casted to RooAbsRealLValue* or if no range or binning with the requested name exists.

Parameters
[in]argRooAbsArg for which to get the range.
[in]rangeNameThe name of the range.

Definition at line 167 of file RooHelpers.cxx.

◆ selectFromArgSet()

RooArgSet RooHelpers::selectFromArgSet ( RooArgSet const &  argSet,
std::string const &  names 
)

Construct a RooArgSet of objects in a RooArgSet whose names match to those in the names string.

Parameters
[in]argargSet The input RooArgSet.
[in]argnames The names of the objects to select in a colon-separated string.
