inlineprotected

Definition at line 586 of file RooVectorDataStore.h.

◆ addColumn()

RooAbsArg * RooVectorDataStore::addColumn ( RooAbsArg newVar,
Bool_t  adjustRange = kTRUE 
)
overridevirtual

Add a new column to the data set which holds the pre-calculated values of 'newVar'.

This operation is only meaningful if 'newVar' is a derived value.

The return value points to the added element holding 'newVar's value in the data collection. The element is always the corresponding fundamental type of 'newVar' (e.g. a RooRealVar if 'newVar' is a RooFormulaVar)

Note: This function is explicitly NOT intended as a speed optimization opportunity for the user. Components of complex PDFs that can be precalculated with the dataset are automatically identified as such and will be precalculated when fitting to a dataset

By forcibly precalculating functions with non-trivial Jacobians, or functions of multiple variables occurring in the data set, using addColumn(), you may alter the outcome of the fit.

Only in cases where such a modification of fit behaviour is intentional, this function should be used.

◆ getWeightBatch()

RooSpan< const double > RooVectorDataStore::getWeightBatch ( std::size_t  first,

) const
overridevirtual

Return the weights of all events in the range [first, first+len).

If an array with weights is stored, a batch with these weights will be returned. If no weights are stored, an empty batch is returned. Use weight() to check if there's a constant weight.
