RooVectorDataStore Class Reference

RooVectorDataStore uses std::vectors to store data columns.

Each of these vectors is associated to an instance of a RooAbsReal, whose values it represents. Those RooAbsReal are the observables of the dataset. In addition to the observables, a data column can be bound to a different instance of a RooAbsReal (e.g., the column "x" can be bound to the observable "x" of a computation graph using attachBuffers()). In this case, a get() operation writes the value of the requested column into the bound real.

As a faster alternative to loading values one-by-one, one can use the function getBatches(), which returns spans pointing directly to the data.

Definition at line 1495 of file RooVectorDataStore.cxx.

◆ 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.
