TTree-backed data storage.
When a file is opened before creating the data storage, the storage will be file-backed. This reduces memory pressure because it allows storing the data in the file and reading it on demand. For a completely memory-backed storage, which is faster than the file-backed storage, RooVectorDataStore can be used.
With tree-backed storage, the tree can be found in the file with the name RooTreeDataStore_name_title
for a dataset created as RooDataSet("name", "title", ...)
.
One can also change between TTree- and std::vector-backed storage using RooAbsData::convertToTreeStore() and RooAbsData::convertToVectorStore().

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.
