RooCompositeDataStore Class Reference

Combines several disjunct datasets into one.

This is useful for simultaneous PDFs that do not depend on the same observable such as a PDF depending on x combined with another one depending on y. The composite storage will store two different datasets, {x} and {y}, but they can be passed as a single dataset to RooFit operations. A category tag will define which dataset has to be passed to which likelihood.

When iterated from start to finish, datasets will be traversed in the order of the category index.
