ROOT::Internal::RDF::RJittedVariation Class Reference

A wrapper around a concrete RVariation, which forwards all calls to it RJittedVariation is a placeholder that is inserted in the computation graph in place of a RVariation that will be just-in-time compiled.

Jitted code will assign the concrete RVariation to this RJittedVariation before the event-loop starts.
