ROOT::Detail::RDF::RJittedDefine Class Reference

A wrapper around a concrete RDefine, which forwards all calls to it RJittedDefine is a placeholder that is put in the collection of custom columns in place of a RDefine that will be just-in-time compiled.

Jitted code will assign the concrete RDefine to this RJittedDefine before the event-loop starts.
