template<typename Helper, typename PrevDataFrame, typename ColumnTypes_t>
class ROOT::Internal::RDF::RActionCRTP< RAction< Helper, PrevDataFrame, ColumnTypes_t > >

A common template base class for all RActions.

Avoids code repetition for specializations of RActions for different helpers, implementing all of the common logic.
