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

Template Parameters

Helper	The action helper type, which implements the concrete action logic (e.g. FillHelper, SnapshotHelper)
PrevDataFrame	The type of the parent node in the computation graph
ColumnTypes_t	A TypeList with the types of the input columns
