Functions

template<typename NodeType >
RNode ROOT::RDF::AsRNode (NodeType node)
 Cast a RDataFrame node to the common type ROOT::RDF::RNode. More...
 
template<typename F , typename Args = typename ROOT::TypeTraits::CallableTraits<std::decay_t<F>>::arg_types_nodecay, typename Ret = typename ROOT::TypeTraits::CallableTraits<std::decay_t<F>>::ret_type>
auto ROOT::RDF::Not (F &&f) -> decltype(RDFInternal::NotHelper(Args(), std::forward< F >(f)))
 Given a callable with signature bool(T1, T2, ...) return a callable with same signature that returns the negated result. More...
 
template<typename... ArgTypes, typename F >
std::function< bool(ArgTypes...)> ROOT::Internal::RDF::NotHelper (ROOT::TypeTraits::TypeList< ArgTypes... >, F &&f)
 
template<typename... ArgTypes, typename Ret , typename... Args>
std::function< bool(ArgTypes...)> ROOT::Internal::RDF::NotHelper (ROOT::TypeTraits::TypeList< ArgTypes... >, Ret(*f)(Args...))
 
template<std::size_t N, typename T , typename F >
auto ROOT::Internal::RDF::PassAsVec (F &&f) -> PassAsVecHelper< std::make_index_sequence< N >, T, F >
 
template<std::size_t N, typename T , typename F >
auto ROOT::RDF::PassAsVec (F &&f) -> RDFInternal::PassAsVecHelper< std::make_index_sequence< N >, T, F >
 PassAsVec is a callable generator that allows passing N variables of type T to a function as a single collection. More...
 
void ROOT::RDF::RunGraphs (std::vector< RResultHandle > handles)
 Trigger the event loop of multiple RDataFrames concurrently. More...
 
template<typename NodeType >
std::string ROOT::RDF::SaveGraph (NodeType node)
 Create a graphviz representation of the dataframe computation graph, return it as a string. More...
 
template<typename NodeType >
void ROOT::RDF::SaveGraph (NodeType node, const std::string &outputFile)
 Create a graphviz representation of the dataframe computation graph, write it to the specified file. More...
 
template<typename T >
RResultMap< T > ROOT::RDF::Experimental::VariationsFor (RResultPtr< T > resPtr)
 Produce all required systematic variations for the given result. More...
