Namespaces
namespace	ROOT
	This file contains a specialised ROOT message handler to test for diagnostic in unit tests.
namespace	ROOT::Detail
	Special implementation of ROOT::RRangeCast for TCollection, including a check that the cast target type inherits from TObject and a new constructor that takes the TCollection by pointer.

Functions
template<typename T >
constexpr std::size_t	ROOT::Internal::RDF::CacheLineStep ()
	Stepping through CacheLineStep<T> values in a vector<T> brings you to a new cache line.

std::string	ROOT::Internal::RDF::ColumnName2ColumnTypeName (const std::string &colName, TTree *tree, RDataSource *ds, RDefineBase *define, bool vector2rvec)
	Return a string containing the type of the given branch.
template<typename T >
void	ROOT::Internal::RDF::Erase (const T &that, std::vector< T > &v)
	Erase that element from vector v
template<typename T >
constexpr std::size_t	ROOT::Internal::RDF::FindIdxTrue (const T &arr)
unsigned int	ROOT::Internal::RDF::GetColumnWidth (const std::vector< std::string > &names, const unsigned int minColumnSpace=8u)
	Get optimal column width for printing a table given the names and the desired minimal space between columns.
unsigned int	ROOT::Internal::RDF::GetNSlots ()
template<std::size_t N, typename... Ts>
decltype(auto)	ROOT::Internal::RDF::GetNthElement (Ts &&...args)
Long64_t	ROOT::Internal::RDF::InterpreterCalc (const std::string &code, const std::string &context="")
	Jit code in the interpreter with TInterpreter::Calc, throw in case of errors.
void	ROOT::Internal::RDF::InterpreterDeclare (const std::string &code)
	Declare code in the interpreter via the TInterpreter::Declare method, throw in case of errors.
bool	ROOT::Internal::RDF::IsInternalColumn (std::string_view colName)
	Whether custom column with name colName is an "internal" column such as rdfentry_ or rdfslot_.
bool	ROOT::Internal::RDF::IsStrInVec (const std::string &str, const std::vector< std::string > &vec)
ROOT::Experimental::RLogChannel &	ROOT::Detail::RDF::RDFLogChannel ()
std::vector< std::string >	ROOT::Internal::RDF::ReplaceDotWithUnderscore (const std::vector< std::string > &columnNames)
	Replace occurrences of '.
std::string	ROOT::Internal::RDF::TypeID2TypeName (const std::type_info &id)
	Returns the name of a type starting from its type_info An empty string is returned in case of failure References and pointers are not supported since those cannot be stored in columns.
char	ROOT::Internal::RDF::TypeName2ROOTTypeName (const std::string &b)
	Convert type name (e.g.
const std::type_info &	ROOT::Internal::RDF::TypeName2TypeID (const std::string &name)
	Return the type_info associated to a name.
template<typename T >
std::vector< T >	ROOT::Internal::RDF::Union (const std::vector< T > &v1, const std::vector< T > &v2)
	Return a vector with all elements of v1 and v2 and duplicates removed.
