Functions
SG::sgkey_t	xAOD::Utils::hash (const std::string &name)
	This function provides a hashed version of the key (branch) names used in the xAOD file, similar to how Athena saves hashed numbers in persistent ElementLinks. More...
std::string	xAOD::Utils::dynBranchPrefix (const std::string &key)
	This function is used to figure out what to name dynamic auxiliary branches coming from a container called key. More...
std::string	xAOD::Utils::dynFieldPrefix (const std::string &key)
	This function is used to figure out what to name dynamic auxiliary field coming from a container called key. More...
const std::type_info &	xAOD::Utils::getTypeInfo (EDataType type)
	This function is used when reading a primitive branch from an input file without the user explicitly asking for it. More...
const std::type_info &	xAOD::Utils::getTypeInfo (std::string_view typeName)
	Get the type info of a primitive variable, in an RNTuple. More...
bool	xAOD::Utils::isPrimitiveType (std::string_view typeName)
	Check if the type name describes a primitive type. More...
char	xAOD::Utils::rootType (char typeidType)
	This function is used internally in the code when creating primitive dynamic auxiliary branches. More...
std::string	xAOD::Utils::getTypeName (const std::type_info &ti)
	This function is necessary in order to create type names that ROOT can understand. More...
std::string	xAOD::Utils::getFirstBranchMatch (TTree *tree, const std::string &pre)
	This function is used to search for a branch in a TTree that contains a given substring. More...
