Include dependency graph for RNTupleUtil.hxx:

This graph shows which files directly or indirectly include this file:

Classes
class	ROOT::Experimental::RClusterIndex
	Addresses a column element or field item relative to a particular cluster, instead of a global NTupleSize_t index. More...

struct	ROOT::Experimental::RClusterSize
	Wrap the 32bit integer in a struct in order to avoid template specialization clash with std::uint32_t. More...

class	ROOT::Experimental::RColumnSwitch
	Holds the index and the tag of a kSwitch column. More...

class	ROOT::Experimental::RNTupleVersion
	For forward and backward compatibility, attach version information to the consitituents of the file format (column, field, cluster, ntuple). More...

Typedefs
using	ROOT::Experimental::ClusterSize_t = RClusterSize

using	ROOT::Experimental::ColumnId_t = std::int64_t
	Uniquely identifies a physical column within the scope of the current process, used to tag pages. More...

using	ROOT::Experimental::DescriptorId_t = std::uint64_t
	Distriniguishes elements of the same type within a descriptor, e.g. different fields. More...

using	ROOT::Experimental::NTupleFlags_t = std::uint64_t
	64 possible flags to apply to all versioned entities (so far unused). More...

using	ROOT::Experimental::NTupleSize_t = std::uint64_t
	Integer type long enough to hold the maximum number of entries in a column. More...

using	ROOT::Experimental::RNTupleUuid = std::string
	Every NTuple is identified by a UUID. TODO(jblomer): should this be a TUUID? More...

Enumerations
enum	ROOT::Experimental::ENTupleStructure { ROOT::Experimental::kLeaf , ROOT::Experimental::kCollection , ROOT::Experimental::kRecord , ROOT::Experimental::kVariant , ROOT::Experimental::kReference }
	The fields in the ntuple model tree can carry different structural information about the type system. More...

Functions
constexpr ClusterSize_t	ROOT::Experimental::kInvalidClusterIndex (std::uint32_t(-1))

Variables
constexpr ColumnId_t	ROOT::Experimental::kInvalidColumnId = -1

constexpr DescriptorId_t	ROOT::Experimental::kInvalidDescriptorId = std::uint64_t(-1)

constexpr NTupleSize_t	ROOT::Experimental::kInvalidNTupleIndex = std::uint64_t(-1)
