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...

class	ROOT::Experimental::Internal::RColumnIndex
	The in-memory representation of a 32bit or 64bit on-disk index column. More...

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

struct	ROOT::RNTupleCardinality< SizeT >
	Helper types to present an offset column as array of collection sizes. More...

class	ROOT::Experimental::RNTupleLocator
	Generic information about the physical location of data. More...

class	ROOT::Experimental::RNTupleLocatorObject64
	RNTupleLocator payload that is common for object stores using 64bit location information. More...

Namespaces
namespace	ROOT
	tbb::task_arena is an alias of tbb::interface7::task_arena, which doesn't allow to forward declare tbb::task_arena without forward declaring tbb::interface7

namespace	ROOT::Experimental

namespace	ROOT::Experimental::Internal

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

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