Include dependency graph for RNTupleUtil.hxx:
This graph shows which files directly or indirectly include this file:


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 integer in a struct in order to avoid template specialization clash with std::uint64_t. More...
class  ROOT::Experimental::RColumnSwitch
 Holds the index and the tag of a kSwitch column. More...
struct  ROOT::Experimental::RNTupleCardinality< SizeT >
 Helper types to present an offset column as array of collection sizes. More...
struct  ROOT::Experimental::RNTupleLocator
 Generic information about the physical location of data. More...
struct  ROOT::Experimental::RNTupleLocatorObject64
 RNTupleLocator payload that is common for object stores using 64bit location information. More...


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


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.
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.


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


constexpr ClusterSize_t ROOT::Experimental::kInvalidClusterIndex (std::uint64_t(-1))
template<typename T >
auto ROOT::Experimental::Internal::MakeAliasedSharedPtr (T *rawPtr)
RLogChannelROOT::Experimental::NTupleLog ()
 Log channel for RNTuple diagnostics.


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