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

Namespaces

namespace  ROOT
 This file contains a specialised ROOT message handler to test for diagnostic in unit tests.
 
namespace  ROOT::Experimental
 

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

Enumerations

enum  ROOT::Experimental::ENTupleStructure {
  ROOT::Experimental::kLeaf , ROOT::Experimental::kCollection , ROOT::Experimental::kRecord , ROOT::Experimental::kVariant ,
  ROOT::Experimental::kReference , ROOT::Experimental::kInvalid
}
 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))
 
RLogChannel & ROOT::Experimental::NTupleLog ()
 Log channel for RNTuple diagnostics. More...
 

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)
