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 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::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...
 
struct  ROOT::Experimental::RNTupleOpenSpec
 Used to specify the underlying RNTuples in RNTupleProcessor and RNTupleReader::OpenFriends() 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::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.
