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

Classes

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::RNTupleLocalIndex
 Addresses a column element or field item relative to a particular cluster, instead of a global NTupleSize_t index. More...
 
class  ROOT::RNTupleLocator
 Generic information about the physical location of data. More...
 
class  ROOT::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
 
namespace  ROOT::Internal
 

Typedefs

using ROOT::DescriptorId_t = std::uint64_t
 Distriniguishes elements of the same type within a descriptor, e.g. different fields.
 
using ROOT::NTupleSize_t = std::uint64_t
 Integer type long enough to hold the maximum number of entries in a column.
