Member Data Documentation

fCompressionSettings

std::optional<std::uint32_t> ROOT::RClusterDescriptor::RColumnRange::fCompressionSettings

private

The usual format for ROOT compression settings (see Compression.h).

The pages of a particular column in a particular cluster are all compressed with the same settings. If unset, the compression settings are undefined (deferred columns, suppressed columns).

Definition at line 262 of file RNTupleDescriptor.hxx.

fFirstElementIndex

ROOT::NTupleSize_t ROOT::RClusterDescriptor::RColumnRange::fFirstElementIndex = ROOT::kInvalidNTupleIndex

private

The global index of the first column element in the cluster.

Definition at line 256 of file RNTupleDescriptor.hxx.

fIsSuppressed

bool ROOT::RClusterDescriptor::RColumnRange::fIsSuppressed = false

private

Suppressed columns have an empty page range and unknown compression settings.

Their element index range, however, is aligned with the corresponding column of the primary column representation (see Section "Suppressed Columns" in the specification)

Definition at line 266 of file RNTupleDescriptor.hxx.

fNElements

ROOT::NTupleSize_t ROOT::RClusterDescriptor::RColumnRange::fNElements = ROOT::kInvalidNTupleIndex

private

The number of column elements in the cluster.

Definition at line 258 of file RNTupleDescriptor.hxx.

fPhysicalColumnId

ROOT::DescriptorId_t ROOT::RClusterDescriptor::RColumnRange::fPhysicalColumnId = ROOT::kInvalidDescriptorId

private

Definition at line 254 of file RNTupleDescriptor.hxx.
