Member Data Documentation

◆ fCompressionSettings

int ROOT::Experimental::RClusterDescriptor::RColumnRange::fCompressionSettings = kUnknownCompressionSettings

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.

Definition at line 263 of file RNTupleDescriptor.hxx.

◆ fFirstElementIndex

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

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

Definition at line 258 of file RNTupleDescriptor.hxx.

◆ fIsSuppressed

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

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 267 of file RNTupleDescriptor.hxx.

◆ fNElements

ClusterSize_t ROOT::Experimental::RClusterDescriptor::RColumnRange::fNElements = kInvalidClusterIndex

The number of column elements in the cluster.

Definition at line 260 of file RNTupleDescriptor.hxx.

◆ fPhysicalColumnId

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

Definition at line 256 of file RNTupleDescriptor.hxx.
