Set of merging options to pass to RNTupleMerger.

If you're using the merger through TFileMerger you need to give it string-based options instead. Here is the mapping for the TFileMerger options:

"rntuple.MergingMode=(Filter|Union|...)" -> sets fMergingMode
"rntuple.ErrBehavior=(Abort|Skip|...)" -> sets fErrBehavior
"rntuple.VersionBehavior=(WarnOnHigherVersion|AbortOnHigherVersion|...)" -> sets fVersionBehavior
"rntuple.ExtraVerbose" -> sets fExtraVerbose to true Rules about the string-based options:

◆ fCompressionSettings

std::optional<std::uint32_t> ROOT::Experimental::Internal::RNTupleMergeOptions::fCompressionSettings

If fCompressionSettings is empty (the default), the merger will not change the compression of any of its sources (fast merging).

Otherwise, all sources will be converted to the specified compression algorithm and level.

Definition at line 92 of file RNTupleMerger.hxx.

ENTupleMergeErrBehavior ROOT::Experimental::Internal::RNTupleMergeOptions::fErrBehavior = ENTupleMergeErrBehavior::kAbort

Determines how the Merge function behaves upon merging errors.

Definition at line 96 of file RNTupleMerger.hxx.

bool ROOT::Experimental::Internal::RNTupleMergeOptions::fExtraVerbose = false

If true, the merger will emit further diagnostics and information.

ENTupleMergingMode ROOT::Experimental::Internal::RNTupleMergeOptions::fMergingMode = ENTupleMergingMode::kFilter

Determines how the merging treats sources with different models (.

Definition at line 94 of file RNTupleMerger.hxx.

Determines how the Merge function behaves depending on the RNTuple sources' version.
