ROOT::Experimental::Internal::RNTupleMergeOptions Struct Reference

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.ExtraVerbose" -> sets fExtraVerbose to true Rules about the string-based options:
  1. there must be no space between the separators (i.e. . and =)
  2. all string matching is case insensitive

◆ 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 73 of file RNTupleMerger.hxx.

◆ fErrBehavior

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

Determines how the Merge function behaves upon merging errors.

Definition at line 77 of file RNTupleMerger.hxx.

◆ fExtraVerbose

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

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

Definition at line 79 of file RNTupleMerger.hxx.

◆ fMergingMode

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

Determines how the merging treats sources with different models (.
