◆ ENTupleMergeErrBehavior

enum class ROOT::Experimental::Internal::ENTupleMergeErrBehavior

Enumerator
kAbort	The merger will abort merging as soon as an error is encountered.
kSkip	Upon errors, the merger will skip the current source and continue.

Definition at line 58 of file RNTupleMerger.hxx.

◆ ENTupleMergingMode

enum class ROOT::Experimental::Internal::ENTupleMergingMode

strong

Enumerator

kFilter

The merger will discard all columns that aren't present in the prototype model (i.e.

the model of the first source); also all subsequent RNTuples must contain at least all the columns that are present in the prototype model

kStrict

The merger will refuse to merge any 2 RNTuples whose schema doesn't match exactly.

kUnion

The merger will update the output model to include all columns from all sources.

Entries corresponding to columns that are not present in a source will be set to the default value of the type.

Definition at line 40 of file RNTupleMerger.hxx.

Function Documentation

◆ CreateBinIndexRange()

RBinIndexRange ROOT::Experimental::Internal::CreateBinIndexRange	(	RBinIndex	begin,
		RBinIndex	end,
		std::size_t	nNormalBins )

Internal function to create RBinIndexRange.

Users are strongly advised to create bin index ranges via the respective axis types, for example with RRegularAxis::GetNormalRange(RBinIndex, RBinIndex) or RRegularAxis::GetFullRange().

Parameters

[in]	begin	the begin of the bin index range (inclusive)
[in]	end	the end of the bin index range (exclusive)
[in]	nNormalBins	the number of normal bins, after which iteration advances to RBinIndex::Overflow()

Definition at line 133 of file RBinIndexRange.hxx.

std::ostream & ROOT::Experimental::Internal::operator<<	(	std::ostream &	os,
		const std::optional< ROOT::RColumnDescriptor::RValueRange > &	x )

◆ ToString()

const char * ROOT::Experimental::Internal::ToString ( ENTupleMergingMode mode )
