Enumeration Type Documentation

◆ ENTupleMergeErrBehavior

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

strong

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 57 of file RNTupleMerger.hxx.

◆ ENTupleMergeVersionBehavior

enum class ROOT::Experimental::Internal::ENTupleMergeVersionBehavior

strong

Enumerator

kWarnOnHigherVersion

The merger will emit a warning when merging RNTuples with higher version than the latest supported by this ROOT version, but merging will work.

Some optional features present in the source(s) may be missing from the merged RNTuple.

kAbortOnHigherVersion

The merger will refuse to merge RNTuples with higher versions than the latest supported by this ROOT version.

The merging process will abort as soon as one such source is encountered.

Definition at line 64 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.
