◆ FieldIndex_t

using ROOT::Experimental::Internal::RNTupleProcessorEntry::FieldIndex_t = std::uint64_t

Definition at line 94 of file RNTupleProcessorEntry.hxx.

Member Function Documentation

◆ AddField()

ROOT::Experimental::Internal::RNTupleProcessorEntry::FieldIndex_t ROOT::Experimental::Internal::RNTupleProcessorEntry::AddField	(	const std::string &	qualifiedFieldName,
		std::unique_ptr< ROOT::RFieldBase >	field,
		void *	valuePtr,
		const RNTupleProcessorProvenance &	provenance )

Add a new field to the entry.

Parameters

[in]	qualifiedFieldName	Name of the field to add, including its parent field if applicable.
[in]	field	Reference to the field to add, used to to create its corresponding RValue.
[in]	valuePtr	Pointer to an object corresponding to the field's type to bind to its value. If this is a `nullptr`, a pointer will be created.
[in]	provenance	Processor provenance of the field.

Returns: The field index of the newly added field.

Definition at line 55 of file RNTupleProcessorEntry.cxx.

◆ BindRawPtr()

void ROOT::Experimental::Internal::RNTupleProcessorEntry::BindRawPtr	(	FieldIndex_t	fieldIdx,
		void *	valuePtr )

Parameters

[in]	fieldIdx	The index of the field in the entry.
[in]	valuePtr	Pointer to the value to bind to the field.

Definition at line 98 of file RNTupleProcessorEntry.cxx.

Find the field index of the provided field in the entry.

Parameters

[in] canonicalFieldName The name of the field in the entry, including its processor name prefixes and parent field names, if applicable.

Returns: A std::optional containing the field index if it was found.

Definition at line 34 of file RNTupleProcessorEntry.cxx.

◆ FindFieldName()

const std::string & ROOT::Experimental::Internal::RNTupleProcessorEntry::FindFieldName ( FieldIndex_t fieldIdx ) const
