Member Typedef Documentation

◆ FieldIndex_t

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

Definition at line 95 of file RNTupleProcessorEntry.hxx.

Member Function Documentation

◆ AddField()

FieldIndex_t ROOT::Experimental::Internal::RNTupleProcessorEntry::AddField	(	std::string_view	fieldName,
		ROOT::RFieldBase &	field,
		void *	valuePtr,
		const RNTupleProcessorProvenance &	provenance )

inline

Add a new field to the entry.

Parameters

[in]	fieldName	Name of the field to add.
[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 180 of file RNTupleProcessorEntry.hxx.

◆ BindRawPtr()

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

inline

Bind a new value pointer to a field in the entry.

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 217 of file RNTupleProcessorEntry.hxx.

◆ FindFieldIndex()

std::optional< FieldIndex_t > ROOT::Experimental::Internal::RNTupleProcessorEntry::FindFieldIndex ( std::string_view fieldName ) const
