A wrapper around a concrete RDefine, which forwards all calls to it RJittedDefine is a placeholder that is put in the collection of custom columns in place of a RDefine that will be just-in-time compiled.

Jitted code will assign the concrete RDefine to this RJittedDefine before the event-loop starts.

◆ Update() [1/2]

void RJittedDefine::Update	(	unsigned int	,
		const ROOT::RDF::RSampleInfo &
	)

finalvirtual

Update function to be called once per sample, used if the derived type is a RDefinePerSample.

Reimplemented from ROOT::Detail::RDF::RDefineBase.

Definition at line 52 of file RJittedDefine.cxx.

◆ Update() [2/2]

void RJittedDefine::Update	(	unsigned int	slot,
		Long64_t	entry

Member Data Documentation

◆ fConcreteDefine

std::unique_ptr<RDefineBase> ROOT::Detail::RDF::RJittedDefine::fConcreteDefine = nullptr

private

Definition at line 34 of file RJittedDefine.hxx.

◆ fTypeId

const std::type_info* ROOT::Detail::RDF::RJittedDefine::fTypeId = nullptr

private

Type info obtained through TypeName2TypeID based on the column type name.

The expectation is that this always compares equal to fConcreteDefine->GetTypeId() (which however is only available after jitting). It can be null if TypeName2TypeID failed to figure out this type.
