ROOT::Detail::RDF::RJittedDefine Class Reference

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.

Definition at line 31 of file RJittedDefine.cxx.

◆ GetValuePtr()

void * RJittedDefine::GetValuePtr ( unsigned int  slot)
finalvirtual

Return the (type-erased) address of the Define'd value for the given processing slot.

Implements ROOT::Detail::RDF::RDefineBase.

Definition at line 25 of file RJittedDefine.cxx.

◆ GetVariedDefine()

RDefineBase & RJittedDefine::GetVariedDefine ( const std::string &  variationName)
finalvirtual

Return a clone of this Define that works with values in the variationName "universe".

Implements ROOT::Detail::RDF::RDefineBase.

Definition at line 66 of file RJittedDefine.cxx.

◆ InitSlot()

void RJittedDefine::InitSlot ( TTreeReader r,
unsigned int  slot 
)
finalvirtual

Implements ROOT::Detail::RDF::RDefineBase.

Definition at line 19 of file RJittedDefine.cxx.

◆ MakeVariations()

void RJittedDefine::MakeVariations ( const std::vector< std::string > &  variations)
finalvirtual

Create clones of this Define that work with values in varied "universes".

Implements ROOT::Detail::RDF::RDefineBase.

Definition at line 60 of file RJittedDefine.cxx.

◆ SetDefine()

void ROOT::Detail::RDF::RJittedDefine::SetDefine ( std::unique_ptr< RDefineBase c)
inline

Definition at line 56 of file RJittedDefine.hxx.

◆ 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 48 of file RJittedDefine.cxx.

◆ Update() [2/2]

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

Update the value at the address returned by GetValuePtr with the content corresponding to the given entry.

Implements ROOT::Detail::RDF::RDefineBase.

Definition at line 42 of file RJittedDefine.cxx.

Member Data Documentation

◆ fConcreteDefine

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

Definition at line 37 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.
