Definition at line 1079 of file RLoopManager.cxx.

◆ ChangeSpec()

void RLoopManager::ChangeSpec ( ROOT::RDF::Experimental::RDatasetSpec &&  spec)

Changes the internal TTree held by the RLoopManager.

Warning
This method may lead to potentially dangerous interactions if used after the construction of the RDataFrame. Changing the specification makes sense if and only if the schema of the dataset is unchanged, i.e. the new specification refers to exactly the same number of columns, with the same names and types. The actual use case of this method is moving the processing of the same RDataFrame to a different range of entries of the same dataset (which may be stored in a different set of files).
Parameters
specThe specification of the dataset to be adopted.

◆ EvalChildrenCounts()

void RLoopManager::EvalChildrenCounts ( )
private

Trigger counting of number of children nodes for each node of the functional graph.

This is done once before starting the event loop. Each action sends an increase children count signal upstream, which is propagated until RLoopManager. Each time a node receives the signal, in increments its children counter. Each node only propagates the signal once, even if it receives it multiple times. Named filters also send an increase children count signal, just like actions, as they always execute during the event loop so the graph branch they belong to must count as active even if it does not end in an action.

◆ fLoopType

const ELoopType ROOT::Detail::RDF::RLoopManager::fLoopType
private

The kind of event loop that is going to be run (e.g. on ROOT files, on no files)

Definition at line 140 of file RLoopManager.hxx.

◆ fMustRunNamedFilters

bool ROOT::Detail::RDF::RLoopManager::fMustRunNamedFilters {true}
private

Definition at line 139 of file RLoopManager.hxx.

◆ fNewSampleNotifier

RDFInternal::RNewSampleNotifier ROOT::Detail::RDF::RLoopManager::fNewSampleNotifier
private

Definition at line 151 of file RLoopManager.hxx.

◆ fNoCleanupNotifier

ROOT::Internal::TreeUtils::RNoCleanupNotifier ROOT::Detail::RDF::RLoopManager::fNoCleanupNotifier
private

Definition at line 161 of file RLoopManager.hxx.

◆ fNRuns

unsigned int ROOT::Detail::RDF::RLoopManager::fNRuns {0}
private

Number of event loops run.

Definition at line 153 of file RLoopManager.hxx.

◆ fNSlots

const unsigned int ROOT::Detail::RDF::RLoopManager::fNSlots {1}
private

Definition at line 138 of file RLoopManager.hxx.

◆ fRunActions

std::vector<RDFInternal::RActionBase *> ROOT::Detail::RDF::RLoopManager::fRunActions
private

Non-owning pointers to actions already run.

Definition at line 115 of file RLoopManager.hxx.

◆ fSampleCallbacks

std::unordered_map<void *, ROOT::RDF::SampleCallback_t> ROOT::Detail::RDF::RLoopManager::fSampleCallbacks
private

Registered callbacks to call at the beginning of each "data block".

The key is the pointer of the corresponding node in the computation graph (a RDefinePerSample or a RAction).

Definition at line 150 of file RLoopManager.hxx.

◆ fSampleInfos

std::vector<ROOT::RDF::RSampleInfo> ROOT::Detail::RDF::RLoopManager::fSampleInfos
private

Definition at line 152 of file RLoopManager.hxx.

◆ fSampleMap

std::unordered_map<std::string, ROOT::RDF::Experimental::RSample *> ROOT::Detail::RDF::RLoopManager::fSampleMap
private

Keys are fname + "/" + treename as RSampleInfo::fID; Values are pointers to the corresponding sample.

Definition at line 129 of file RLoopManager.hxx.

◆ fSamples

std::vector<ROOT::RDF::Experimental::RSample> ROOT::Detail::RDF::RLoopManager::fSamples
private

Samples need to survive throughout the whole event loop, hence stored as an attribute.

Definition at line 131 of file RLoopManager.hxx.

◆ fTree

std::shared_ptr<TTree> ROOT::Detail::RDF::RLoopManager::fTree {nullptr}
private

Shared pointer to the input TTree.

It does not delete the pointee if the TTree/TChain was passed directly as an argument to RDataFrame's ctor (in which case we let users retain ownership).

Definition at line 124 of file RLoopManager.hxx.

◆ fValidBranchNames

ColumnNames_t ROOT::Detail::RDF::RLoopManager::fValidBranchNames
private

Cache of the tree/chain branch names. Never access directy, always use GetBranchNames().

Definition at line 159 of file RLoopManager.hxx.
