◆ GetSampleCallback()

ROOT::RDF::SampleCallback_t ROOT::Internal::RDF::UntypedSnapshotTTreeHelperMT::GetSampleCallback ( )
inlinefinalvirtual

Override this method to register a callback that is executed before the processing a new data sample starts.

The callback will be invoked in the same conditions as with DefinePerSample().

Reimplemented from ROOT::Detail::RDF::RActionImpl< UntypedSnapshotTTreeHelperMT >.

◆ Initialize()

void ROOT::Internal::RDF::UntypedSnapshotTTreeHelperMT::Initialize ( )

Definition at line 775 of file RDFSnapshotHelpers.cxx.

◆ InitTask()

void ROOT::Internal::RDF::UntypedSnapshotTTreeHelperMT::InitTask ( TTreeReader * r,
unsigned int slot )

Definition at line 674 of file RDFSnapshotHelpers.cxx.

◆ MakeNew()

ROOT::Internal::RDF::UntypedSnapshotTTreeHelperMT ROOT::Internal::RDF::UntypedSnapshotTTreeHelperMT::MakeNew ( void * newName,
std::string_view = "nominal" )

Create a new UntypedSnapshotTTreeHelperMT with a different output file name.

Parameters
newNameA type-erased string with the output file name
Returns
UntypedSnapshotTTreeHelperMT

This MakeNew implementation is tied to the cloning feature of actions of the computation graph. In particular, cloning a Snapshot node usually also involves changing the name of the output file, otherwise the cloned Snapshot would overwrite the same file.
