Constructor & Destructor Documentation

◆ TTreeReaderValueFast()

template<typename T>

◆ Adjust()

virtual Int_t ROOT::Experimental::Internal::TTreeReaderValueFastBase::Adjust ( Int_t eventCount)
inlineprotectedvirtualinherited

Definition at line 93 of file TTreeReaderValueFast.hxx.

◆ BranchTypeName()

virtual const char * ROOT::Experimental::Internal::TTreeReaderValueFastBase::BranchTypeName ( )
protectedpure virtualinherited

Implemented in ROOT::Experimental::TTreeReaderValueFast< bool >, ROOT::Experimental::TTreeReaderValueFast< double >, ROOT::Experimental::TTreeReaderValueFast< float >, ROOT::Experimental::TTreeReaderValueFast< Int_t >, and ROOT::Experimental::TTreeReaderValueFast< UInt_t >.

◆ CreateProxy()

void ROOT::Experimental::Internal::TTreeReaderValueFastBase::CreateProxy ( )
protectedinherited

Attach this value to the appropriate branch on the tree.

For now, we don't support the complex branch lookup of the TTreeReader – only a fixed leaf!
