Member RooAbsCategory::defineType (const char *label, int index)

Use defineState(const std::string& label, value_type index)

Member RooAbsCategory::defineType (const char *label)

Use defineState(const std::string& label)

Member RooAbsCategory::defineTypeUnchecked (const char *label, value_type index)

Use defineStateUnchecked(const std::string& label, value_type index)

Member RooAbsCategory::lookupType (const char *label, bool printError=false) const

RooCatType is not used, any more. This function will create one and let it leak. Use lookupIndex() (preferred) or lookupName() instead.

Member RooAbsCategory::lookupType (value_type index, bool printError=false) const

RooCatType is not used, any more. This function will create one and let it leak. Use lookupIndex() (preferred) or lookupName() instead.

Member RooAbsCategory::lookupType (const RooCatType &type, bool printError=false) const

RooCatType is not used, any more. This function will create one and let it leak. Use lookupIndex() (preferred) or lookupName() instead.

Member RooAbsCategory::typeIterator () const

Use begin() and end() instead.

Class RooAbsCategoryLegacyIterator

Legacy class to iterate through legacy RooAbsCategory states. Use RooAbsCategory::begin(), RooAbsCategory::end() or range-based for loops instead.

Member RooAbsData::statOn (RooPlot *frame, const RooCmdArg &arg1={}, const RooCmdArg &arg2={}, const RooCmdArg &arg3={}, const RooCmdArg &arg4={}, const RooCmdArg &arg5={}, const RooCmdArg &arg6={}, const RooCmdArg &arg7={}, const RooCmdArg &arg8={})

Classing parameter formatting options, provided for backward compatibility

Member RooCategoryProxy

Use RooTemplateProxy<RooAbsCategory> or more appropriate template parameters.

Member RooDataHist::binVolume () const

Use binVolume(std::size_t) const.

Member RooDataHist::calcTreeIndex () const

Use calcTreeIndex(const RooArgSet&,bool) const.

Member RooDataHist::set (double wgt, double wgtErr=-1)

Use set(std::size_t,double,double)

Member RooDataHist::weight () const override

Use the safer weight(std::size_t) const.

Member RooDataHist::weightSquared () const override

Use the safer weightSquared(std::size_t) const.

Member RooRealProxy

Use RooTemplateProxy<RooAbsReal> or more appropriate template parameters.

Member RooStats::IsNLLOffset ()

Use NLLOffsetMode().

Member RooStats::UseNLLOffset (bool on)

Use SetNLLOffsetMode().

Member ROOT::RDF::RInterface< Proxied, DataSource >::R__DEPRECATED (6, 40, "Snapshot does not need template arguments anymore, you can safely remove them from this function call.") RResultPtr< RInterface< RLoopManager > > Snapshot(std

Use other overloads that do not require template arguments.

Member RooTemplateProxy< T >::lvptr (const LValue_t *) const

This function is unnecessary if the template parameter is RooAbsRealLValue (+ derived types) or RooAbsCategoryLValue (+derived types), as arg() will always return the correct type.

File RtypesCore.h

For future designs, unless for very specific needs, consider using instead standard fixed-width classes from <cstdint> such as std::int16_t, std::int32_t or from <cstdfloat> for floating types.

Member Short_t

Consider replacing with short or std::int16_t

Member TFitter::Chisquare (Int_t npar, Double_t *params) const override

Use ROOT::Fit::Chisquare class instead.

Class TGeoTrack

Use of TGeoTrack is deprecated. For the event display please switch to TEve (using TEveTracks or TEvePointSet to display tracks specifically) or to REve.

Class TH1K

The TH1K class is deprecated and will be removed in 6.40. It did not implement the TH1 interface consistently, and limited the usability of the k-neighbors method it implemented by closely coupling the algorithm with the histogram class. Please use the new TMath::KNNDensity function that implements the same mathematical logic.

Member THttpCallArg::SetPostData (void *data, Long_t length, Bool_t make_copy=kFALSE)

Use signature with std::string
