Member RooAbsCategory::defineType (const char *label)

Use defineState(const std::string& label)

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

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

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

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

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::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 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::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 RooFit::Optimize (Int_t flag=2)

Has no effect anymore. Functionality was removed in ROOT 6.42, and this function is kept as an empty shell that does nothing (for API compatibility between different ROOT versions).

Member RooMinimizer::optimizeConst (int flag)

Has no effect anymore. Functionality was removed in ROOT 6.42, and this function is kept as an empty shell that does nothing (for API compatibility between different ROOT versions).

Member RooRealProxy

Use RooTemplateProxy<RooAbsReal> or more appropriate template parameters.

Member RooStats::IsNLLOffset ()

Use NLLOffsetMode().

Member RooStats::UseNLLOffset (bool on)

Use SetNLLOffsetMode().

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.

This flag has no effect in ROOT.

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

Member TH1::AddDirectory (Bool_t add=kTRUE)

Use ROOT::Experimental::ObjectAutoRegistrationEnabled(). It can be set using an entry in rootrc or an environment variable, is initialised in a thread-safe manner and covers more cases.

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

Use signature with std::string
