## Class Description

     This class holds in addition a unit and label string, as well
     as a plot range and number of plot bins and plot creation methods.

~RooAbsReal()

TString getTitle(Bool_t appendUnit) const

     Return this variable's title string. If appendUnit is true and
     this variable has units, also append a string " (<unit>)".

Double_t getVal(const RooArgSet* set) const

     Return value of object. Calculated if dirty, otherwise cached value is returned.

Double_t traceEval(const RooArgSet* /*nset*/) const

     Calculate current value of object, with error tracing wrapper

Int_t getAnalyticalIntegralWN(RooArgSet& allDeps, RooArgSet& analDeps, const RooArgSet* /*normSet*/, const char* rangeName) const

     Default implementation of getAnalyticalIntegralWN for real valued objects defers to
     normalization invariant getAnalyticalIntegral()

Int_t getAnalyticalIntegral(RooArgSet& /*allDeps*/, RooArgSet& /*analDeps*/, const char* /*rangeName*/) const

     By default we do not supply any analytical integrals

Double_t analyticalIntegralWN(Int_t code, const RooArgSet* normSet, const char* rangeName) const

     Default implementation of analyticalIntegralWN handles only the pass-through
     scenario (code =0). All other codes are deferred to to the normalization
     invariant analyticalIntegral()

Double_t analyticalIntegral(Int_t code, const char* /*rangeName*/) const

     By default no analytical integrals are implemented

const char* getPlotLabel() const

     Get the label associated with the variable

void setPlotLabel(const char *label)

     Set the label associated with this variable

Bool_t readFromStream(istream& /*is*/, Bool_t /*compact*/, Bool_t /*verbose*/)

    Read object contents from stream (dummy for now)

void writeToStream(ostream& /*os*/, Bool_t /*compact*/) const

    Write object contents to stream (dummy for now)

void printToStream(ostream& os, PrintOption opt, TString indent) const

     Print info about this object to the specified stream. In addition to the info
     from RooAbsArg::printToStream() we add:

         Shape : value, units, plot range
       Verbose : default binning and print label

void setPlotMin(Double_t value)

     Set minimum value of output associated with this object

void setPlotMax(Double_t value)

     Set maximum value of output associated with this object

void setPlotRange(Double_t, Double_t)

     Set a new plot range

void setPlotBins(Int_t /*value*/)

     Set number of histogram bins

Bool_t inPlotRange(Double_t value) const

     Check if given value is in the min-max range for this object

Bool_t isValid() const

     Check if current value is valid

Bool_t isValidReal(Double_t /*value*/, Bool_t /*printError*/) const

     Check if given value is valid

RooAbsReal* createIntegral(const RooArgSet& iset, const RooCmdArg arg1, const RooCmdArg arg2, const RooCmdArg arg3, const RooCmdArg arg4, const RooCmdArg arg5, const RooCmdArg arg6, const RooCmdArg arg7, const RooCmdArg arg8) const

     Create an object that represents the integral of the function over one or more observables listed in iset
     The actual integration calculation is only performed when the return object is evaluated. The name
     of the integral object is automatically constructed from the name of the input function, the variables
     it integrates and the range integrates over

     The following named arguments are accepted

     NormSet(const RooArgSet&)            -- Specify normalization set, mostly useful when working with PDFS
     NumIntConfig(const RooNumIntConfig&) -- Use given configuration for any numeric integration, if necessary
     Range(const char* name)              -- Integrate only over given range. Multiple ranges may be specified
                                             by passing multiple Range() arguments

RooAbsReal* createIntegral(const RooArgSet& iset, const RooArgSet* nset, const RooNumIntConfig* cfg, const char* rangeName) const

TString integralNameSuffix(const RooArgSet& iset, const RooArgSet* nset, const char* rangeName) const

const RooAbsReal* createProjection(const RooArgSet& depVars, const RooArgSet& projVars, RooArgSet*& cloneSet) const

const RooAbsReal* createProjection(const RooArgSet& depVars, const RooArgSet& projVars) const

const RooAbsReal* createProjection(const RooArgSet &dependentVars, const RooArgSet *projectedVars, RooArgSet *&cloneSet, const char* rangeName) const

     Create a new object G that represents the normalized projection:

                 Integral [ F[x,y,p] , { y } ]
      G[x,p] = ---------------------------------
                Integral [ F[x,y,p] , { x,y } ]

     where F[x,y,p] is the function we represent, "x" are the
     specified dependentVars, "y" are the specified projectedVars, and
     "p" are our remaining variables ("parameters"). Return a
     pointer to the newly created object, or else zero in case of an
     error.  The caller is responsible for deleting the contents of
     cloneSet (which includes the returned projection object) whatever
     the return value. Note that you should normally call getVal()
     on the returned object, without providing any set of normalization
     variables. Otherwise you are requesting an additional normalization
     beyond what is already specified in the equation above.

TH1* fillHistogram(TH1 *hist, const RooArgList &plotVars, Double_t scaleFactor, const RooArgSet *projectedVars) const

     Loop over the bins of the input histogram and add an amount equal to our value evaluated
     at the bin center to each one. Our value is calculated by first integrating out any variables
     in projectedVars and then scaling the result by scaleFactor. Returns a pointer to the
     input histogram, or zero in case of an error. The input histogram can be any TH1 subclass, and
     therefore of arbitrary dimension. Variables are matched with the (x,y,...) dimensions of the input
     histogram according to the order in which they appear in the input plotVars list.

TH1* createHistogram(const char *name, const RooAbsRealLValue& xvar, const RooCmdArg& arg1, const RooCmdArg& arg2, const RooCmdArg& arg3, const RooCmdArg& arg4, const RooCmdArg& arg5, const RooCmdArg& arg6, const RooCmdArg& arg7, const RooCmdArg& arg8) const

     Create and fill a ROOT histogram TH1,TH2 or TH3 with the values of this function.

     This function accepts the following arguments

     name -- Name of the ROOT histogram
     xvar -- Observable to be mapped on x axis of ROOT histogram

     Binning(const char* name)                    -- Apply binning with given name to x axis of histogram
     Binning(RooAbsBinning& binning)              -- Apply specified binning to x axis of histogram
     Binning(double lo, double hi, int nbins)     -- Apply specified binning to x axis of histogram
     ConditionalObservables(const RooArgSet& set) -- Do not normalized PDF over following observables when projecting PDF into histogram

     YVar(const RooAbsRealLValue& var,...)    -- Observable to be mapped on y axis of ROOT histogram
     ZVar(const RooAbsRealLValue& var,...)    -- Observable to be mapped on z axis of ROOT histogram

     The YVar() and ZVar() arguments can be supplied with optional Binning() arguments to control the binning of the Y and Z axes, e.g.
     createHistogram("histo",x,Binning(-1,1,20), YVar(y,Binning(-1,1,30)), ZVar(z,Binning("zbinning")))

     The caller takes ownership of the returned histogram

RooPlot* plotOn(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, const RooCmdArg& arg9, const RooCmdArg& arg10) const

     Plot (project) PDF on specified frame. If a PDF is plotted in an empty frame, it
     will show a unit normalized curve in the frame variable, taken at the present value
     of other observables defined for this PDF

     If a PDF is plotted in a frame in which a dataset has already been plotted, it will
     show a projected curve integrated over all variables that were present in the shown
     dataset except for the one on the x-axis. The normalization of the curve will also
     be adjusted to the event count of the plotted dataset. An informational message
     will be printed for each projection step that is performed

     This function takes the following named arguments

     Projection control
     ------------------
     Slice(const RooArgSet& set)     -- Override default projection behaviour by omittting observables listed
                                        in set from the projection, resulting a 'slice' plot. Slicing is usually
                                        only sensible in discrete observables
     Project(const RooArgSet& set)   -- Override default projection behaviour by projecting over observables
                                        given in set and complete ignoring the default projection behavior. Advanced use only.
     ProjWData(const RooAbsData& d)  -- Override default projection _technique_ (integration). For observables present in given dataset
                                        projection of PDF is achieved by constructing an average over all observable values in given set.
                                        Consult RooFit plotting tutorial for further explanation of meaning & use of this technique
     ProjWData(const RooArgSet& s,   -- As above but only consider subset 's' of observables in dataset 'd' for projection through data averaging
               const RooAbsData& d)
     ProjectionRange(const char* rn) -- Override default range of projection integrals to a different range speficied by given range name.
                                        This technique allows you to project a finite width slice in a real-valued observable

     Misc content control
     --------------------
     Normalization(Double_t scale,   -- Adjust normalization by given scale factor. Interpretation of number depends on code: Relative:
                    ScaleType code)     relative adjustment factor, NumEvent: scale to match given number of events.
     Name(const chat* name)          -- Give curve specified name in frame. Useful if curve is to be referenced later
     Asymmetry(const RooCategory& c) -- Show the asymmetry of the PDF in given two-state category [F(+)-F(-)] / [F(+)+F(-)] rather than
                                        the PDF projection. Category must have two states with indices -1 and +1 or three states with
                                        indeces -1,0 and +1.
     ShiftToZero(Bool_t flag)        -- Shift entire curve such that lowest visible point is at exactly zero. Mostly useful when

RooPlot* plotOn(RooPlot* frame, RooLinkedList& argList) const

RooPlot* plotOn(RooPlot *frame, PlotOpt o) const

     Plot ourselves on given frame. If frame contains a histogram, all dimensions of the plotted
     function that occur in the previously plotted dataset are projected via partial integration,
     otherwise no projections are performed. Optionally, certain projections can be performed
     by summing over the values present in a provided dataset ('projData'), to correctly
     project out data dependents that are not properly described by the PDF (e.g. per-event errors).

     The functions value can be multiplied with an optional scale factor. The interpretation
     of the scale factor is unique for generic real functions, for PDFs there are various interpretations
     possible, which can be selection with 'stype' (see RooAbsPdf::plotOn() for details).

     The default projection behaviour can be overriden by supplying an optional set of dependents
     to project. For most cases, plotSliceOn() and plotProjOn() provide a more intuitive interface
     to modify the default projection behavour.

RooPlot* plotSliceOn(RooPlot *frame, const RooArgSet& sliceSet, Option_t* drawOptions, Double_t scaleFactor, ScaleType stype, const RooAbsData* projData) const

     Plot ourselves on given frame, as done in plotOn(), except that the variables
     listed in 'sliceSet' are taken out from the default list of projected dimensions created
     by plotOn().

RooPlot* plotAsymOn(RooPlot *frame, const RooAbsCategoryLValue& asymCat, PlotOpt o) const

     Plot asymmetry of ourselves, defined as

       asym = f(asymCat=-1) - f(asymCat=+1) / ( f(asymCat=-1) + f(asymCat=+1) )

     on frame. If frame contains a histogram, all dimensions of the plotted
     asymmetry function that occur in the previously plotted dataset are projected via partial integration.
     Otherwise no projections are performed,

     The asymmetry function can be multiplied with an optional scale factor. The default projection
     behaviour can be overriden by supplying an optional set of dependents to project.

Bool_t plotSanityChecks(RooPlot* frame) const

     Perform general sanity check on frame to ensure safe plotting operations

void makeProjectionSet(const RooAbsArg* plotVar, const RooArgSet* allVars, RooArgSet& projectedVars, Bool_t silent) const

     Construct the set of dependents to project when plotting ourselves as function
     of 'plotVar'. 'allVars' is the list of variables that must be projected, but
     may contain variables that we do not depend on. If 'silent' is cleared,
     warnings about inconsistent input parameters will be printed.

RooAbsFunc* bindVars(const RooArgSet &vars, const RooArgSet* nset, Bool_t clipInvalid) const

     Create an interface adaptor f(vars) that binds us to the specified variables
     (in arbitrary order). For example, calling bindVars({x1,x3}) on an object
     F(x1,x2,x3,x4) returns an object f(x1,x3) that is evaluated using the
     current values of x2 and x4. The caller takes ownership of the returned adaptor.

void copyCache(const RooAbsArg* source)

     Copy the cached value of another RooAbsArg to our cache

void attachToTree(TTree& t, Int_t bufSize)

     Attach object to a branch of given TTree

void fillTreeBranch(TTree& t)

     Attach object to a branch of given TTree

void setTreeBranchStatus(TTree& t, Bool_t active)

     (De)Activate associate tree branch

RooAbsArg* createFundamental(const char* newname) const

     Create a RooRealVar fundamental object with our properties. The new
     object will be created without any fit limits.

Bool_t matchArgs(const RooArgSet& allDeps, RooArgSet& analDeps, const RooArgSet& set) const

     Wrapper function for matchArgsByName()

Bool_t matchArgsByName(const RooArgSet &allArgs, RooArgSet &matchedArgs, const TList &nameList) const

     Check if allArgs contains matching elements for each name in nameList. If it does,
     add the corresponding args from allArgs to matchedArgs and return kTRUE. Otherwise
     return kFALSE and do not change matchedArgs.

Int_t getMaxVal(const RooArgSet& /*vars*/) const // Advertise capability to determine maximum value of function for given set of // observables. If no direct generator method is provided, this information // will assist the accept/reject generator to operate more efficiently as // it can skip the initial trial sampling phase to empirically find the function // maximum

Double_t maxVal(Int_t /*code*/)

     Return maximum value for set of observables identified by code assigned
     in getMaxVal
