Function documentation

RooSimGenContext(const RooSimultaneous& model, const RooArgSet& vars, const RooDataSet* prototype = 0, const RooArgSet* auxProto = 0, Bool_t _verbose = kFALSE)

 Constructor of specialized generator context for RooSimultaneous p.d.f.s. This
 context creates a dedicated context for each component p.d.f.s and delegates
 generation of events to the appropriate component generator context

~RooSimGenContext()

 Destructor. Delete all owned subgenerator contexts

void attach(const RooArgSet& params)

 Attach the index category clone to the given event buffer

void initGenerator(const RooArgSet& theEvent)

 Perform one-time initialization of generator context

RooDataSet* createDataSet(const char* name, const char* title, const RooArgSet& obs)

 Create an empty dataset to hold the events that will be generated

void generateEvent(RooArgSet& theEvent, Int_t remaining)

 Generate event appropriate for current index state.
 The index state is taken either from the prototype
 or is generated from the fraction threshold table.

void updateFractions()

 No action needed if we have a proto index

void setProtoDataOrder(Int_t* lut)

 Set the traversal order of the prototype data to that in the
 given lookup table. This information is passed to all
 component generator contexts

void printMultiline(ostream& os, Int_t content, Bool_t verbose = kFALSE, TString indent = "") const
