class RooNumGenFactory: public TObject

RooNumGenFactory is a factory to instantiate numeric integrators from a given function binding and a given configuration. The factory searches for a numeric integrator registered with the factory that has the ability to perform the numeric integration. The choice of method may depend on the number of dimensions integrated, the nature of the integration limits (closed or open ended) and the preference of the caller as encoded in the configuration object.

Function documentation

RooNumGenFactory()

 Constructor. Register all known integrators by calling
 their static registration functions

~RooNumGenFactory()

 Destructor

RooNumGenFactory(const RooNumGenFactory& other)

 Copy constructor

RooNumGenFactory& instance()

 Static method returning reference to singleton instance of factory

void cleanup()

 Cleanup routine called by atexit() handler installed by RooSentinel

Bool_t storeProtoSampler(RooAbsNumGenerator* proto, const RooArgSet& defConfig)

 Method accepting registration of a prototype numeric integrator along with a RooArgSet of its
 default configuration options and an optional list of names of other numeric integrators
 on which this integrator depends. Returns true if integrator was previously registered

const RooAbsNumGenerator* getProtoSampler(const char* name)

 Return prototype integrator with given (class) name

RooAbsNumGenerator* createSampler(RooAbsReal& func, const RooArgSet& genVars, const RooArgSet& condVars, const RooNumGenConfig& config, Bool_t verbose = kFALSE, RooAbsReal* maxFuncVal = 0)

 Construct a numeric integrator instance that operates on function 'func' and is configured
 with 'config'. If ndimPreset is greater than zero that number is taken as the dimensionality
 of the integration, otherwise it is queried from 'func'. This function iterators over list
 of available prototype integrators and returns an clone attached to the given function of
 the first class that matches the specifications of the requested integration considering
 the number of dimensions, the nature of the limits (open ended vs closed) and the user
 preference stated in 'config'
