RooNumGenFactory Class Reference

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.

◆ createSampler()

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'
