Weight_h ComputeWeight (const ToyExperiment &toy, const AnaEventC &event, const ToyBoxB &box)
 
- Public Member Functions inherited from EventWeightBase
 EventWeightBase ()
 Create the systematic, with one parameter.
 
 EventWeightBase (UInt_t npar)
 Create the systematic, specifying the number of systematic parameters.

§ ComputeWeight()

Weight_h P0DVetoSystematics::ComputeWeight ( const ToyExperiment &  toy,
const AnaEventC &  event,
const ToyBoxB &  box 
)
virtual

This is now the actual method called by SystematicManager, which allows further selection tunning of relevant objects once the ToyBox is filled This MUST be overridden in the derived class.

Implements EventWeightBase.
