Detailed Description

template<class JEvtWeightFactor_t>
struct JAANET::JEvtWeightFactorMultiParticle< JEvtWeightFactor_t >

Implementation of event-weight factor for multiple particle types.

The first template argument corresponds to the type of event-weight factor class. This class must contain the method getFactor(const Evt&). The second template argument refers to the helper-class to the event-weight factor of the type of the first template argument.
