Member Function Documentation

virtual double JAANET::JEvtWeight::getNormalisation ( ) const

inlineoverridevirtual

Get event-weight normalisation.

Note: the return-value should be multiplied in order to normalise the event-weight

Returns

event-weight normalisation

Implements JAANET::JEvtWeightInterface.

Definition at line 52 of file JEvtWeight.hh.

    {
      return norm;
    }

virtual double JAANET::JEvtWeight::getNormalisation ( const Evt &  evt ) const

inlinevirtual

Get event-weight normalisation.

Note: the return-value should be multiplied in order to normalise the event-weight

Parameters

evt

event

Returns

event-weight normalisation

Definition at line 65 of file JEvtWeight.hh.

    {
      return (evt.w.size() > WEIGHTLIST_NORMALISATION &&
              evt.w[WEIGHTLIST_NORMALISATION] > 0.0 ?
              evt.w[WEIGHTLIST_NORMALISATION] : norm);
    }

virtual void JAANET::JEvtWeightInterface::configure ( const JHead &  header )

pure virtualinherited

Configuration.

Parameters

header

header

virtual bool JAANET::JEvtWeightInterface::check ( const JHead &  header ) const

pure virtualinherited

Check whether header is consistent with this event weighter.

Parameters

header

header

Returns

true if consistent; else false

virtual double JAANET::JEvtWeightInterface::getWeight ( const Evt &  evt ) const

pure virtualinherited

Get weight of given event.

Parameters

evt

event

Returns

weight [Hz]

template<class JClonable_t, class JDerived_t = JNullType>

virtual clone_type JLANG::JClonable< JClonable_t, JDerived_t >::clone ( ) const

inlineoverridevirtualinherited

Get clone of this object.

Returns

pointer to newly created object
