Detailed Description

template<typename T>
class PdgIdFilter< T >

PdgIdFilter selects particles from their pdg id code.

Up to now, it is based on a ParticleCandidateList but it is very likely that internally it will be based on DecayPattern See AnalysisExamples/FilterExample.cxx for a concrete example

Member Function Documentation

isAccepted()

template<typename T>

bool PdgIdFilter< T >::isAccepted ( const T * element ) const

virtual

Main filter method.

This method takes the decision whether or not the filter has to accept the element. It returns true or false accordingly if the particle's id matches one of the required one.

Check if a pdg-id set has been set-up

Otherwise return true by convention

Implements IFilter< T >.

  if ( false == m_pdgIds.empty() ) {
    const int pdgId = element->pdgId();

    //m_pdgIds.dropList();
    if ( m_pdgIds.hasInList( pdgId, m_matchSign ) ) return true;
    else return false;
  }

  return true;
}

matchSign()

template<typename T>

bool PdgIdFilter< T >::matchSign ( ) const

inline

Return true if the filter requires a strict sign matching.

pdgIds()

template<typename T>

const ParticleCandidateList * PdgIdFilter< T >::pdgIds ( ) const

inline

Return the list of pdg ids the filter is looking for.

Definition at line 166 of file PdgIdFilter.h.

{
  return &m_pdgIds;
}

setFilter()

template<typename T>

void PdgIdFilter< T >::setFilter ( const IFilterCuts * ifilter )

virtual

Pure virtual function (to be overloaded by each of the children classes) to copy the cut properties of a given filter to another one.

It copies the properties of ifilter to the current IFilterCuts object.

Parameters

ifilter

the IFilterCuts which holds a set of properties one wants to copy to the current IFilterCuts object.

Implements IFilterCuts.
