Detailed Description

template<class OrigMap, class CmpT = std::less<typename OrigMap::mapped_type>>
class Trk::InverseMultiMap< OrigMap, CmpT >

An InverseMultiMap object built from a generic map or multimap allows for quick lookup of original (multi)map's key by original mapped value.

Example of use:

#include "TrkEventUtils/InverseMultiMap.h"
 
...
 
PRD_MultiTruthCollection *origMap = ...; // retrieve from the SG
 
Trk::InverseMultiMap<PRD_MultiTruthCollection> invMap;
 
Trk::addToInverseMultiMap(&invMap, *origMap);
