Detailed Description

template<typename T, int Tid>
class HLTSmartSinglet< T, Tid >

This class is an HLTFilter (-> EDFilter) implementing a smart HLT trigger cut, specified as a string such as "pt>15 && -3<eta<3", for single objects of the same physics type, allowing to cut on variables relating to both the base class T and the derived actual class
