Member Function Documentation

EgammaTrackSelector::result_type EgammaTrackSelector::operator()

(

const input_type &

tracks

)

const

pick/read variables in order to cut down on unnecessary calls someone will have some fun reading the log if Debug is on the biggest reason is the numberOfValidHits call (the rest are not as costly)

access to the remaining vars is slow

skip if min Hits == 0; assumes any track has at least one valid hit

similarly here
