Detailed Description

template<typename T>
class pat::MatcherByPulls< T >

Description: Matches RecoCandidates to (Gen)Particles by looking at the pulls fo the track parameters. Produces as output an edm::Association to GenParticles, and a ValueMap with the pull values.

Implementation: uses MatcherByPullsAlgorithm the module is in the pat namespace, but it doesn't have any PAT dependency.
