Detailed Description

template<typename C>
class TtEvtBuilder< C >

Template class to fill the TtEvent structure.

Template class to fill the TtEvent structure for:

TtSemiLeptonicEvent TtFullLeptonicEvent TtFullHadronicEvent

event hypothesis, genEvent and extra information (if available) are read from the event and contracted into the TtEvent
