match()

std::optional< bool > FastReductionMatcher::match ( const HypoJetVector &  jv, xAODJetCollector &  jetCollector, const std::unique_ptr< ITrigJetHypoInfoCollector > &  collector, bool    ) const

overridevirtual

determine whether a set of jets satisfies all hypo conditions.

the jets are packed into jet grpups of length 1. groups_b and groups_e are iterators into the data structure containing these groups. Jet collector is used to transport the jets that matched the hypo conditions. Collector collects information for testing and debugging the final bool argument is used to allow further debugging within the method.

Implements IJetsMatcher.

    Decide if the incomming jet groups satisfiy all the conditions of the

    The leaf nodes are tested first. Jet groups satisfyng the leaves 
    stored in a table. Once all leaves have been processed, the satisfying
    groups are combined, and tested against the aprent nodes.
 
    The procedure is iterated until the entire tree is checked, or
    an unsatisfied condition is found. If no unsatisfied condition,
    there is a match.
