Detailed Description

template<class F, class M1 = LookAheadMatcher<typename F::FST1>, class M2 = M1, MatchType MT = MATCH_BOTH>
class fst::PushWeightsComposeFilter< F, M1, M2, MT >

This filter adds weight-pushing to a lookahead composition filter using the LookAheadWeight() method of matcher argument. It is templated on an underlying lookahead filter, typically the basic lookahead filter. Weight-pushing in composition brings weights forward as much as possible based on the lookahead information.
