Detailed Description

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

This filter adds label-pushing to a lookahead composition filter using the LookAheadPrefix() method of the matcher argument. It is templated on an underlying filter, typically the basic lookahead or weight-pushing lookahead filter. Label-pushing in composition matches labels as early as possible based on the lookahead information.
