bool ucam::hifst::LoadSparseWeightFlowerLatticeTask< DataT >::load ( const std::string & filename )

inline

Load flower lattice from file.

Remarks: Each rule will be a single arc in the fst with the rule index Tropical Sparse Tuple weight is used. Each arc (rule) has a set of feature weights. The first weight is at offset_+1. Weight indices 1..offset_ are left empty for the language model(s) to fill in.
