Functions
template<class Arc >
void	GetStateProperties (const Fst< Arc > &fst, typename Arc::StateId max_state, std::vector< StatePropertiesType > *props)
	This function works out various properties of the states in the FST, using the bit properties defined in StatePropertiesEnum. More...
template<class Arc , class I >
void	Factor (const Fst< Arc > &fst, MutableFst< Arc > *ofst, std::vector< std::vector< I > > *symbols)
	Factor identifies linear chains of states with an olabel (if any) only on the first arc of the chain, and possibly a sequence of ilabels; it outputs an FST with different symbols on the input that represent sequences of the original input symbols; it outputs the mapping from the new symbol to sequences of original symbols, as "symbols" [zero is reserved for epsilon]. More...
template<class Arc >
void	Factor (const Fst< Arc > &fst, MutableFst< Arc > *ofst1, MutableFst< Arc > *ofst2)
	This is a more conventional interface of Factor that outputs the result as two FSTs. More...
template<class Arc , class I >
void	ExpandInputSequences (const std::vector< std::vector< I > > &sequences, MutableFst< Arc > *fst)
	ExpandInputSequences expands out the input symbols into sequences of input symbols. More...
template<class Arc , class I >
void	CreateFactorFst (const std::vector< std::vector< I > > &sequences, MutableFst< Arc > *fst)
	The function CreateFactorFst will create an FST that expands out the "factors" that are the indices of the "sequences" array, into linear sequences of symbols. More...
template<class Arc , class I >
void	CreateMapFst (const std::vector< I > &symbol_map, MutableFst< Arc > *fst)
	CreateMapFst will create an FST representing this symbol_map. More...
