Functions
template<class Weight , class Int >
void	ConvertLattice (const ExpandedFst< ArcTpl< Weight > > &ifst, MutableFst< ArcTpl< CompactLatticeWeightTpl< Weight, Int > > > *ofst, bool invert=true)
	Convert lattice from a normal FST to a CompactLattice FST. More...
template<class Weight , class Int >
void	ConvertLattice (const ExpandedFst< ArcTpl< CompactLatticeWeightTpl< Weight, Int > > > &ifst, MutableFst< ArcTpl< Weight > > *ofst, bool invert=true)
	Convert lattice CompactLattice format to Lattice. More...
template<class WeightIn , class WeightOut >
void	ConvertLattice (const ExpandedFst< ArcTpl< WeightIn > > &ifst, MutableFst< ArcTpl< WeightOut > > *ofst)
	Convert between CompactLattices and Lattices of different floating point types... More...
template<class Weight , class ScaleFloat >
void	ScaleLattice (const std::vector< std::vector< ScaleFloat > > &scale, MutableFst< ArcTpl< Weight > > *fst)
	Scales the pairs of weights in LatticeWeight or CompactLatticeWeight by viewing the pair (a, b) as a 2-vector and pre-multiplying by the 2x2 matrix in "scale". More...
template<class Weight , class Int >
void	RemoveAlignmentsFromCompactLattice (MutableFst< ArcTpl< CompactLatticeWeightTpl< Weight, Int > > > *fst)
	Removes state-level alignments (the strings that are part of the weights). More...
template<class Weight , class Int >
bool	CompactLatticeHasAlignment (const ExpandedFst< ArcTpl< CompactLatticeWeightTpl< Weight, Int > > > &fst)
	Returns true if lattice has alignments, i.e. More...
template<class Real >
void	ConvertFstToLattice (const ExpandedFst< ArcTpl< TropicalWeight > > &ifst, MutableFst< ArcTpl< LatticeWeightTpl< Real > > > *ofst)
	Converts TropicalWeight to LatticeWeight (puts all the weight on the first float in the lattice's pair). More...
