Detailed Description

template<class Arc>
class fst::DeterministicOnDemandFst< Arc >

class DeterministicOnDemandFst is an "FST-like" base-class.

It does not actually inherit from any Fst class because its interface is not exactly the same (it doesn't have the GetArc function). It assumes that the FST can have only one arc for any given input symbol, which makes the GetArc function below possible. Note: we don't use "const" in this interface, because it creates problems when we do things like caching.
