This replacement is recursive. ReplaceFst can be used +// to support a variety of delayed constructions such as recursive +// transition networks, union, or closure. It is constructed with an +// array of Fst(s). One Fst represents the root (or topology) +// machine. The root Fst refers to other Fsts by recursively replacing +// arcs labeled as non-terminals with the matching non-terminal +// Fst. Currently the ReplaceFst uses the output symbols of the arcs +// to determine whether the arc is a non-terminal arc or not. A +// non-terminal can be any label that is not a non-zero terminal label +// in the output alphabet. +// +// Note that the constructor uses a vector of pair<>. These correspond +// to the tuple of non-terminal Label and corresponding Fst. For example +// to implement the closure operation we need 2 Fsts. The first root +// Fst is a single Arc on the start State that self loops, it references +// the particular machine for which we are performing the closure operation. +// +// The ReplaceFst class supports an optionally caching arc iterator: +// ArcIterator< ReplaceFst<A> > +// The ReplaceFst need to be built such that it is known to be ilabel +// or olabel sorted (see usage below). +// +// Observe that Matcher<Fst<A> > will use the optionally caching arc +// iterator when available (Fst is ilabel sorted and matching on the +// input, or Fst is olabel sorted and matching on the output). +// In order to obtain the most efficient behaviour, it is recommended +// to set 'epsilon_on_replace' to false (this means constructing acceptors +// as transducers with epsilons on the input side of nonterminal arcs) +// and matching on the input side. +// +// This class attaches interface to implementation and handles +// reference counting, delegating most methods to ImplToFst. +template <class A, class T = DefaultReplaceStateTable<A> > +class ReplaceFst : public ImplToFst< ReplaceFstImpl<A, T> > { + public: + friend class ArcIterator< ReplaceFst<A, T> >; + friend class StateIterator< ReplaceFst<A, T> >; + friend class ReplaceFstMatcher<A, T>; + + typedef A Arc; + typedef typename A::Label Label; + typedef typename A::Weight Weight; + typedef typename A::StateId StateId; + typedef CacheState<A> State; + typedef ReplaceFstImpl<A, T> Impl; + + using ImplToFst<Impl>::Properties; + + ReplaceFst(const vector<pair<Label, const Fst<A>* > >& fst_array, + Label root) + : ImplToFst<Impl>(new Impl(fst_array, ReplaceFstOptions<A, T>(root))) {} + + ReplaceFst(const vector<pair<Label, const Fst<A>* > >& fst_array, + const ReplaceFstOptions<A, T> &opts) + : ImplToFst<Impl>(new Impl(fst_array, opts)) {} + + // See Fst<>::Copy() for doc. + ReplaceFst(const ReplaceFst<A, T>& fst, bool safe = false) + : ImplToFst<Impl>(fst, safe) {} + + // Get a copy of this ReplaceFst.
