Detailed Description

template<class A>
class fst::ComplementFst< A >

Complements an automaton. This is a library-internal operation that introduces a (negative) 'rho' label; use Difference/DifferenceFst in user code, which will not see this label. This version is a delayed Fst.

This class attaches interface to implementation and handles reference counting, delegating most methods to ImplToFst.

Member Data Documentation

template<class A>

const A::Label fst::ComplementFst< A >::kRhoLabel = -2 [static]

Label that represents the rho transition. We use a negative value, which is thus private to the library and which will preserve FST label sort order.
