Method Description
EnumerateCombinedRules ( ConsList state_set, FuncDecl func, Func GetRules ) : ExprSet[]>>.IEnumerable
GetId ( string symbol ) : int
GetMaxStateId ( IEnumerable rules ) : int
MkAcceptorOutput ( FuncDecl f ) : Expr

Make an acceptor output term for the given symbol and states.
MkLangConj ( IEnumerable states, IEnumerable args ) : Expr

Makes the language acceptance condition for the given states and arguments. For example if states =[{},{q1},{q2,q3},{q2}] and args = [t0,t1,t2,t3] creates the conjunction (($lang(q1,t1) and $lang(q2,t2)) and $lang(q3,t2)) and $lang(q2,t3). Assumes that the enumerations have the same length.
