NFABuilder

trait NFABuilder[S, T, G <: (Set), +D <: (DFA), +N <: (NFA), -K >: NFAelements[S, T] <: Matchable, -NZ <: (AutomatonStyle), -DZ <: (AutomatonStyle)]() extends NFABuilder[S, T, G, D, N, K, NZ, DZ] with FABuilder[S, T, N, K, NZ]

Implementation of NFABuilder using `HashMap`s and `HashSet`s.

Type Params
S

The type of all states of the automaton

T

The type of labels on (non-epsilon) transitions of the automaton

Constructor

Creates an immutable NFA corresponding to the automaton described to this builder. This method creates elements of the internal state of the NFA, and passes them to the abstract method assembleNFA: the actual definition of assembleNFA is in the concrete classes (of package org.maraist.fa) implementing this trait.
