Method Detail

neutralAnswer

protected boolean neutralAnswer()

Description copied from class: AbstractAutomataChecker

The answer that should be returned when running into a cycle in the automaton. This should be the neutral element with respect to the operation that's used to combine the results from multiple paths. That is, if there are multiple paths, one of whom is part of a cycle whereas the others are not, then the end result should just depend on the non-cyclic paths. Thus if the results are combined with "any", the neutral element should be false and for "all" it should be true.
